Exelon to add 195 MW of peaking capacity at Massachusetts power plant

Exelon Generation said Feb. 5 that it will add 195 MW of highly efficient, fast-starting electric generation capacity to help meet future energy needs in New England, which would be through two new generation units at its existing facility in Medway, Mass.

The units will operate primarily during times of peak energy demand. Both units will run mainly on natural gas, but will have the ability to run on ultra-low-sulfur distillate fuel oil as a back-up, ensuring fuel diversity and reliability, Exelon noted. The state-of-the-art units will enhance the reliability of the New England region’s electric system, and provide a fast-starting back-up for intermittent renewable energy sources, such as solar and wind, the company added.

Both units will be equipped with the latest emissions control technology and will meet all applicable federal and state environmental regulations.

Exelon Generation is currently in the permitting phase for the Medway expansion. Construction is expected to begin in 2017 and be completed by mid-year 2018.

“We are excited to develop this new project in the greater Boston area,” said Ron DeGregorio, president, Exelon Power and senior vice president of Exelon Generation. “This project demonstrates the new ‘pay for performance’ capacity construct works and that it will attract development of new resources needed in the region.”

Exelon Generation currently owns and operates approximately 2,200 MW of both combined cycle and peaking generation in the Boston area, including the existing three-unit, oil-fired, 117-MW peaking facility in Medway, where the expansion will be built.

Parent Exelon Corp. (NYSE: EXC) is the nation’s leading competitive energy provider. Headquartered in Chicago, Exelon does business in 48 states, the District of Columbia and Canada. Exelon is one of the largest competitive U.S. power generators, with approximately 35,000 MW of owned capacity comprising one of the nation’s cleanest and lowest-cost power generation fleets.
