GROUP STRATEGIC REPORT 
 
The directors present their annual report and accounts for Northern Ireland 
Electricity Networks Limited (NIE Networks or the Company) and its subsidiary 
undertakings (the Group) for the year ended 31 December 2017. 
 
The Board of directors of the Group who served during the year are outlined in 
the Group Directors' Report on page 22. 
 
NIE Networks' subsidiary companies are NIE Networks Services Limited and NIE 
Finance PLC. 
 
The Group accounts have been prepared in accordance with International 
Financial Reporting Standards (IFRS) and IFRS Interpretations Committee (IFRIC) 
interpretations as adopted by the European Union and with the Companies Act 
2006 applicable to companies reporting under IFRS. 
 
The Company accounts have been prepared in accordance with FRS 101 - Reduced 
Disclosure Framework and the Company has taken advantage of certain disclosure 
exemptions allowed under this standard. 
 
The financial statements of the Group and the Company have been prepared under 
the historical cost convention, as modified by the revaluation of financial 
derivative instruments at fair value through profit or loss. 
 
Ownership 
 
NIE Networks is part of the Electricity Supply Board (ESB), the vertically 
integrated energy group based in the Republic of Ireland (RoI).  NIE Networks 
is an independent business within ESB with its own Board of Directors, 
management and staff. 
 
Business Model 
 
Principal Activities and Regulation 
 
NIE Networks is the owner of the transmission and distribution networks in 
Northern Ireland and the distribution network operator. SONI Limited (SONI) is 
the transmission system operator and is responsible for transmission system 
design and planning. The Group's principal activities are: 
 
- constructing and maintaining the electricity transmission and distribution 
networks in Northern Ireland and  operating the distribution network; 
 
- connecting demand and renewable generation customers to the transmission and 
distribution networks; and 
 
- providing electricity meters in Northern Ireland and providing metering data 
to suppliers and market operators to enable wholesale and retail market 
settlement. 
 
NIE Networks is a regulated company and its business activities are regulated 
by the Northern Ireland Authority for Utility Regulation (the Utility 
Regulator).  Under its Transmission and Distribution licences NIE Networks is 
required to develop, maintain and, in the case of the distribution system, 
operate an efficient, co-ordinated and economical system of: 
 
- electricity transmission - the bulk transfer of electricity across the high 
voltage network of overhead lines, underground cables and associated equipment 
mainly operating at 275kV and 110kV; and 
 
- electricity distribution - the transfer of electricity from the high voltage 
transmission network and its delivery to consumers across a network of overhead 
lines and underground cables operating at 33kV, 11kV and lower voltages. 
 
NIE Networks manages the assets of the transmission and distribution networks 
on an integrated basis.  The transmission and distribution networks comprise a 
number of interconnected networks of overhead lines and underground cables 
which are used for the transfer of electricity to around 870,000 consumers via 
a number of substations. This network sits between electricity generators and 
consumers.  NIE Networks does not buy or sell electricity, or send any bills to 
electricity consumers (apart from charges for new connections to the network). 
 
During the year an estimated 7.7TWh of electricity was transmitted and 
distributed to consumers in Northern Ireland.  There are 2,200km of 
transmission lines, 47,000km of distribution lines and over 300 major 
substations. NIE Networks' transmission system is connected to that of the RoI 
through a 275kV interconnector and to that in Scotland via the Moyle 
Interconnector. There are also two standby 110kV connections to the RoI. 
 
In addition to its core network activities, NIE Networks provides meters to 
consumers and takes meter readings.  It is responsible for managing market 
registration processes and the provision and maintenance of accurate data to 
support the operation of the competitive retail and wholesale electricity 
markets. 
 
Market Registration and Change of Supplier processes facilitate consumers 
switching suppliers in a timely manner in accordance with retail market rules 
and aggregated data is provided to the Single Electricity Market Operator on a 
daily basis for settlement of the wholesale market. 
 
The Group also provides connections to the network for customers requiring a 
new electricity supply (demand connections) and those seeking to generate 
electricity (generation connections). 
 
The market for greater than 5MW distribution connections has been open to 
competition since May 2016.  For 'contestable' elements of these connections, 
customers can choose whether to accept a quotation from NIE Networks or to 
engage an accredited Independent Connection Provider (ICP) to construct the 
connection. 
 
NIE Networks is completing its preparations for market opening of distribution 
connections lower than 5MW on 28 March 2018. 
 
Revenues 
 
The Group derives its revenue principally through charges for use of the 
distribution system and Public Service Obligation (PSO) charges levied on 
electricity suppliers and charges for transmission services (mainly for use of 
the transmission system) levied on SONI.  Revenue through charges for new 
demand and generation connections is received from the customer in accordance 
with the Statement of Connection Charges, which is revised at least annually. 
 
Price controls 
 
NIE Networks is subject to periodic reviews in respect of the prices it may 
charge for use of the transmission and distribution networks in Northern 
Ireland. 
 
The price control in respect of the fifth regulatory period since privatisation 
(RP5) applied for the period from 1 April 2012 to 30 September 2017. Regulatory 
Period 6 (RP6) commenced on 1 October 2017 and will apply for the period to 31 
March 2024. 
 
The RP6 price control sets ex-ante allowances of GBP697 million for capital 
investment and GBP456 million in respect of operating costs (2017-18 prices). The 
allowances in respect of major transmission load growth projects will be 
considered on a case-by-case basis, for example, the North-South 
Interconnector. The allowances will be adjusted to reflect 50% of the 
difference between the allowances and actual costs incurred. NIE Networks' 
Connections business is largely outside the scope of the RP6 price control 
following the introduction of contestability as referred to above. 
 
The RP6 baseline rate of return of 3.18% plus inflation (weighted average cost 
of capital based on pre-tax cost of debt and post-tax cost of equity) will be 
adjusted to reflect the cost of new debt raised in RP6. This mechanism is new 
for RP6, departing from the former approach of setting an ex-ante allowance, 
and will align the cost of debt component of the return more closely with 
prevailing market conditions at the time of drawdown of new debt. 
 
Strategy 
 
NIE Networks' strategic direction is determined primarily by obligations under 
its Transmission and Distribution Licences.  Its vision is to be a 
high-performing electricity networks company that makes a positive contribution 
to the local community.  Its mission is to distribute electricity in a safe, 
reliable, efficient and environmentally sound manner.  The Group works to its 
stated values concerning safety, employees, customer service, innovation, 
integrity, efficiency and community. 
 
NIE Networks' strategic objectives are: 
 
- the health and safety of employees, contractors and the general public; 
 
- continued investment in Northern Ireland's electricity infrastructure to: 
replace worn assets; facilitate increased customer demand; strengthen the 
reliability of the rural network in severe weather events; and facilitate the 
connection of further renewable generation; 
 
- performance through people by ensuring a working environment that maximises 
the potential of employees; 
 
- value growth incorporating a competitive and transparent cost base; 
 
- maintaining a strong investment grade credit rating; 
 
- strong customer service performance; and 
 
- effective stakeholder engagement. 
 
NIE Networks seeks to discharge its statutory and regulatory obligations in a 
manner which meets these strategic objectives. 
 
Financial Review 
 
Financial Key Performance Indicators (KPIs) 
 
Operating Profit 
 
The Group's operating profit as reported in the accounts was GBP94.9m for the 
year to 31 December 2017, an increase of GBP3.2m on the previous year.  Group 
revenue of GBP261.1m reflects an increase of GBP14.3m from the previous year 
primarily due to a change of accounting estimate in respect of revenue from 
customer connections, together with the phasing of RP5 tariffs.  Group 
operating costs of GBP166.2m increased by GBP11.1m on the previous year primarily 
due to higher depreciation charges reflecting the continual investment in the 
network, together with higher employee costs owing to increased current service 
costs for defined benefit pensions. 
 
FFO Interest Cover 
 
The Group considers the ratio of FFO (funds from operations) to interest paid 
to be one of the key internal measures of the Group's financial health. FFO 
interest cover indicates the Group's ability to fund interest payments from 
cash flows generated by operations. The ratio, as shown in note 6 to the 
accounts, at 3.3 times for the year (2016 - 3.2 times) is above the target 
level of 3.0 times and confirms the Group's continuing financial strength. 
 
Net Assets 
 
The Group's net assets of GBP327.4m increased by GBP33.5m on the previous year 
largely reflecting profit after tax of GBP44.7m together with re-measurement 
gains (net of tax) of GBP6.8m on net pension scheme liabilities partly offset by 
a dividend paid to the shareholder during the year of GBP18.0m. 
 
Cash Flow 
 
Cash and cash equivalents increased by GBP1.9m during the year reflecting net 
cash flows from operating activities of GBP132.8m together with a drawdown on the 
Group's Revolving Credit Facility (RCF) of GBP94.9m, partly offset by investing 
activity out flows of GBP207.8m and a dividend paid of GBP18.0m. Cash flows from 
operating activities of GBP132.8m are GBP53.6m lower than the previous year largely 
reflecting a reduction in trade and other payables as a result of payments on 
account decreasing as the pipeline of generation connections nears completion. 
 
Financial Risk Management 
 
The main financial risks faced by the Group relate to liquidity, funding, 
investment and financial risk, including interest rate and counterparty credit 
risk.  The Group's objective is to manage financial risks at optimum cost.  The 
Group employs a continuous forecasting and monitoring process to manage risk. 
 
Capital Management and Liquidity Risk 
 
The Group is financed through a combination of equity and debt finance. 
Details in respect of the Group's equity are shown in the Statement of Changes 
in Equity and in note 22 to the accounts.  The Group's debt finance at the year 
end comprised bonds of GBP175.0m and GBP400.0m (GBP174.8m and GBP398.5m respectively 
net of issue costs) which are due to mature in September 2018 and June 2026 
respectively and GBP114.0m drawn down from a GBP150.0m RCF from ESB which is due to 
mature in September 2018. 
 
The Group's liquidity risk is assessed through the preparation of cash flow 
forecasts.  The Group's policy is to have sufficient funds in place to meet 
funding requirements for the next 12 - 18 months. In light of the maturity of 
the GBP175.0m bond and GBP150.0m RCF in September 2018, the Group is currently 
assessing longer term financing options in conjunction with its parent, ESB. 
The Group is satisfied that it will have access to funds in advance of the 
maturity of existing facilities as it has secured an option to extend the 
existing GBP150.0m RCF from ESB to GBP400.0m with maturity deferred until March 
2019. 
 
The Group's policy in relation to equity is to finance equity dividends from 
accumulated profits.  In relation to debt finance, the Group's policy is to 
maintain a prudent level of gearing. 
 
NIE Networks' licences contain various financial conditions which relate 
principally to the availability of financial resources, borrowings on an arm's 
length basis, restrictions on granting security over the Group's assets and the 
payment of dividends.  The Group is in compliance with these conditions. 
 
The Group maintained its investment grade credit rating from Standard & Poor's 
during the year. 
 
Interest Rate Risk 
 
The GBP175.0m and GBP400.0m bonds are denominated in sterling and carry fixed 
interest rates of 6.875% and 6.375% respectively.  The RCF is denominated in 
sterling and carries a floating interest rate based on LIBOR. 
 
Given that 83% of the Group's total borrowings carry a fixed interest rate, the 
Group does not consider that it is significantly exposed to interest rate risk. 
 
Since December 2010, NIE Networks has held a GBP550m portfolio of RPI linked 
interest rate swaps. The RPI swaps were put in place by the Viridian Group (the 
Group's previous parent undertaking) in 2006 to better match NIE Networks' debt 
and related interest payments with its inflation-linked regulated assets and 
associated revenue. The swaps are considered to be economic hedges for NIE 
Networks' regulated revenue and asset base. As part of the acquisition of NIE 
Networks by ESB in 2010, the swaps were novated to NIE Networks. 
 
Following a restructuring in 2014 the swaps have a mandatory break period in 
2022.  At the same time that the restructuring took effect, and in order to 
maintain the back to back matching put in place with ESBNI Limited (ESBNI) in 
2011, the Company entered into RPI linked interest rate swap arrangements with 
ESBNI, the immediate parent undertaking of the Company, which have identical 
matching terms to the restructured swaps.  The back to back matching swaps with 
ESBNI ensure that there is no net effect on the accounts of the Company and 
that any risk to financial exposure is borne by ESBNI.  Further details of the 
swaps, including fair values, are disclosed in note 17 to the accounts. 
 
Credit Risk 
 
The Group's principal financial assets are cash and cash equivalents, trade and 
other receivables (excluding prepayments and accrued income) and other 
financial assets as outlined in the table below: 
 
Year to 31 December                                                2017           2016 
                                                                     GBPm             GBPm 
 
Cash and cash equivalents                                          11.2            9.3 
 
Trade and other receivables (excluding prepayments and             55.2           58.4 
accrued income) 
 
Other financial assets - current and non-current                  579.5          598.0 
                                                                 ------         ------ 
 
                                                                  645.9          665.7 
                                                                 ------         ------ 
 
The Group's credit risk in respect of trade receivables from licensed 
electricity suppliers is mitigated by appropriate policies with security 
received in the form of cash deposits, letters of credit or parent company 
guarantees.  With the exception of certain public bodies, payments in relation 
to new connections or alterations are received in advance of the work being 
carried out.  Payments received on account are disclosed in note 15 to the 
accounts. 
 
Other financial assets comprise RPI linked interest rate swap arrangements 
entered into with ESBNI as outlined above.  The counterparty risk from ESBNI is 
not considered significant given ESB's investment in the Group and ESB's strong 
investment grade credit rating. 
 
The Group may be exposed to credit-related loss in the event of non-performance 
by bank counterparties.  This risk is managed through conducting business only 
with approved counterparties which meet the criteria outlined in the Group's 
treasury policy. 
 
Further information on financial instruments is set out in the notes to the 
accounts. 
 
Going Concern 
 
The Group's business activities, together with the principal risks and 
uncertainties likely to affect its future performance, are described in this 
Group Strategic Report.  As noted in the section on capital management and 
liquidity risk, the Group is financed through a combination of equity and debt 
finance with elements of existing debt finance expected to mature in September 
2018. 
 
On the basis of their assessment of the Group's financial position, which 
included a review of the Group's projected funding requirements for a period of 
12 months from the date of approval of the accounts and consideration of the 
option to extend and increase the existing RCF from ESB, the directors have a 
reasonable expectation that the Group will have adequate financial resources 
for the 12-month period. Accordingly the directors continue to adopt the going 
concern basis in preparing the annual report and accounts.

Health & Safety 
 
Ensuring the health, safety and wellbeing of employees, contractors and the 
general public continued to be the number one value at the core of all NIE 
Networks' business operations.  The aim is to provide a zero-harm working 
environment where risks to health and safety are assessed and controlled.  This 
is achieved by the promotion of a positive health and safety culture and 
adherence to legislation and recognised safety standards.  The approach to 
safety is based on the principles of: Leadership; Competence; Compliance and 
Engagement. 
 
The health and safety management system is accredited to OHSAS 18001 standard 
and based on best practice guidance from the Health and Safety Executive for 
Northern Ireland (HSENI) and the Institute of Directors.  NIE Networks 
continues to engage with various organisations including the HSENI, the NI 
Utilities Safety Group, the NI Authority for Roads and Utilities Committee, the 
NI Environment Agency and various Energy Networks Association (ENA) health and 
safety committees to share information and improve safety performance and 
learning. 
 
The target for lost time incidents continues to be set at zero: there was one 
incident during the year (2016 - one) caused by the failure of a mobile 
elevated work platform which resulted in lost working time for an employee. 
 
Safety Engineers are aligned with organisational structures on a 'Business 
Partner' relationship which facilitates integration of skills and allows 
influence and support.  During 2017 the Safety Team continued to support all 
business units with particular focus on the following areas: 
 
- the reporting, analysis and investigation of "near miss" events which is key 
to improving safety performance.  The quality of reports continued to improve 
with approximately 58% of incidents classed as "good catch".  Each report is 
analysed by a team of Safety Engineers to ensure consistency and accurate 
follow-up, enabling further improvements in equipment and operational 
procedures to be identified and addressed; 
 
- formalisation of all incident investigation procedures with appropriate 
monthly reporting; 
 
- completion of process safety workshops examining maintenance and 
communication processes with recommendations to be implemented during 2018; 
 
- three external audits were completed with zero non-conformances; 
 
- continued programme of formal safety training for employees and contractors 
including; safety seminars delivered to all staff to increase risk awareness 
and perception, the publication of a monthly Safety newsletter and 
comprehensive contractor management arrangements to ensure that contractors 
adhere to the same safety rules and requirements as employees; 
 
- 80 employees have attained certificates in Construction, Health and Safety 
from the National Examination Board in Occupational Safety and Health (NEBOSH); 
 
- site safety inspections continued throughout the year with over 4,000 
inspections completed: the focus of the inspections was coaching and 
encouraging good site behaviours while ensuring compliance was achieved.  In 
line with the Leadership and Engagement principles these were completed by a 
range of staff including the Managing Director, Executive Committee members, 
business unit managers and front-line managers; 
 
- continued focus on identifying the causes of road traffic incidents including 
post-incident driver appraisals and training where required; and 
 
- a programme of health and wellbeing checks, health screening and lifestyle 
advice was made available to all staff to coincide with "European Health & 
Safety Week". 
 
Updates on safety performance are provided to each Executive Committee and 
Board meeting.  This provides a level of regular assurance against objectives 
agreed in the annual Health, Safety and Wellbeing Business Plan. 
 
In recognition of its strong safety focus, NIE Networks won two awards at the 
All-Ireland Occupational Safety Awards in 2017. 
 
Network Performance and Customer Service 
 
The provision of a safe, reliable and responsive electricity service, which 
endeavours to meet the standards customers expect, and to deal with customers 
professionally, courteously and respecting their individual needs, is key to 
NIE Networks values. 
 
Against the backdrop of the ramp up in the network investment programme during 
2017, NIE Networks continued to manage outages required for essential 
maintenance and development in order to minimise the occasions and length of 
time that customers are off supply.   Performance of the distribution network 
is measured in its availability - the number of minutes lost per customer 
(CML). 
 
CML due to planned outages is the average number of minutes lost per customer 
for the period through pre-arranged shutdowns for maintenance and construction: 
the number of planned CML for 2017 was 62 minutes (2016 - 65 minutes). The 
average number of CML due to faults on the distribution network in 2017 was 57 
minutes, a slight increase on the previous year (2016 - 56 minutes) reflecting 
less favourable weather conditions during the early part of the year. 
 
The Utility Regulator sets overall and guaranteed standards of performance. 
The majority apply to services provided, for example the timely restoration of 
customers' supplies following an interruption, and prescribed times for 
responding to customers' voltage complaints.  All of the overall standards were 
achieved. In 2017 there was one default against Guaranteed Standards of 
Performance for customer service activities delivered (2016 - none).   During 
the year 91.5% (2016 - 90%) of electricity supplies were restored within three 
hours, within the regulatory standard of 87%. 
 
NIE Networks continues to test and confirm the robustness of its emergency 
response capabilities during severe weather events in order to effectively 
restore supply to all customers.  The significant commitment from all staff 
helps to ensure that NIE Networks manages effectively this very important 
aspect of the business with every employee having an "escalation" role in 
addition to their normal day-to-day role. 
 
During the year there were three occasions (wind and gales in February, a 
lightning storm in August, and Storm Ophelia in October) where adverse weather 
caused damage to the network and affected thousands of customers supplies. 98% 
of customers were restored within 24 hours. 
 
The focus on reducing the number of avoidable complaints continued and the 
number of complaints received from customers was 4% lower than in the previous 
year. Individual complaints received are analysed and assessed, based on the 
specific circumstances, to determine whether or not the complaint was 
avoidable. 
 
The continued strong focus on customer service limits the number of instances 
when customers are dissatisfied to the extent that they refer a complaint to 
the Consumer Council for Northern Ireland (CCNI) for review.  During the year 
two complaints were taken up by the CCNI on behalf of customers (Stage 2 
Complaints to the CCNI) (2016 - none). 
 
Across NIE Networks there has been a focus on reviewing customer service 
activities in order to improve delivery in all areas. Identified improvements 
will continue throughout 2018 as part of the Group's "Customer Service Action 
Plan" including a multi-channel approach to communication with the NIE Networks 
Facebook and Instagram channels launched during 2017. 
 
Connections 
 
NIE Networks' Connections business provides safe, secure, reliable and timely 
electricity connections within Northern Ireland.  The purpose of the 
Connections business is to provide an excellent customer experience through the 
connection process and to provide least cost technically acceptable 
connections.  Focus throughout 2017 remained on improving customer service 
throughout the connections process and connecting as much generation capacity 
as possible given the transmission capacity constraints on the network. 
 
The majority of connections work undertaken relates to demand or load 
connections, covering: the provision of  new connections to homes, businesses, 
farms and housing developments; altering existing connections including 
replacing electrical equipment, installing new earthing or diverting equipment; 
and increasing or decreasing the load of electrical equipment to cater for new 
requirements.  The number of applications during the year for these types of 
"demand" connections was lower than the previous year.  The number of demand 
connections completed during the year was also lower than in 2016. 
 
During 2017, the Connections business was restructured in response to evolving 
customer needs with process and technology improvements, and increased customer 
and stakeholder engagement.  Average life cycle times from initial job 
registration to connection to the network reduced by around 10%.  This was 
achieved at a time when significant volumes of generation connections were also 
delivered. 
 
Generation connections fall into three broad categories - large scale, small 
scale and micro: 
 
- Large scale generation (typically 5 - 40MW) mainly takes the form of 
windfarms connected to the transmission and distribution networks; 
 
- Small scale generation (typically 20kW - 5MW) takes the form of single wind 
turbines, anaerobic digesters,  photovoltaic and hydro installations connected 
to the distribution network; and 
 
- Micro-generation (4 - 12kW) is typically photovoltaic panels on domestic 
rooftops and normally connects directly to customer premises. 
 
Significant progress was made during 2017 in completing generation connections 
in line with developers' requirements to meet accreditation deadlines for the 
Northern Ireland Renewables Obligation (NIRO) scheme. 
 
During 2017, 287MW of large scale generation was connected to the network, 
taking the total large scale generation connected to the network to 1,105MW 
(76% of total renewable generation capacity).  A substantial proportion of 
large scale generation (150MW) was connected through windfarm clusters at Gort, 
Rasharkin and Tremoge. Windfarm clusters are 110kV connection nodes established 
in the vicinity of a number of windfarm projects to enable more efficient 
connection on a 'hub and spoke' basis with associated environmental, technical 
and operational benefits.  In overall terms they reduce the route length 
required to connect all projects and enable additional capacity to be 
connected. 
 
During 2017, 71MW of small scale generation was connected to the network, 
taking the total connected for small scale generation to 260MW (18% of total 
renewable generation capacity).  A further 37MW is committed and is at various 
stages of the connection process.  Micro-generation connections to the network 
increased to 82MW (6% of total renewable generation capacity) including 3MW 
added in 2017. 
 
With over 1.4GW of renewable generation connected to the network by the end of 
2017 and over 0.3GW of further capacity committed to be connected, the total 
connected renewable capacity is expected to reach more than 1.7GW by 2020. 
 
NIE Networks continues to seek ways to connect generators to the network and, 
following consultation with the industry to assess how best to maximise the 
uptake of remaining capacity on the transmission and distribution networks, a 
decision paper was published jointly by NIE Networks and SONI during 2016. 
Since then 185 generation connection offers totalling circa 250MW have been 
issued. 
 
Due to the lack of further capacity on the transmission and distribution 
networks, NIE Networks initiated a joint consultation with SONI in January 2018 
to develop alternative approaches to conventional investment.  The aim of this 
consultation is to bring forward solutions which are commercially viable for 
developers and facilitate the adoption of SMART solutions to connect additional 
renewable generation. The consultation closes in March 2018 with a decision 
paper expected to be published before the end of June 2018. 
 
The market for greater than 5MW distribution connections has been open to 
competition since May 2016.  For 'contestable' elements of these connections, 
customers can choose whether to accept a quotation from NIE Networks or to 
engage an accredited Independent Connection Provider (ICP) to construct the 
connection. 
 
NIE Networks is completing its preparations for market opening of distribution 
connections lower than 5MW on 28 March 2018 which has involved significant IT 
development, implementation of new processes and staff training to facilitate 
competition. 
 
Sustainability 
 
NIE Networks' Environmental Policy commits to protecting the environment and 
mitigating the impact of its activities upon the environment. The environmental 
management system is accredited to ISO 14001 and transitioned to the new 
version of the standard in 2017. It is designed to ensure compliance with all 
relevant legislative and regulatory requirements and, where practical and 
economically viable, NIE Networks seeks to develop standards in excess of such 
requirements, introducing best practice solutions where possible.  The annual 
environmental business plan sets out detailed plans to ensure the achievement 
of the key objectives of: minimising the risks of air and water pollution and 
land contamination; minimising the impact on local communities; enhancing 
energy and resource consumption efficiency and waste management practices 
whilst ensuring appropriate overall environmental management. 
 
During 2017 there was continued focus on each of the following areas: 
 
- reducing the number of environmental incidents, with a 23% reduction 
achieved, and NIE Networks' remediation process deemed 'best practice' by the 
British Standards Institute; 
 
- waste management targets with the recycling rate for all hazardous and 
non-hazardous waste (excluding excavation from roads and footpaths, civil 
projects excavation and asbestos removal) remaining high at 98% (2016 -  98%); 
and 
 
- improving the management of biodiversity working closely with Ulster 
Wildlife. 
 
In Business in the Community's 2017 Northern Ireland Environmental Benchmarking 
Survey NIE Networks retained its top level Platinum Award, again performing 
well in excess of the utility sector average. 
 
Network Investment 
 
During the year the level of capital investment undertaken increased to 
successfully deliver the physical outputs specified in the RP5 network 
investment plan.  In 2017 NIE Networks invested a total of GBP108.9m (2016 - GBP 
101.4m) (net of customer contributions) in transmission and distribution 
networks, representing an increase of 7% on the prior year.  The investment was 
primarily in relation to the refurbishment and replacement of worn transmission 
and distribution assets to maintain reliability of supply and ensure the safety 
of the network. 
 
During the year over 1,800km of transmission and distribution overhead lines 
were refurbished as part of an on-going programme.  Tree cutting is an 
essential ongoing programme to maintain the networks' resilience to storm 
conditions and during the year tree cutting was carried out along 8,600km of 
overhead lines. 
 
Other key investments during the year included: 
 
- completion of refurbishment works at three 110/33kV substations; 
 
- substantial completion of three 275/110kV substations (at Kells, Castlereagh 
and Tandragee); and 
 
- completion of a 50km 110kV circuit between Tamnamore and Omagh required to 
reinforce the existing transmission overhead line infrastructure in Northern 
Ireland to facilitate the flow of power from renewable generation in the west 
to the demand centres in the east of Northern Ireland. 
 
Market Operations 
 
NIE Networks continued to achieve full compliance with its regulatory 
obligations in respect of customer appointments for metering work.  Each year 
approximately three million visits to customer properties are made to take 
meter readings and, in 2017, NIE Networks continued to meet its regulatory 
standard to obtain actual meter readings from 99.5% of all customers once per 
year, therefore ensuring that electricity consumption is calculated accurately 
and minimising the number of estimated bills issued by electricity suppliers. 
 
NIE Networks also has certain obligations under the Trading and Settlement Code 
to provide aggregated meter data for the purposes of settlement of the 
wholesale Single Electricity Market.  NIE Networks continued to be fully 
compliant with these obligations with no breaches of the Code since its 
introduction in 2007. 
 
A major programme to replace meters that have reached the end of their life 
cycle continued during 2017 with NIE Networks replacing 101,000 meters during 
the year in line with programme targets. This programme has involved the 
replacement of circa 25% of customers' meters since it commenced in 2015. 
 
People 
 
NIE Networks' resourcing strategy is to use highly skilled insourced labour for 
core strategic activities working in partnership with bought-in-services as 
appropriate.  This ensures that knowledge and skills are retained, allows 
greater agility and flexibility to redeploy employees where needed and builds a 
strong culture of engaged employees motivated to deliver business objectives. 
The organisation continues to face a number of demanding challenges. 
Organisation management structures have continued to be streamlined creating 
development opportunities for all levels of employees.  The number of employees 
at the end of 2017 was 1,273 (2016 - 1,277). 
 
Against the backdrop of the RP6 price control determination and cost reduction 
challenges due to market opening in NIE Networks' Connections business, 
management considered a range of cost reduction initiatives including a 
restructuring voluntary exit arrangement under which 61 employees left the 
business during 2017. 
 
On 5 February 2018, management tabled further cost reduction proposals as part 
of a consultation with employee representatives which aims to reduce the number 
of job roles by 90 across the Group (7% of the workforce) and align future pay 
increases with RP6 allowances. 
 
Training and Development 
 
NIE Networks seeks to attract, develop and retain highly skilled people through 
its apprenticeship, graduate, apprentice-to-graduate, scholarship and 
sponsorship programmes.  The Group's Technical Training Centre, which includes 
Apprentice Training, continued to maintain its extremely high standards and 
again achieved an "Outstanding" classification in its annual inspection by the 
Education and Training Inspectorate. The Group's Technical Training Centre also 
received accreditation from the Institution of Engineering and Technology (IET) 
for its apprenticeship programme. 
 
NIE Networks is committed to a working environment which enables employees to 
realise their maximum potential and to be appropriately challenged and fully 
engaged in the business, with opportunities for skills enhancement and personal 
development.  Human Resources policies are aligned with key business drivers 
including: performance and productivity improvement; clearly defined values and 
behaviours; a robust performance management process; and a strong commitment to 
employee development. 
 
A strong focus on development continued during the year with a high percentage 
of employees involved in a variety of training and development programmes and 
initiatives which included leadership skills programmes, formal qualifications, 
role enhancement, role changes, team development initiatives, coaching and 
mentoring. 
 
NIE Networks continues to promote the professional development of its engineers 
through the IET Professional Registration Scheme and proactively encourages and 
supports more employees to become IET members and Chartered Engineers. During 
2017 14 engineers and technicians achieved IET professional membership at 
varying levels. 
 
Equality and Diversity 
 
NIE Networks is proactive in implementing and reviewing human resource policies 
and procedures to ensure compliance with fair employment, sex discrimination, 
equal pay, disability discrimination, race discrimination, sexual orientation 
and age discrimination legislation.  NIE Networks is committed to providing 
equality of opportunity for all employees and job applicants with ongoing 
monitoring to ensure that equality of opportunity is provided in all employment 
practices.  The Group uses outreach initiatives to actively seek female 
applications in male dominated job roles. 
 
Group policy is to provide people with disabilities equal opportunities for 
employment, training and career development, having regard to aptitude and 
ability.  Any member of staff who becomes disabled during employment is given 
assistance and re-training where possible. 
 
Sickness Absence 
 
The proactive management of absenteeism is to the mutual benefit of the 
organisation and its employees.  An employee health and wellbeing policy 
covering stress management is in place, with specific policies on mental 
health, alcohol and drug-related problems and non-smoking.  External 
occupational health and counselling services are available for all employees. 
The Health and Wellbeing Forum and champions across the business rolled out 
various initiatives during the year to provide additional guidance and support 
to enable employees to proactively manage their own health and wellbeing. 
Sickness absence during the year was 3.1%, an increase of 0.5% from the 
previous year owing to long-term sickness absences. 
 
Employee Engagement 
 
NIE Networks won the 2017 UK Chartered Institute of Personnel and Development 
Award for Employee Engagement Strategy in recognition of its efforts in 
engaging with its employees. NIE Networks places considerable emphasis on 
employee participation and engagement.  The Employee Engagement Board ensures, 
through local representatives of employee Focus Groups, that there is a strong 
focus on continued engagement. Company wide employee forums focussing on the 
areas of Health & Wellbeing, Digital Strategy, Innovation and Employee Voice 
continue to grow. 
 
Employee relations are positive and constructive. During 2017 the monthly 
Employee Relations Forums, comprising management and trade union 
representatives, have progressed a wide range of employee relations issues. 
 More formal meetings are held regularly between senior managers and 
representatives of employees and their trade unions to discuss more complex 
issues. 
 
There is a formal induction programme for all new-starts including meeting with 
senior management.  During the year employees were kept informed of NIE 
Networks' objectives, plans, financial and operational performance and their 
effect on them as employees through the monthly newsletter, monthly team 
briefings and via presentations by the Managing Director.  A significant 
portion of staff have performance bonus arrangements which are partly aligned 
to the Group's financial and operational performance. 
 
Investors in People 
 
During 2017 NIE Networks was accredited with Gold level following assessment 
against the Investors in People Sixth Generation Standard. 
 
Looking Forward 
 
Key priorities for 2018: 
 
- ensuring the health and safety of employees, contractors and the general 
public will continue to be the top priority: achieving a zero-harm work 
environment through implementation of injury and accident-free initiatives; 
 
- delivering the cost reduction plan against the backdrop of the RP6 price 
control determination and market opening in customer connections; 
 
- securing efficient financing to fund the RP6 programme; 
 
- delivering the generation connections pipeline; 
 
- delivering improved customer service through the continuing "Think Customer" 
programme; 
 
- opening the connections market to further competition with full market 
opening on 28 March 2018; 
 
- continued investment in employees to enhance NIE Networks' capability; and 
 
- engaging effectively with key stakeholders. 
 
Risk Management 
 
Risk Management Framework 
 
The Board has overall responsibility for risk management and internal control. 
The Board ensures that the Group's risk exposure remains proportional to the 
pursuit of its strategic objectives and longer term stakeholder value.  It has 
adopted a Risk Management Policy and Governance Framework to support its 
oversight of risk throughout the Group. 
 
The Board delegates responsibility for oversight of risk to the Audit & Risk 
Committee in accordance with the Committee's Terms of Reference. The Audit & 
Risk Committee retains overall responsibility for ensuring that enterprise 
risks are properly identified, assessed, reported and controlled on behalf of 
the Board in its consideration of overall risk appetite, risk tolerance and 
risk strategy. As a regulated utility NIE Networks is prudent in its overall 
management of the business and has a limited appetite for and tolerance of 
risk. 
 
The process of considering the Group's exposure to risk and the changes to key 
risks has assisted the Board in its review of strategy and the operational 
challenges faced by the Group. 
 
NIE Networks' risk management framework provides clear policies, processes and 
procedures to ensure a consistent approach to risk identification, evaluation 
and management across the Group and includes appropriate structures to support 
risk management and the formal assignment of risk responsibilities to 
facilitate managing and reporting on individual risks. 
 
The Risk Management Policy is reviewed annually by the Board and sets out the 
high level principles and policy requirements that form the basis of risk 
management within NIE Networks and also outlines the risk management roles and 
responsibilities and the main organisational and procedural arrangements that 
apply to support the effective management of risk.  At Executive level, the 
Risk Management Committee (RMC) oversees and directs risk management in 
accordance with the approved policy. The RMC comprises a number of Executive 
Committee members and senior managers and is chaired by the Finance Director. 
The RMC considers risk assessments carried out by each business unit and the 
risk status and mitigation strategies are reviewed biannually.  The RMC reports 
on its activities to the Executive Committee, Audit & Risk Committee and the 
Board throughout the year.  The internal audit function reports to the Audit & 
Risk Committee, independent of management, and has provided independent 
assurance to the Audit & Risk Committee on the adequacy and effectiveness of 
NIE Networks' system of governance, risk management and control. 
 
Principal Risks and Uncertainties 
 
NIE Networks principal risks persisted from 2016 into 2017, although with some 
movement on the relative ranking of risks and some changes to the key risk 
drivers. The Board agreed the principal risks and the detailed risk plan 
following consideration and recommendation by the Audit & Risk Committee. The 
principal risks and uncertainties that affect the Group along with the main 
mitigating strategies deployed are outlined on the following pages.

                                  apprenticeship, trainee and sponsorship programmes to 
                                  ensure that appropriate resources are in place to 
                                  meet the Group's regulatory obligations. 
Failure to develop and retain 
staff.                            People development is a key priority for the Group 
                                  with continued investment in staff training, skills 
                                  development and on-going performance improvement. 
                                  Focused management development programmes are in 
                                  place to maximise the potential of staff and ensure 
                                  adequate succession planning. 
 
Emerging risks 
 
The risk management framework enables the Group to identify, analyse and manage 
emerging risks to help identify exposures as early as possible. This is managed 
as part of the same process to identify principal risks and is reviewed and 
monitored in conjunction with principal risks. 
 
High Impact Low Probability (HILP) risks 
 
As a provider of critical national infrastructure, NIE Networks is acutely 
aware of the potential impact of this category of risk for the Group. A full 
review of HILP risks was undertaken in 2017 and agreed by the Board. 
 
Business Continuity 
 
NIE Networks is responsible for the provision of critical infrastructure and 
disruptions to certain services and operations are potentially damaging to the 
economy, to society and to NIE Networks' business. The Group has in place a 
robust set of business continuity plans and processes to ensure that our 
responses are well managed and executed. The exercising and testing of these 
plans is key to ensuring NIE Networks' preparedness.

CORPORATE SOCIAL RESPONSIBILITY 
 
NIE Networks provides a vital service to every home, farm and business in 
Northern Ireland as part of its day-to-day work in delivering electricity 
supplies.  Through its mainstream business activities and various specific 
initiatives the Group seeks to make a positive impact on the communities in 
which it operates.  Details of health and safety management, employment 
policies and initiatives and sustainability performance during 2017 can be 
found in the Operational Review on pages 8 to 14.  Initiatives undertaken 
during the year to support NIE Networks' principal Corporate Social 
Responsibility (CSR) themes and priorities are described below. 
 
During the year NIE Networks employees attended around 160 events to promote 
safety around electricity and provide skills, careers advice and guidance. 
 
Safety 
 
Electricity provides a vital service for all people in Northern Ireland, 
however it is dangerous and NIE Networks aims to continually heighten and 
improve the awareness of those working in the close vicinity of the electricity 
network to stay safe and to teach children how to identify electricity 
equipment and to avoid it.  A major ongoing safety programme involves employees 
at all levels and is developed to address new safety concerns such as drones or 
other objects which come into close proximity with the electricity network. 
 
During 2017, around 28,000 farmers and contractors received safety advice from 
NIE Networks at farm safety events.  Safety presentations were made to 
contractors in the transport industry and to other utilities and their 
contractors. 
 
NIE Networks' "Kidzsafe" programme continued with over 10,000 schoolchildren 
participating in the interactive programme to educate and raise awareness of 
the dangers of the electricity network in an effort to reduce incidences of 
electricity-related injuries.   NIE Networks continued to utilise the dedicated 
safety training facility for children and young people, known as RADAR (Risk 
Avoidance and Danger Awareness Resource). 
 
The Group continued to work with the Police Service of Northern Ireland (PSNI), 
the network operators in Great Britain and other utilities in Northern Ireland 
to address the dangerous issue of metal theft.  Thieves targeting electrical 
installations endanger themselves, employees and the wider public. 
 
NIE Networks' safety advice is supplemented by a proactive media campaign, 
social media campaign and information available on its website at 
www.nienetworks.co.uk/Safety. 
 
Customer Care 
 
NIE Networks aims to deliver electricity safely and reliably to customers and 
to respond quickly and efficiently should a power cut occur unexpectedly.  A 
series of presentations were made to key customer and government bodies and 
elected representatives on how NIE Networks repairs network faults and the 
Group's investment plans during the RP6 price control. 
 
Arrangements are in place with ESB Networks, Northern Ireland Water, BT and 
Phoenix Natural Gas to provide mutual support, for example by sharing resources 
and equipment, so that customers' utility supplies can be restored more quickly 
during periods of severe weather or other emergency situations.  In addition, 
together with the councils, emergency planners, health trusts and other 
organisations, NIE Networks has arrangements in place to respond to wider 
community needs in the event of customers being without electricity for an 
extended period of time due to severe weather or an emergency situation. 
 
NIE Networks' critical care information service is a priority service for 8,000 
customers who rely on electricity for their healthcare needs with customers or 
their carers receiving prioritised information on faults or planned work on the 
network. 
 
The Group works with electricity suppliers to offer a Password scheme to 
reassure customers that the employee visiting their home or premises is a 
genuine caller, whereby NIE Networks delivers a pre-agreed password to the 
customer before being allowed to enter a property. 
 
Work Experience and Educational Outreach 
 
NIE Networks is conscious of the ongoing need to encourage and develop 
tomorrow's workforce.  By its nature power engineering is highly skilled and 
specialist and requires many years of training.  With fewer students choosing 
science and technology subjects, coupled with the need to invest heavily in 
network renewal and investment projects, the electricity industry faces a 
significant skills shortage in the future.  NIE Networks therefore continues to 
engage proactively with students to consider engineering as a career, through a 
wide range of educational outreach initiatives including: 
 
- main sponsor of "Skills NI", a two day careers event for 14-19 year olds with 
around 75 exhibitors and connecting around 8,000 young people with job, career 
and skills opportunities across Northern Ireland; 
 
- links with over 80 schools, most of the further educational colleges and the 
two universities to promote opportunities from taking Science, Technology, 
Engineering and Maths (STEM) subjects; 
 
- offering 4 further Electrical & Electronic Engineering scholarships at 
Queen's University Belfast taking the total number of NIE Networks' scholarship 
students to 25; 
 
- work experience for GCSE and A-Level students studying STEM subjects and 
sponsoring, mentoring and the facilitation of a four week research and 
development experience for two A-Level students via the Nuffield Bursary as 
well as bursaries for two Arkwright students; 
 
- sponsoring the IET Northern Ireland First Lego League, a global robotics 
challenge, supporting participating schools with engineering mentoring and 
providing a bursary for the winning team to represent Northern Ireland in the 
UK First Lego League final;` 
 
- engineering mentoring to school children participating in the Sentinus "SMART 
Energy", "Team R&D" and "Engineering Futures" programmes; 
 
- providing advice and assistance at numerous interview skills and assessment 
sessions in conjunction with eye4education; 
 
- working with Malone College in supporting young people via the delivery of 
site visits and skill development workshops; and 
 
- providing financial support to "Little Women NI" for a workshop encouraging 
young girls to develop skills in confidence, communication, creativity, 
leadership and teambuilding. 
 
Community Initiatives 
 
NIE Networks continues to be a member of Business in the Community (BiTC). 
Throughout 2017 employees served on the boards of 18 local voluntary, community 
and social enterprise organisations through BiTC's "Business on Board" 
programme. NIE Networks also participates in BiTC's "PLACE" Leadership Team, 
which seeks opportunities to promote community regeneration through employee 
volunteering. 
 
The Group continues to support the PSNI Quick Check Scheme which encourages 
homeowners and particularly the elderly and vulnerable to check the identity of 
callers at their homes and provides a 24 hour telephone helpline. 
 
Charitable Giving and Sponsorship 
 
Charitable giving by employees is promoted through the NIE Networks Staff and 
Pensioners Charity Fund, in addition to which the Group contributed GBP10,000 
during the year.  In 2017 the Charities Fund supported Autism projects, 
including Adam's Camp and Autism NI, by donating GBP9,500. 
 
NIE Networks is an active member of and provides financial support to the CBI, 
the Chamber of Commerce, Women in Business, the Institute of Directors and the 
Centre for Competiveness in Northern Ireland.

its comments on accounting, financial control and other audit issues. 
 
In addition, during the year the Audit & Risk Committee reviewed its own 
effectiveness as part of the Board's performance evaluation. 
 
Internal Control Framework 
 
The directors acknowledge that they have responsibility for the Group's systems 
of internal control and risk management and monitoring their effectiveness. 
The purpose of these systems is to manage, rather than eliminate, the risk of 
failure to achieve business objectives, to provide reasonable assurance as to 
the quality of management information and to maintain proper control over the 
income, expenditure, assets and liabilities of the Group.  Strong financial and 
business controls are necessary to ensure the integrity and reliability of 
financial information on which the Group relies for day-to-day operations, 
external reporting and for longer term planning. 
 
The Group has in place a strong internal control framework which includes: 
 
- a code of ethics that requires all Board members and employees to maintain 
the highest ethical standards in conducting business; 
 
- a clearly defined organisational structure with defined authority limits and 
reporting mechanisms; 
 
- comprehensive budgeting and business planning processes with an annual budget 
approved by the Board; 
 
- a continuous forecasting and monitoring process to manage financial risk; 
 
- an integrated accounting system with a comprehensive system of management and 
financial reporting. A monthly financial report is prepared which includes 
analysis of results along with comparisons to budget, forecasts and prior year 
results.  These are reviewed by the Executive Committee and the Board members 
on a monthly basis; 
 
- the financial control framework reviewed in accordance with statutory and 
regulatory obligations; 
 
- a comprehensive set of policies and procedures relating to financial and 
operational controls including health and safety, regulation, HR, asset 
management, risk management and capital expenditure; 
 
- a risk management framework including the maintenance of risk registers and 
ongoing monitoring of key risks and mitigating actions; 
 
- appropriately qualified and experienced personnel; 
 
- governance team responsible for key controls testing; 
 
- key managers formally evaluating the satisfactory and effective operation of 
financial and operational controls; 
 
- internal auditors testing management's implementation of their 
recommendations following audit reviews, to include IT audit reviews of system 
access controls; 
 
- external auditors providing advice on specific accounting matters; and 
 
- a confidential helpline service to provide staff with a confidential, and if 
required, anonymous means to report fraud or ethical concerns. 
 
The Board, supported by the Audit & Risk Committee, has reviewed the 
effectiveness of the system of internal control. 
 
Directors' Insurance 
 
Insurance in respect of directors' and officers' liability is maintained by the 
Company's ultimate parent, ESB. 
 
Disclosure of Information to the Auditors 
 
So far as each person who was a director at the date of approving this report 
is aware, there is no relevant audit information, being information needed by 
the auditors in connection with preparing their report, of which the auditors 
are unaware.  Having made enquiries of fellow directors and the Group's 
auditors, each director has taken all the steps that he/she is obliged to take 
as a director in order to make himself/herself aware of any relevant audit 
information and to establish that the auditors are aware of that information. 
 
Appointment of Auditors 
 
Following the Board's appointment of PricewaterhouseCoopers LLP (PwC) as 
external auditors of the Company and Group in July 2017, PwC have indicated 
their willingness to continue in office and a resolution that they be 
re-appointed will be proposed to the shareholder during the period for 
appointing auditors. 
 
Modern Slavery Act 
 
Modern slavery is a criminal offence under the Modern Slavery Act 2015.  The 
Act imposes obligations on organisations of a certain size.  Modern Slavery can 
occur in various forms, including servitude, forced and compulsory labour and 
human trafficking, all of which have in common the deprivation of a person's 
liberty by another in order to exploit them for personal or commercial gain. 
NIE Networks has adopted a Policy on Modern Slavery with the aim of preventing 
opportunities for modern slavery occurring within its business and supply 
chains.  In accordance with the requirements of the Act, NIE Networks publishes 
a statement on its website on slavery and human trafficking. 
 
Political Donations 
 
No donations for political purposes have been made during the year (2016 - GBP 
nil). 
 
Group Strategic Report 
 
The following information required in the Group Directors' Report has been 
included in the Group Strategic Report: 
 
- an indication of future developments in the business (see pages 4 - 14); 
 
- the Group's objectives and policies for financial risk management (including 
liquidity risk and credit risk) (see pages 6 - 8); 
 
- a statement on the policy for disabled employees (see page 13); 
 
- arrangements for employees to participate in the affairs of the Group (see 
pages 13 - 14); and 
 
- an indication of activities in the Group in the field of research and 
development (see page 11). 
 
Directors' Responsibilities Statement 
 
The directors are responsible for preparing the Annual Report and the financial 
statements in accordance with applicable laws and regulations. 
 
Company law requires the directors to prepare financial statements for each 
financial year. Under that law the directors have prepared the Group financial 
statements in accordance with International Financial Reporting Standards 
(IFRSs) as adopted by the European Union and Company financial statements in 
accordance with United Kingdom Generally Accepted Accounting Practice (United 
Kingdom Accounting Standards, comprising FRS 101 "Reduced Disclosure 
Framework", and applicable law). 
 
Under company law the directors must not approve the financial statements 
unless they are satisfied that they give a true and fair view of the state of 
affairs of the Group and Company and of the profit or loss of the Group and 
Company for that period. In preparing the financial statements, the directors 
are required to: 
 
- select suitable accounting policies and then apply them consistently; 
 
- state whether applicable IFRS as adopted by the European Union have been 
followed for the Group financial statements and United Kingdom Accounting 
Standards, comprising FRS 101, have been followed for the Company financial 
statements, subject to any material departures disclosed and explained in the 
financial statements; 
 
- make judgements and accounting estimates that are reasonable and prudent; and 
 
- prepare the financial statements on the going concern basis unless it is 
inappropriate to presume that the Group and Company will continue in business. 
 
The directors are responsible for keeping adequate accounting records that are 
sufficient to show and explain the Group and Company's transactions and 
disclose with reasonable accuracy at any time the financial position of the 
Group and Company and enable them to ensure that the financial statements 
comply with the Companies Act 2006 and, as regards the Group financial 
statements, Article 4 of the IAS Regulation. 
 
The directors are also responsible for safeguarding the assets of the Group and 
Company and hence for taking reasonable steps for the prevention and detection 
of fraud and other irregularities. 
 
The directors are responsible for the maintenance and integrity of the 
Company's website. Legislation in the United Kingdom governing the preparation 
and dissemination of financial statements may differ from legislation in other 
jurisdictions.

INDEPENT AUDITORS' REPORT 
 
to the members of Northern Ireland Electricity Networks Limited 
 
Report on the audit of the financial statements 
 
Opinion 
 
In our opinion: 
 
- Northern Ireland Electricity Networks Limited's group financial statements 
and company financial statements (the "financial statements") give a true and 
fair view of the state of the group's and of the company's affairs as at 31 
December 2017 and of the group's profit and cash flows for the year then ended; 
 
- the group financial statements have been properly prepared in accordance with 
IFRSs as adopted by the European Union; 
 
- the company financial statements have been properly prepared in accordance 
with United Kingdom Generally Accepted Accounting Practice (United Kingdom 
Accounting Standards, comprising FRS 101 "Reduced Disclosure Framework", and 
applicable law); and 
 
- the financial statements have been prepared in accordance with the 
requirements of the Companies Act 2006 and, as regards the group financial 
statements, Article 4 of the IAS Regulation. 
 
We have audited the financial statements, included within the Annual Report and 
Accounts (the "Annual Report"), which comprise: the group and parent company 
Balance sheets as at 31 December 2017; the Group income statement and group and 
company Statements of comprehensive income, the group Cash flow statement, and 
the group and company Statements of changes in equity for the year then ended; 
and the Notes to the accounts, which include a description of the significant 
accounting policies. 
 
Our opinion is consistent with our reporting to the Audit & Risk Committee. 
 
Basis for opinion 
 
We conducted our audit in accordance with International Standards on Auditing 
(UK) ("ISAs (UK)") and applicable law. Our responsibilities under ISAs (UK) are 
further described in the Auditors' responsibilities for the audit of the 
financial statements section of our report. We believe that the audit evidence 
we have obtained is sufficient and appropriate to provide a basis for our 
opinion. 
 
Independence 
 
We remained independent of the group in accordance with the ethical 
requirements that are relevant to our audit of the financial statements in the 
UK, which includes the FRC's Ethical Standard, as applicable to listed public 
interest entities, and we have fulfilled our other ethical responsibilities in 
accordance with these requirements. 
 
To the best of our knowledge and belief, we declare that non-audit services 
prohibited by the FRC's Ethical Standard were not provided to the group or the 
company. 
 
Other than those disclosed in note 4 to the financial statements, we have 
provided no non-audit services to the group or the company in the period from 1 
January 2017 to 31 December 2017.

As part of designing our audit, we determined materiality and assessed the 
risks of material misstatement in the financial statements. In particular, we 
looked at where the directors made subjective judgements, for example in 
respect of significant accounting estimates that involved making assumptions 
and considering future events that are inherently uncertain. 
 
We gained an understanding of the legal and regulatory framework applicable to 
the group and the industry in which it operates, and considered the risk of 
acts by the group which were contrary to applicable laws and regulations, 
including fraud. We designed audit procedures at group and significant 
component level to respond to the risk, recognising that the risk of not 
detecting a material misstatement due to fraud is higher than the risk of not 
detecting one resulting from error, as fraud may involve deliberate concealment 
by, for example, forgery or intentional misrepresentations, or through 
collusion. We focused on laws and regulations that could give rise to a 
material misstatement in the group and company financial statements, including, 
but not limited to, the Companies Act 2006, the Listing Rules, the requirements 
of the Northern Ireland Utility Regulator. Our tests included, but were not 
limited to, review of the financial statement disclosures to underlying 
supporting documentation, review of correspondence with and reports to the 
regulators, review of correspondence with legal advisors, enquiries of 
management, review of significant component auditors' work and review of 
internal audit reports in so far as they related to the financial statements. 
There are inherent limitations in the audit procedures described above and the 
further removed non-compliance with laws and regulations is from the events and 
transactions reflected in the financial statements, the less likely we would 
become aware of it. 
 
We did not identify any key audit matters relating to irregularities, including 
fraud. As in all of our audits we also addressed the risk of management 
override of internal controls, including testing journals and evaluating 
whether there was evidence of bias by the directors that represented a risk of 
material misstatement due to fraud. 
 
Key audit matters 
 
Key audit matters are those matters that, in the auditors' professional 
judgement, were of most significance in the audit of the financial statements 
of the current period and include the most significant assessed risks of 
material misstatement (whether or not due to fraud) identified by the auditors, 
including those which had the greatest effect on: the overall audit strategy; 
the allocation of resources in the audit; and directing the efforts of the 
engagement team. These matters, and any comments we make on the results of our 
procedures thereon, were addressed in the context of our audit of the financial 
statements as a whole, and in forming our opinion thereon, and we do not 
provide a separate opinion on these matters. This is not a complete list of all 
risks identified by our audit.

                                            We concluded that unbilled revenue was

How we tailored the audit scope 
 
We tailored the scope of our audit to ensure that we performed enough work to 
be able to give an opinion on the financial statements as a whole, taking into 
account the structure of the group and the company, the accounting processes 
and controls, and the industry in which they operate. 
 
This was the first year of appointment of PwC.  As part of our procedures to 
prepare as incoming auditor and enable the development of our Audit Strategy, 
as well as meeting with management, we attended Audit & Risk Committee meetings 
throughout the year, reviewed our predecessor's working papers, engaged with 
Internal Audit and performed interim review work. 
 
We tailored the scope of our audit to ensure that we performed enough work to 
be able to give an opinion on the financial statements as a whole, taking into 
account the structure of the group and the company, the accounting processes 
and controls, and the industry in which they operate. 
 
The Northern Ireland Electricity Networks Limited Group comprises of Northern 
Ireland Electricity Networks Limited, NIE Finance PLC and NIE Networks Services 
Limited. All companies are financially significant to the group and therefore 
required an audit of their complete financial information. 
 
As part of designing our audit, we determined materiality and assessed the 
risks of material misstatement in the financial statements. In particular, we 
looked at where the directors made subjective judgements, for example in 
respect of significant accounting estimates that involved making assumptions 
and considering future events that are inherently uncertain. As in all of our 
audits we also addressed the risk of management override of internal controls, 
including evaluating whether there was evidence of bias by the directors that 
represented a risk of material misstatement due to fraud. 
 
Materiality 
 
The scope of our audit was influenced by our application of materiality. We set 
certain quantitative thresholds for materiality. These, together with 
qualitative considerations, helped us to determine the scope of our audit and 
the nature, timing and extent of our audit procedures on the individual 
financial statement line items and disclosures and in evaluating the effect of 
misstatements, both individually and in aggregate on the financial statements 
as a whole. 
 
Based on our professional judgement, we determined materiality for the 
financial statements as a whole as follows: 
 
                         Group financial statements      Company financial statements 
 
Overall materiality   GBP2,650,000                       GBP2,550,000 
 
How we determined it  5% of profit before tax.         5% of profit before tax. 
 
Rationale for         Based on the benchmarks used in  We believe that profit before

                      tax is the primary measure used  by the shareholders in assessing

                      the performance of the group,    and is a generally accepted 
                      and is a generally accepted      auditing benchmark.  The 
                      auditing benchmark.              benchmark was adjusted to comply 
                                                       with ISA (UK) 600 which requires 
                                                       component materiality to be 
                                                       lower than overall group 
                                                       materiality. 
 
For each component in the scope of our group audit, we allocated a materiality 
that is less than our overall group materiality. The range of materiality 
allocated across components was between GBP93,980 and GBP2,550,000. Certain 
components were audited to a local statutory audit materiality that was also 
less than our overall group materiality. 
 
We agreed with the Audit & Risk Committee that we would report to them 
misstatements identified during our audit above GBP132,500 (Group and Company 
audit) as well as misstatements below those amounts that, in our view, 
warranted reporting for qualitative reasons. 
 
Conclusions relating to going concern 
 
We have nothing to report in respect of the following matters in relation to 
which ISAs (UK) require us to report to you when: 
 
- the directors' use of the going concern basis of accounting in the 
preparation of the financial statements is not appropriate; or 
 
- the directors have not disclosed in the financial statements any identified 
material uncertainties that may cast significant doubt about the group's and 
company's ability to continue to adopt the going concern basis of accounting 
for a period of at least twelve months from the date when the financial 
statements are authorised for issue. 
 
However, because not all future events or conditions can be predicted, this 
statement is not a guarantee as to the group's and company's ability to 
continue as a going concern. 
 
Reporting on other information 
 
The other information comprises all of the information in the Annual Report 
other than the financial statements and our auditors' report thereon. The 
directors are responsible for the other information. Our opinion on the 
financial statements does not cover the other information and, accordingly, we 
do not express an audit opinion or, except to the extent otherwise explicitly 
stated in this report, any form of assurance thereon. 
 
In connection with our audit of the financial statements, our responsibility is 
to read the other information and, in doing so, consider whether the other 
information is materially inconsistent with the financial statements or our 
knowledge obtained in the audit, or otherwise appears to be materially 
misstated. If we identify an apparent material inconsistency or material 
misstatement, we are required to perform procedures to conclude whether there 
is a material misstatement of the financial statements or a material 
misstatement of the other information. If, based on the work we have performed, 
we conclude that there is a material misstatement of this other information, we 
are required to report that fact. We have nothing to report based on these 
responsibilities. 
 
With respect to the Group Strategic Report and Group Directors' Report, we also 
considered whether the disclosures required by the UK Companies Act 2006 have 
been included. 
 
Based on the responsibilities described above and our work undertaken in the 
course of the audit, ISAs (UK) require us also to report certain opinions and 
matters as described below. 
 
Group Strategic Report and Group Directors' Report 
 
In our opinion, based on the work undertaken in the course of the audit, the 
information given in the Group Strategic Report and Group Directors' Report for 
the year ended 31 December 2017 is consistent with the financial statements and 
has been prepared in accordance with applicable legal requirements. 
 
In light of the knowledge and understanding of the group and company and their 
environment obtained in the course of the audit, we did not identify any 
material misstatements in the Group Strategic Report and Group Directors' 
Report. 
 
Responsibilities for the financial statements and the audit 
 
Responsibilities of the directors for the financial statements 
 
As explained more fully in the Statement of Directors' Responsibilities set out 
on page 26, the directors are responsible for the preparation of the financial 
statements in accordance with the applicable framework and for being satisfied 
that they give a true and fair view. The directors are also responsible for 
such internal control as they determine is necessary to enable the preparation 
of financial statements that are free from material misstatement, whether due 
to fraud or error. 
 
In preparing the financial statements, the directors are responsible for 
assessing the group's and the company's ability to continue as a going concern, 
disclosing as applicable, matters related to going concern and using the going 
concern basis of accounting unless the directors either intend to liquidate the 
group or the company or to cease operations, or have no realistic alternative 
but to do so. 
 
Auditors' responsibilities for the audit of the financial statements 
 
Our objectives are to obtain reasonable assurance about whether the financial 
statements as a whole are free from material misstatement, whether due to fraud 
or error, and to issue an auditors' report that includes our opinion. 
Reasonable assurance is a high level of assurance, but is not a guarantee that 
an audit conducted in accordance with ISAs (UK) will always detect a material 
misstatement when it exists. Misstatements can arise from fraud or error and 
are considered material if, individually or in the aggregate, they could 
reasonably be expected to influence the economic decisions of users taken on 
the basis of these financial statements. 
 
A further description of our responsibilities for the audit of the financial 
statements is located on the FRC's website at: www.frc.org.uk/ 
auditorsresponsibilities. This description forms part of our auditors' report. 
 
Use of this report 
 
This report, including the opinions, has been prepared for and only for the 
company's members as a body in accordance with Chapter 3 of Part 16 of the 
Companies Act 2006 and for no other purpose. We do not, in giving these 
opinions, accept or assume responsibility for any other purpose or to any other 
person to whom this report is shown or into whose hands it may come save where 
expressly agreed by our prior consent in writing. 
 
Other required reporting 
 
Companies Act 2006 exception reporting 
 
Under the Companies Act 2006 we are required to report to you if, in our 
opinion: 
 
- we have not received all the information and explanations we require for our 
audit; or 
 
- adequate accounting records have not been kept by the company, or returns 
adequate for our audit have not been received from branches not visited by us; 
or 
 
- certain disclosures of directors' remuneration specified by law are not made; 
or 
 
- the company financial statements are not in agreement with the accounting 
records and returns. 
 
We have no exceptions to report arising from this responsibility. 
 
Appointment 
 
Following the recommendation of the Audit & Risk Committee, we were appointed 
by the Board on 17 October 2017 to audit the financial statements for the year 
ended 31 December 2017 and subsequent financial periods. This is therefore our 
first year of uninterrupted engagement.

NOTES TO THE ACCOUNTS 
 
1. General Information 
 
Northern Ireland Electricity Networks Limited (NIE Networks or the Company) is 
a limited company incorporated, domiciled and registered in Northern Ireland 
(registered number NI026041).  The Company's registered office address is 120 
Malone Road, Belfast, BT9 5HT.  The principal activities of the Company are 
described in the Group Strategic Report. 
 
2. Accounting Policies 
 
The principal accounting policies applied in the preparation of these accounts 
are set out below. These policies have been applied consistently to all years 
presented, unless otherwise stated. 
 
New and revised accounting standards, amendments and interpretations 
 
No new standards, amendments or interpretations, effective for the first time 
for the financial year beginning on or after 1 January 2017, have had a 
material impact on the financial statements of the Group or the Company. 
 
New and revised accounting standards, amendments and interpretations not yet 
adopted 
 
A number of new standards and amendments to standards and interpretations are 
effective for annual periods beginning after 1 January 2017, and have not been 
applied in preparing these financial statements. None of these is expected to 
have a significant effect on the financial statements of the Group or Company. 
The more significant future accounting standards and how they may apply to the 
Group and Company is discussed below: 
 
IFRS 9, 'Financial instruments' 
 
IFRS 9 addresses the classification, measurement and recognition of financial 
assets and financial liabilities. It replaces the guidance in IAS 39 that 
relates to the classification and measurement of financial instruments. 
 
IFRS 9 retains but simplifies the mixed measurement model and establishes three 
primary measurement categories for financial assets: amortised cost; fair value 
through other comprehensive income; and fair value through profit or loss. The 
basis of classification depends on the entity's business model and the 
contractual cash flow characteristics of the financial asset. An expected 
credit losses model replaces the incurred loss impairment model used in IAS 39. 
 
For financial liabilities, there are no changes to classification and 
measurement, except for the recognition of changes in own credit risk in other 
comprehensive income, for liabilities designated at fair value through profit 
or loss. 
 
IFRS 9 is effective for accounting periods beginning on or after 1 January 
2018. Early adoption is permitted. 
 
The Group is working towards the implementation of IFRS 9 on 1 January 2018. It 
anticipates that the classification and measurement basis for its financial 
assets and liabilities will be largely unchanged by the adoption of IFRS 9. 
 
The main impact of adopting IFRS 9 is likely to arise from the implementation 
of the expected credit losses model however, due to the Group's limited 
exposure to credit risk in respect of its trade receivables (see note 13) the 
Group does not expect that this will have a material impact on the financial 
statements of the Group or Company. 
 
IFRS 15, 'Revenue from contracts with customers' 
 
IFRS 15 deals with revenue recognition and establishes principles for reporting 
useful information to users of financial statements about the nature, amount, 
timing and uncertainty of revenue and cash flows arising from an entity's 
contracts with customers. Revenue is recognised when a customer obtains control 
of a good or service and thus has the ability to direct the use and obtain the 
benefits from the good or service. 
 
The standard replaces IAS 18, 'Revenue', and IAS 11, 'Construction contracts', 
and related interpretations. The standard is effective for annual periods 
beginning on or after 1 January 2018, and earlier application is permitted. 
 
The Group is working towards the implementation of IFRS 15 on 1 January 2018 
and has carried out a review of existing contractual arrangements as part of 
this process. The directors anticipate that there will be no material impact in 
respect of revenue derived from distribution use of system tariffs, PSO charges 
and transmission service charges. 
 
In respect of revenue earned through charges for new connections to the 
network, the directors anticipate a change in the timing of recognition in 
respect of some elements of connections revenue, however it is anticipated that 
this change will have no impact on the future operating profit of the Group or 
Company. 
 
IFRS 16, 'Leases' 
 
IFRS 16 addresses the definition of a lease, recognition and measurement of 
leases, and it establishes principles for reporting useful information to users 
of financial statements about the leasing activities of both lessees and 
lessors. A key change arising from IFRS 16 is that most operating leases will 
be accounted for on balance sheet for lessees. 
 
The standard replaces IAS 17, 'Leases', and related interpretations. The 
standard is effective for annual periods beginning on or after 1 January 2019, 
and earlier application is permitted, subject to EU endorsement and the entity 
adopting IFRS 15, 'Revenue from contracts with customers', at the same time. 
 
The Group continues to assess the impact of IFRS 16 on the financial statements 
of the Group and Company. At this stage, the directors anticipate that the 
adoption of IFRS 16 may result in changes in the presentation of the Group's 
and Company's accounts from 2019. 
 
Basis of Preparation 
 
The Group accounts have been prepared in accordance with International 
Financial Reporting Standards (IFRS) and IFRS Interpretations Committee (IFRIC) 
interpretations as adopted by the EU and applied in accordance with the 
provisions of the Companies Act 2006 as applicable to companies reporting under 
IFRS. 
 
The Company accounts have been prepared in accordance with Financial Reporting 
Standard 101 Reduced Disclosure Framework (FRS 101) and in accordance with 
applicable accounting standards. 
 
The financial statements of the Group and Company have been prepared under the 
historical cost convention, as modified by the revaluation of derivative 
instruments at fair value through profit or loss. 
 
The accounts are presented in Sterling (GBP) with all values rounded to the 
nearest GBP100,000 except where otherwise indicated. 
 
The Company has taken advantage of the following disclosure exemptions under 
FRS 101: 
 
a) the requirements of paragraphs 10(d), 38A, 38B, 38C, 38D, 40A, 40B, 40C, 
40D, 111 and 134-136 of IAS 1 Presentation of Financial Statements, which are 
requirements relating to cash flows, comparative information, statement of 
compliance and the management of capital; 
 
b) the requirements of IAS 7 Statement of Cash Flows in preparing a cash flow 
statement for the Company; 
 
c) the requirements of paragraphs 17 and 18A of IAS 24 Related Party 
Disclosures relating to the disclosure of key management personnel 
compensation; and 
 
d) the requirements in IAS 24 Related Party Disclosures to disclose related 
party transactions entered into between two or more members of a group, 
provided that any subsidiary which is a party to the transaction is wholly 
owned by such a member. 
 
Basis of Preparation - Going Concern 
 
The Group is financed through a combination of equity and debt finance. 
Details in respect of the Group's equity are shown in the Statement of Changes 
in Equity and in note 22 to the accounts.  The Group's debt finance at the year 
end comprised bonds of GBP175.0m and GBP400.0m (GBP174.8m and GBP398.5m respectively 
net of issue costs) which are due to mature in September 2018 and June 2026 
respectively and GBP114.0m drawn down from a GBP150.0m RCF from ESB which is due to 
mature in September 2018. 
 
The Group's liquidity risk is assessed through the preparation of cash flow 
forecasts.  The Group's policy is to have sufficient funds in place to meet 
funding requirements for the next 12 - 18 months. In light of the maturity of 
the GBP175.0m bond and GBP150.0m RCF in September 2018, the Group is currently 
assessing longer term financing options in conjunction with its parent, ESB. 
The Group is satisfied that it will have access to funds in advance of the 
maturity of existing facilities as it has secured an option to extend the 
existing GBP150.0m RCF from ESB to GBP400.0m with maturity deferred until March 
2019. 
 
On the basis of their assessment of the Group's financial position, which 
included a review of the Group's projected funding requirements for a period of 
12 months from the date of approval of the accounts and consideration of the 
option to extend and increase the existing RCF from ESB, the directors have a 
reasonable expectation that the Group will have adequate financial resources 
for the 12 month period. Accordingly the directors continue to adopt the going 
concern basis in preparing the annual report and accounts. 
 
Basis of consolidation 
 
The Group accounts consolidate the accounts of the Company and entities 
controlled by the Company (its subsidiaries), NIE Networks Services Limited and 
NIE Finance PLC.  Control exists when the Company is exposed to, or has the 
rights to, variable returns from its involvement with an entity and has the 
ability to affect those returns through its power, directly or indirectly, to 
govern the financial and operating policies of the entity. In assessing 
control, potential voting rights that presently are exercisable or convertible 
are taken into account. Subsidiaries are consolidated from the day on which 
control is transferred to the Group and cease to be consolidated from the date 
on which control is transferred out of the Group. 
 
All intra-Group transactions, balances, income and expenses are eliminated on 
consolidation. 
 
Company's investments in subsidiaries 
 
The Company recognises its investments in subsidiaries at cost less any 
recognised impairment loss. Dividends received from subsidiaries are recognised 
in the income statement.  The carrying values of investments in subsidiaries 
are reviewed annually for any indications of impairment, including whether the 
carrying value is impaired as a result of the receipt of dividends. 
 
Property, plant and equipment 
 
Property, plant and equipment are included in the balance sheet at cost, less 
accumulated depreciation and any recognised impairment loss.  The cost of 
self-constructed assets includes the cost of materials, direct labour and an 
appropriate portion of overheads.  Interest on funding attributable to 
significant capital projects is capitalised during the period of construction 
provided it meets the recognition criteria in IAS 23 and is written off as part 
of the total cost of the asset. 
 
Freehold land is not depreciated.  Other property, plant and equipment are 
depreciated on a straight-line basis so as to write off the cost, less 
estimated residual values, over their estimated useful economic lives as 
follows: 
 
Infrastructure assets - up to 40 years 
 
Non-operational buildings - freehold and long leasehold - up to 60 years 
 
Fixtures and equipment - up to 10 years 
 
Vehicles and mobile plant - up to 5 years 
 
The carrying values of property, plant and equipment are reviewed for 
impairment when events or changes in circumstances indicate the carrying value 
may not be recoverable.  Where the carrying value exceeds the estimated 
recoverable amount, the asset is written down to its recoverable amount. 
 
The recoverable amount of property, plant and equipment is the greater of net 
selling price and value in use.  In assessing value in use, estimated future 
cash flows are discounted to their present value using a pre-tax discount rate 
that reflects current market assessments of the time value of money and the 
risks specific to the asset.  For an asset that does not generate largely 
independent cash flows, the recoverable amount is determined for the cash 
generating unit to which the asset belongs.  Impairment losses are recognised 
in the income statement. 
 
An item of property, plant and equipment is derecognised upon disposal or when 
no future economic benefits are expected to arise from its continued use.  The 
gain or loss arising on the disposal or retirement of an asset is determined as 
the difference between the net selling price and the carrying amount of the 
asset. 
 
Intangible assets - Computer software 
 
The cost of acquiring computer software is capitalised and amortised on a 
straight-line basis over its estimated useful economic life which is between 
three and ten years.  Costs include direct labour relating to software 
development and an appropriate portion of directly attributable overheads. 
Interest on funding attributable to significant capital projects is capitalised 
during the period of construction provided it meets the recognition criteria in 
IAS 23 and is written off as part of the total cost of the asset. 
 
The carrying value of computer software is reviewed for impairment annually 
when the asset is not yet in use and subsequently when events or changes in 
circumstances indicate that the carrying value may not be recoverable. 
 
Gains or losses arising from de-recognition of computer software are measured 
as the difference between the net selling price and the carrying amount of the 
asset. 
 
Inventories 
 
Inventories are stated at the lower of cost and net realisable value. Cost is 
calculated as the weighted average purchase price. Net realisable value is the 
estimated selling price in the ordinary course of business less the estimated 
costs of completion and the estimated costs necessary to make the sale. 
 
Financial instruments 
 
The accounting policies for the financial instruments of the Group are set out 
below. The related objectives and policies for financial risk management 
(including capital management and liquidity risk, credit risk and interest rate 
risk) are included in the Group Strategic report. 
 
Cash and cash equivalents 
 
Cash and cash equivalents comprise cash at bank and in hand and short-term 
deposits with maturities of three months or less. 
 
Loans and receivables 
 
Loans and receivables are initially recorded at fair value.  After initial 
recognition, loans and receivables are measured at amortised cost using the 
effective interest method. 
 
Interest bearing loans and overdrafts 
 
Interest bearing loans and overdrafts are initially recorded at fair value, 
being the proceeds received net of direct issue costs.  After initial 
recognition, interest bearing loans are subsequently measured at amortised cost 
using the effective interest method. 
 
Trade and other receivables 
 
Trade receivables do not carry any interest and are recognised and carried at 
the lower of their amortised cost value and recoverable amount.  Provision is 
made when there is objective evidence that the asset is impaired.  Balances are 
written off when the probability of recovery is assessed as being remote. 
 
Trade payables 
 
Trade payables are not interest bearing and are stated at their amortised cost. 
 
Derivative financial instruments 
 
Derivatives that are not designated as hedging instruments are accounted for at 
'fair value through profit or loss'.  These derivatives are carried in the 
balance sheet at fair value, with changes in fair value recognised in net 
finance costs in the income statement. 
 
Borrowing costs 
 
Borrowing costs attributable to significant capital projects are capitalised as 
part of the cost of the respective qualifying assets.  All other borrowing 
costs are expensed in the period they occur.  Borrowing costs consist of 
interest and other costs that an entity incurs in connection with the borrowing 
of funds. 
 
Operating lease contracts 
 
Leases are classified as operating lease contracts whenever the terms of the 
lease do not transfer substantially all the risks and benefits of ownership to 
the lessee. 
 
Rentals payable under operating leases are charged to the income statement on a 
straight-line basis over the lease term. 
 
Revenue 
 
Revenue is recognised to the extent that it is probable that the economic 
benefits will flow to the Group and the revenue can be reliably measured. 
Revenue is measured at the fair value of the consideration received or 
receivable and represents amounts receivable for services provided in the 
normal course of business, exclusive of value added tax and other sales related 
taxes. 
 
The following specific recognition criteria must also be met before revenue is 
recognised: 
 
Interest receivable 
 
Interest income is accrued on a time basis, by reference to the principal 
outstanding and at the effective interest rate applicable, which is the rate 
that exactly discounts estimated future cash receipts through the expected life 
of the financial asset to that asset's net carrying amount. 
 
Use of System and PSO revenue 
 
Revenue is recognised on the basis of units distributed during the period. 
Revenue includes an assessment of the volume of electricity distributed, 
estimated using historical consumption patterns. 
 
Transmission service revenue 
 
Revenue is recognised in accordance with the schedule of entitlement set by the 
Utility Regulator for each tariff period. 
 
Customer contributions 
 
Customer contributions received in respect of property, plant and equipment are 
deferred and released to revenue in the income statement by instalments over 
the estimated useful economic lives of the related assets. 
 
Government grants 
 
Government grants received in respect of property, plant and equipment are 
deferred and released to operating costs in the income statement by instalments 
over the estimated useful economic lives of the related assets.  Grants 
received in respect of expenditure charged to the income statement during the 
period are included in the income statement. 
 
Tax 
 
The tax charge represents the sum of tax currently payable and deferred tax. 
Tax is charged or credited in the income statement, except when it relates to 
items charged or credited directly to equity, in which case the tax is also 
dealt with in equity. 
 
Tax currently payable is based on taxable profit for the period.  Taxable 
profit differs from net profit as reported in the income statement because it 
excludes both items of income or expense that are taxable or deductible in 
other years as well as items that are never taxable or deductible.  The Company 
and Group's liability for current tax is calculated using tax rates (and tax 
laws) that have been enacted or substantially enacted by the balance sheet 
date. 
 
Deferred tax is the tax payable or recoverable on differences between the 
carrying amount of assets and liabilities in the accounts and the corresponding 
tax bases used in the computation of taxable profit, and is accounted for using 
the balance sheet liability method.  Deferred tax liabilities are generally 
recognised for all taxable temporary differences and deferred tax assets are 
recognised to the extent that it is probable that taxable profits will be 
available against which deductible temporary differences can be utilised. 
 
Deferred tax liabilities are recognised for taxable temporary differences 
arising on investments in subsidiaries, except where the Group is able to 
control the reversal of the temporary difference and it is probable that the 
temporary difference will not reverse in the foreseeable future. 
 
Deferred tax is not recognised on temporary differences where they arise from 
the initial recognition of goodwill or of an asset or liability in a 
transaction that is not a business combination that at the time of the 
transaction affects neither accounting nor taxable profit nor loss. 
 
The carrying amount of deferred tax assets is reviewed at each balance sheet 
date and reduced to the extent that it is no longer probable that sufficient 
taxable profits will be available to allow all or part of the deferred tax 
asset to be recovered. 
 
Deferred tax assets and liabilities are calculated at the tax rates that are 
expected to apply to the period when the asset is realised or the liability is 
settled, based on tax rates (and tax laws) that have been enacted or 
substantially enacted by the balance sheet date. 
 
Provisions 
 
Provisions are recognised when (i) the Group has a present obligation (legal or 
constructive) as a result of a past event (ii) it is probable that an outflow 
of resources embodying economic benefits will be required to settle the 
obligation and (iii) a reliable estimate can be made of the amount of the 
obligation.  Where the Group expects a provision to be reimbursed, the 
reimbursement is recognised as a separate asset but only when the reimbursement 
is virtually certain.  If the effect of the time value of money is material, 
provisions are determined by discounting the expected future cash flows at a 
pre-tax rate that reflects current market assessments of the time value of 
money and, where appropriate, the risks specific to the liability.  Where 
discounting is used, the increase in the provision due to the passage of time 
is included within finance costs. 
 
Pensions and other post-retirement benefits 
 
Employees of the Group are entitled to membership of the Northern Ireland 
Electricity Pension Scheme (NIEPS) which has both defined benefit and defined 
contribution pension arrangements.  The amount recognised in the balance sheet 
in respect of liabilities represents the present value of the obligations 
offset by the fair value of assets. 
 
Pension scheme assets are measured at fair value and liabilities are measured 
using the projected unit credit method and discounted at a rate equivalent to 
the current rate of return on a high quality corporate bond of equivalent 
currency and term to the liabilities.  Full actuarial valuations are obtained 
at least triennially and updated at each balance sheet date.  Re-measurements 
comprising of actuarial gains and losses and return on plan assets are 
recognised immediately in the period in which they occur and are presented in 
the statement of comprehensive income. Re-measurements are not reclassified to 
profit or loss in subsequent periods. 
 
The cost of providing benefits under the defined benefit scheme is charged to 
the income statement over the periods benefiting from employees' service. 
These costs comprise current service costs, past service costs, gains or losses 
on curtailments and non-routine settlements, all of which are recognised in 
operating costs. Past service costs are recognised immediately to the extent 
that the benefits are already vested.  Curtailment losses are recognised in the 
income statement in the period they occur. 
 
Net pension interest on net pension scheme liabilities is included within net 
finance costs. Net interest is calculated by applying the discount rate to the 
net pension asset or liability. 
 
Pension costs in respect of defined contribution arrangements are charged to 
the income statement as they become payable. 
 
The Group has adopted the exemption allowed in IFRS 1 to recognise all 
cumulative actuarial gains and losses at the transition date in reserves. 
 
Critical accounting judgements and key sources of estimation uncertainty 
 
Pensions and other post-employment benefits 
 
The employees in NIE Networks are entitled to membership of the NIEPS which has 
both defined benefit and defined contribution arrangements. The estimation of 
and accounting for retirement benefit obligations involves judgements made in 
conjunction with independent actuaries. This involves estimates about uncertain 
future events including the life expectancy of scheme members, future salary 
and pension increases and inflation as well as discount rates. The assumptions 
used by the Group and a sensitivity analysis of a change in these assumptions 
are described in note 21. 
 
Unbilled debt 
 
Revenue includes an assessment of the volume of electricity distributed, 
estimated using historical consumption patterns.  A corresponding receivable in 
respect of unbilled consumption is recognised within trade receivables. 
 
Fair value measurement 
 
The measurement of the Group's derivative financial instruments is based on a 
number of judgmental factors and assumptions which by necessity are not based 
on observable inputs.  These have been classified as Level 2 financial 
instruments in accordance with IFRS 13.  Further detail is provided in note 17.

The credit quality of trade receivables that are neither past due nor impaired 
is assessed by reference to external credit ratings where available, otherwise 
historical information relating to counterparty default rates is used.  The 
directors consider that the carrying amount of trade and other receivables 
approximates to fair value. 
 
The Group's credit risk in respect of trade receivables from licensed

The Company has held a GBP550m portfolio of inflation linked interest rate swaps 
(the RPI swaps) since December 2010.  The fair value of inflation linked 
interest rate swaps is affected by relative movements in interest rates and 
market expectations of future retail price index (RPI) movements. 
 
The RPI swaps were put in place by the Viridian Group (the Group's previous 
parent undertaking) in 2006 to better match NIE Networks' debt and related 
interest payments with its inflation-linked regulated assets and associated 
revenue. The swaps are considered to be economic hedges for NIE Networks' 
regulated revenue and asset base. As part of the acquisition of NIE Networks by 
ESB in 2010, the swaps were novated to NIE Networks. 
 
During 2014 the Company, and its counterparty banks, together agreed a 
restructuring of the swaps, including amendments to certain critical terms. 
These changes included an extension of the mandatory break period in the swaps 
from 2015 to 2022, including immediate settlement of accretion payments of GBP 
77.7m (previously due for payment in 2015), amendments to the fixed interest 
rate element of the swaps and an increase in the number of swap counterparties. 
 Future accretion payments are now scheduled to occur every 5 years, starting 
in 2018, with remaining accretion paid on maturity. 
 
Arising from lower forward interest rates and higher RPI forward prices during 
the year, positive fair value movements of GBP3.8m occurred in 2017 (2016 - 
negative fair value movements of GBP145.4m). These have been recognised in 
finance costs in the income statement. 
 
The increase in the current portion of the interest rate swaps in 2017 is 
largely owing to accretion payments falling due in 2018. 
 
At the same time that the restructuring took effect, and in order to maintain 
the back to back matching put in place with ESBNI Limited (ESBNI), the Company 
entered into RPI linked interest rate swap arrangements with ESBNI, the 
immediate parent undertaking of the Company, which have identical matching 
terms to the restructured swaps.  The back to back matching swaps with ESBNI 
ensure that there is no net effect on the accounts of the Company and that any 
risk to financial exposure is borne by ESBNI.  The fair value movements have 
been recognised in finance costs in the income statement effectively offsetting 
the fair value movements of interest rate swap liabilities. 
 
The fair value of interest rate swaps has been valued by calculating the 
present value of future cash flows, estimated using forward rates from third 
party market price quotations. 
 
The Company uses the hierarchy as set out in IFRS 13: Fair Value Measurement. 
All assets and liabilities for which fair value is disclosed are categorised 
within the fair value hierarchy described as follows: 
 
Level 1: quoted (unadjusted) market prices in active markets for identical 
assets or liabilities; 
 
Level 2: valuation techniques for which the lowest level input that is 
significant to the fair value measurement is directly or indirectly observable; 
and 
 
Level 3: valuation techniques for which the lowest level input that is 
significant to the fair value measurement is not observable. 
 
The fair value of interest rate swaps as at 31 December 2017 is considered by 
the Company to fall within the level 2 fair value hierarchy.  The Company 
determines whether transfers have occurred between levels in the hierarchy by 
re-assessing categorisation (based on the lowest level input that is 
significant to the fair value measurement as a whole) at the end of each 
reporting period. There have been no transfers between level 1 or 3 of the 
hierarchy during the year. 
 
Independent valuations are used in measuring the interest rate swaps and 
validated using the present valuation of expected cash flows using a 
constructed zero-coupon discount curve.  The zero-coupon curve uses the 
interest rate yield curve of the relevant currency. Future cash flows are 
estimated using expected RPI benchmark levels as well as expected LIBOR rate 
sets. 
 
An increase / (decrease) of 0.5% in interest rates would decrease / (increase) 
the fair value of interest rate swap liabilities by GBP58.1m / (GBP63.3m) (2016 - GBP 
63.8m / (GBP65.2m)).  However, the swap arrangements entered into with ESBNI 
hedge the Company's cash flows in respect of these liabilities and therefore, 
an increase / (decrease) of 0.5% in interest rates would increase / (decrease) 
the fair value of the interest rate swap assets by GBP58.1m / (GBP63.3m) (2016 - GBP 
63.8m / (GBP65.2m)) and thereby offset the exposure to the swap liabilities. 
These sensitivities are based on an assessment of market rate movements during 
the period and each is considered to be a reasonably possible range.

Other financial liabilities are held at amortised cost. 
 
The principal features of the Group's borrowings are as follows: 
 
- the GBP175m bond is repayable in September 2018 and carries a fixed rate of 
interest of 6.875% which is payable annually in arrears on 18 September. The 
bond issue incurred GBP2.6m of costs associated with raising finance; 
 
- the 15 year GBP400m bond is repayable in 2026 and carries a fixed rate of 
interest of 6.375% which is payable annually in arrears on 2 June.  The bond 
issue incurred GBP2.1m of costs associated with raising finance.  In back to back 
arrangements, NIE Finance PLC has a loan of GBP400m with the Company, which was 
issued net of GBP2.1m of costs associated with raising finance.  Interest is paid 
on the loan at a fixed rate of 6.375% annually in arrears on 2 June; and 
 
- amounts owed to parent undertaking represents a drawdown of GBP114.0 (2016 - GBP 
19.1m) from the Company's GBP150.0m Revolving Credit Facility (RCF) provided by 
ESB which has a maturity date of September 2018. Interest is charged at 1-month 
LIBOR plus 0.75% and paid in arrears on the following draw-down date. 
Commitment fees are charged on the undrawn element of the facility. 
 
The GBP175m and GBP400m bonds, which are listed on the London Stock Exchange's 
regulated market, had fair values at 31 December 2017 of GBP182.3m (2016 - GBP 
194.0m) and GBP545.3m (2016 - GBP553.6m) respectively, based on current market 
prices.  The Company's GBP400m back-to-back loan had a fair value at 31 December 
2017 of GBP545.3m (2016 - GBP553.6m) based on the fair value of the GBP400m bond. 
 
The fair value of bonds as at 31 December 2017 is considered by the Company to 
fall within the level 1 fair value hierarchy (defined within note 17).  There 
have been no transfers between levels in the hierarchy during the year. 
 
Given that 83% (2016 - 97%) of the Group and Company borrowings carry fixed 
interest rates, the Group and Company were not significantly exposed to 
movements in interest rates during the year.

Environment 
 
Provision has been made for expected costs of decontamination and demolition 
arising from obligations in respect of power station sites formerly owned by 
the Group.  It is anticipated that the expenditure relating to the non-current 
portion of the provision will take place within the next five years. 
 
Liability and damage claims 
 
Notwithstanding the intention of the directors to defend vigorously claims made 
against the Group, liability and damage claim provisions have been made which 
represent the directors' best estimate of costs expected to arise from ongoing 
third party litigation matters and employee claims.  The non current element of 
these provisions is expected to be utilised within a period not exceeding five 
years. 
 
21. Pension Commitments 
 
Most employees of the Group are members of Northern Ireland Electricity Pension 
Scheme (NIEPS or the scheme).  The scheme has two sections: 'Options' which is 
a money purchase arrangement whereby the Group generally matches the members' 
contributions up to a maximum of 7% of salary and 'Focus' which provides 
benefits based on pensionable salary at retirement or earlier exit from 
service.  The assets of the scheme are held under trust and invested by the 
trustees on the advice of professional investment managers.  The trustees are 
required by law to act in the interest of all relevant beneficiaries and are 
responsible for the investment policy with regard to the assets and the 
day-to-day administration of the benefits. 
 
Under the scheme, employees are entitled to annual pensions on retirement at 
age 63 (for members who joined after 1 April 1988) of one-sixtieth of final 
pensionable salary for each year of service.  Benefits are also payable on 
death and following events such as withdrawing from active service. 
 
UK legislation requires that pension schemes are funded prudently.  The last 
funding valuation of the scheme was carried out by a qualified actuary as at 31 
March 2014 and showed a deficit of GBP110.7m. The formal valuation as at 31 March 
2017 is currently ongoing. The Company is paying deficit contributions of GBP 
16.7m per annum (increasing in line with inflation) from 1 April 2015.  The 
Company also pays contributions of 36.6% of pensionable salaries in respect of 
current accrual, with active members paying a further 6% of pensionable 
salaries. 
 
Profile of the scheme 
 
The net liability includes benefits for current employees, former employees and 
current pensioners.  Broadly, about 21% of the liabilities are attributable to 
current employees, 5% to former employees and 74% to current pensioners.  The 
scheme duration is an indication of the weighted average time until benefit 
payments are made.  For the NIEPS, the duration is around 13 years (2016 - 13 
years) based on the last funding valuation. 
 
Risks associated with the scheme 
 
Asset volatility - liabilities are calculated using a discount rate set with 
reference to corporate bond yields.  If assets underperform this yield, this 
will create a deficit.  The scheme holds a significant proportion of growth 
assets (equities and diversified growth funds) which, though expected to 
outperform corporate bonds in the long-term, create volatility and risk in the 
short-term.  The allocation of growth assets is monitored to ensure it remains 
appropriate given the scheme's long-term objectives. 
 
Changes in bond yields - a decrease in corporate bond yields will increase the 
value placed on the scheme's liabilities for accounting purposes although this 
will be partially offset by an increase in the value of the scheme's bond 
holdings. 
 
Inflation risk - the majority of the scheme's benefit obligations are linked to 
inflation and higher inflation will lead to higher liabilities (although in 
most cases caps on the level of inflationary increases are in place to protect 
against extreme inflation).  The majority of the scheme assets are either 
unaffected by, or only loosely correlated with, inflation, meaning that an 
increase in inflation will also increase the deficit. 
 
Life expectancy - the majority of the scheme's obligations are to provide 
benefits for the life of the member, so an increase in life expectancy will 
increase the liabilities. 
 
The Company and the trustees have agreed a long-term strategy for reducing 
investment risk as and when appropriate.  This includes a liability driven 
investment policy which aims to reduce the volatility of the funding level of 
the plan by investing in assets such as index-linked gilts which perform in 
line with the liabilities of the plan so as to protect against inflation being 
higher than expected. 
 
The trustees insure certain benefits payable on death before retirement.

The curtailment loss arising in 2017 reflects past service costs associated 
with employees leaving the company under a restructuring voluntary exit 
arrangement under which 61 employees left the business during 2017. 
 
The Group expects to make contributions of approximately GBP23.3m to Focus in 
2018. 
 
The Group's share of the NIEPS service costs is allocated based on the 
pensionable payroll.  Contributions from employer, interest cost liabilities, 
interest income on assets and experience gains or losses are allocated based on 
the Group's share of the NIEPS net pension liability.

The cumulative actuarial losses recognised in the Group and Company Statements 
of Comprehensive Income since 1 April 2004 are GBP151.1m and GBP153.2m respectively 
(2016 - GBP159.3m and GBP161.4m respectively).  The directors are unable to 
determine how much of the net pension liability recognised on transition to 
IFRS and taken directly to equity is attributable to actuarial gains and losses 
since the inception of Focus.  Consequently, the directors are unable to 
determine the amount of actuarial gains and losses that would have been 
recognised in the Statement of Comprehensive Income shown before 1 April 2004.

23. Lease Obligations 
 
Property, plant and equipment 
 
The Group and Company have entered into leases on certain items of property, 
plant and equipment.  These leases contain options for renewal before the 
expiry of the lease term at rentals based on market prices at the time of 
renewal. 
 
The future minimum lease payments under non-cancellable operating leases are as 
follows: 
 
                                                                    2017            2016

                                                                  ======          ====== 
 
24. Commitments and Contingent Liabilities 
 
(i) Capital commitments 
 
At 31 December 2017 the Group and Company had contracted future capital 
expenditure in respect of property, plant and equipment of GBP8.7m (2016 - GBP 
15.3m) and computer assets of GBP3.4m (2016 - GBP1.1m). 
 
(ii) Contingent liabilities 
 
In the normal course of business the Group has contingent liabilities arising 
from claims made by third parties and employees.  Provision for a liability is 
made (as disclosed in note 20) when the directors believe that it is probable 
that an outflow of funds will be required to settle the obligation where it 
arises from an event prior to the year end. 
 
In 2014 the Lands Tribunal of Northern Ireland (the Tribunal) ruled that 
compensation was payable in respect of two out of four test cases heard by the 
Tribunal where claims were made by third parties in relation to potential 
diminution in the value of land due to the existence of electricity apparatus. 
Total compensation awarded for two of the cases was GBP45,500.  No award of 
compensation was made in the other two cases. 
 
Although the Tribunal stated that evidence of a loss of value was insufficient, 
compensation was awarded in both cases using an 'intuitive approach'.  As the 
Company knew of no precedent for the use of such an approach, the Company 
lodged an appeal to the Court of Appeal.  The appeal decision is expected in 
early 2018 and until then, it remains uncertain as to whether a liability will 
arise.  Therefore the Company has not provided for any compensation awarded by 
the Tribunal in these accounts. 
 
25. Financial Commitments 
 
In June 2011 NIE Finance PLC, a subsidiary undertaking of the Company, issued a 
GBP400m bond on behalf of the Company.  The Bond has been admitted to the 
Official List of the UK Listing Authority and to trading on the London Stock 
Exchange's regulated market.  The payments of all amounts in respect of the GBP 
400m bond are unconditionally and irrevocably guaranteed by the Company. 
 
26. Post balance sheet events 
 
On 5 February 2018, management tabled cost reduction proposals as part of a 
consultation with employee representatives which aims to reduce the number of 
job roles by 90 across the group (7% of the workforce) and align future pay 
increases with RP6 allowances. 
 
27. Related Party Disclosures
