Electricity prices for Chilean residents on the central SIC
power grid will retroactively decrease an average of 0.4% from
August, the government's National Energy Commission said
Wednesday.
Residential rates are indexed to wholesale electricity prices,
or node rates, which are calculated using international fuel
prices, local generation costs, the peso's exchange rate against
the dollar, water reservoir levels and utilities' capital
expenditures, among other factors.
Chile imports nearly 98% of the fossil fuels it consumes.
For an average home consuming 150 kilowatt-hours a month, the
electricity bill will decrease to 15,568 Chilean pesos ($32.39),
from CLP15,627.
The SIC grid provides power to 90% of Chilean homes from the
northern city of Taltal to the southern island of Chiloe.
The main power companies supplying energy to the SIC grid are
Empresa Nacional de Electricidad SA (EOC, ENDESA.SN), AES Corp.
(AES) through its AES Gener SA (AESGENER.SN) unit, and Colbun SA
(COLBUN.SN).
Electricity prices for residents on Chile's northern SING grid,
meanwhile, will decline an average 5.2% from August,
retroactively.
For an average home consuming 150 kilowatt-hours a month, the
power bill will fall to CLP15,864 from CLP16,729.
SING provides power to 10% of the country's residential clients
and most of the largest copper-mining companies.
Chile's Energy Ministry adjusts wholesale electricity rates
every six months, resulting in increases or decreases in the price
charged to regulated customers, including residential clients.
The commission can also readjust rates between these dates if
any of the factors it takes into consideration vary more than 10%
during the six-month period in which the regulated prices are
valid.
