Massachusetts Plants to Be Retired

LCG, May 12, 2003--Four power generating units in Massachusetts that are owned by Exelon Corp. will be retired this year, according to the company.

A new, 800-megawatt power plant that was built on the same site as three of the units, in the town of Everett, started operations in April. Mystic Station 4, 5 and 6 will be retired, as will New Boston Station's Unit 1, a 380-megawatt plant in South Boston. The total amount of capacity being retired is put at 756 megawatts.

Massachusetts' government had wanted the units, which run on oil and coal, to be shut down in order to reduce emissions. Exelon also contends that keeping the plants running would be a more costly exercise than makes good business sense. The units would likely have needed upgrades and enhancements to make them competitive.

Before the shutdowns, an additional new 800-megawatt Mystic unit, number 9, is expected to come on line by this month or next month. Exelon has submitted an application to the New England ISO, seeking the grid operator's approval, which is subject to the need for reliability.

Other relatively dirty plants the state would like to be retrofitted in order to continue operating are NRG Energy, Brayton Point, Salem Harbor, Mount Tom Station, and Canal Electric.
