EquiPower Plans to Retire 1,492-MW Brayton Point Power Station in Massachusetts
LCG, October 15, 2013--EquiPower Resources, a unit of Energy Capital Partners unit, announced last week that it has decided to retire the 1,492-MW Brayton Point Power Station in Massachusetts as of May 2017. The company stated that it has notified ISO New England, the grid operator.
EquiPower stated that the decision is driven by low electricity prices caused in part by low natural gas prices and the significant investment costs required to comply with environmental regulations and operate and maintain the power station. Moreover, lack of success in New England's capacity market reduced the economic outlook for the power station.
"We regret that we were not able to obtain approval from ISO New England to participate in the ISO New England forward capacity market at price levels that would allow Brayton Point to remain viable," stated the CEO and President of Brayton Point Energy LLC.
Brayton Point Power Station includes three coal-fired units and one oil- or gas-fired unit. Commercial operations of the first unit commenced in 1963.
Last March, Dominion announced its agreement to sell Brayton Point Power Station, along with two other power stations, to Energy Capital Partners. Dominion had owned Brayton Point since 2005, after purchasing the facility from PG&E.
The other two power stations in the transaction are Kincaid Power Station, a 1,158-MW power station in Illinois, with two 579-MW coal-fired units; and Elwood Power Station, a 1,424-MW power station near Chicago, with nine natural gas-fired combustion turbines. Dominion had owned a 50 percent interest (712 MW) in and operated the station since Elwood became operational in 1999.
