FERC okays market authority for Exelon’s West Medway II expansion project

The Federal Energy Regulatory Commission on Oct. 27 approved a Sept. 30 application from Exelon West Medway II LLC for market-based rate authority with an accompanying tariff, with that tariff providing for the sale of energy, capacity, and ancillary services at market-based rates.

Applicant is developing and will own and operate an approximately 195 MW (summer rating) facility located in Medway, Massachusetts. The facility will be interconnected to the transmission system owned by NSTAR Electric Co. and operated by ISO New England. It is anticipated that sale of test power from the facility could begin as early as December 2017 and commercial operation is expected in April 2018.

Applicant is part of Exelon Generation Co. LLC, which is a wholly owned subsidiary of Exelon Corp. (NYSE: EXC).

Notable is that FERC on Aug. 15 had accepted a June 27 filing by ISO New England and NSTAR Electric of an executed non-conforming Standard Large Generator Interconnection Agreement with Exelon West Medway II LLCThe deal governs the interconnection of this new capacity at NSTAR’s 115-kV Medway Station. This new facility will be comprised of two new simple cycle combustion turbine generators (CTG), designated CTG1 and CTG2, each rated at 103.467 MW, and located in the Town of Medway, Mass.

This new facility is located at a site adjacent to an existing power plant, which is known as Unit J-3 and is interconnected pursuant to a separate qgreement between NSTAR and West Medway, dated as of 1997. While this new facility is separate from and does not include West Medway’s existing facility, it will be interconnecting to NSTAR’s 115 kV-Medway Station through shared facilities.
