WGL Holdings, Inc. (NYSE: WGL), through its subsidiary,
Washington Gas Energy Systems (WGESystems), announced an agreement
with Southern Company and the Electric Power Research Institute
(EPRI) to test and evaluate a battery storage system at a
1-megawatt (MW) solar array in Cedartown, Ga. The project will
analyze a 1-MW/2-MWh lithium ion battery energy storage system to
establish a technical and economic foundation for future grid
deployments, with a specific focus on renewable integration.
“The continued research and evaluation of battery storage is a
key component to increasing the feasibility of solar energy for
individuals, businesses and municipalities,” said Sanjiv Mahan,
chief operating officer of Washington Gas Energy Systems. “We are
committed to renewable energy innovation and look forward to
teaming with Southern Company and EPRI to test the battery energy
storage system in Cedartown.”
Energy storage systems provide collected electricity to the grid
on demand to compensate for the intermittence of solar, stabilizing
power output from solar arrays and other renewable energy sources.
The ground-mounted solar array consists of 3,388 solar panels with
an expected annual output of more than 1.5 million kilowatt hours,
and covers approximately 6 acres of land. The Cedartown energy
storage system is scheduled for commissioning in the second quarter
of calendar year 2015.
“We are at a stage in the industry where we need to develop the
integration requirements for energy storage systems – the control
system requirements, the protection requirements and the modeling
requirements – to make them part of system planning and
operations,” said Mark McGranaghan, vice president of power
delivery and utilization research at EPRI. “This has to happen
before they are needed for widespread deployment. Demonstrations
like this are absolutely key to establishing these models and
requirements.”
The Cedartown solar photovoltaic (PV) facility is part of
Southern Company subsidiary Georgia Power’s Advanced Solar
Initiative, which was designed to tap into Georgia’s competitive
solar marketplace and cultivate cost-effective options for Georgia
Power customers. Washington Gas Energy Systems owns and operates
the array under a 20-year power purchasing agreement. Inman Solar
designed and installed the system. Polk County owns the property on
which the systems are built. The solar array is located at 151 N.
Park Blvd. in Cedartown.
