The Federal Energy Regulatory Commission on Sept. 4 approved a June 26 application from Hazle Spindle LLC for market-based rate authority related to a 20-MW energy storage project in Pennsylvania.
The proposed market-based rate tariff provides for the sale of ancillary services, specifically, regulation and frequency response service, energy imbalance service, and operating reserve services at market-based rates. Hazle requested waivers commonly granted to similar market-based rate applicants.
Hazle will own and operate a 20-MW energy storage facility that will use flywheel technology to provide ancillary services into the PJM Interconnection system. The facility will be located in Hazle Township, Pa. This proposed facility will maintain an interconnection service agreement with PPL Electric Utilities and be interconnected to PJM’s northeast region via a 69-kV line.
Hazle is an indirect subsidiary of Rockland Power Partners LP (RPP). RPP and its affiliates own or control a total of 721 MW in the PJM market, 701 MW in the PJM East submarket, and 20 MW in the New York Independent System Operator (NYISO) market.
The June 26 filing noted that another RPP affiliate, Stephentown Spindle LLC, uses flywheels to provide 20 MW of Regulation Service to the NYISO market. The Stephentown facility is interconnected with the transmission system of New York State Electric & Gas.
Hazle affiliates also own:
- the Beacon Power Flywheel System 1 (which has been operating with less than 1 MW of capacity) in the ISO-New England Alternative Technology Regulation Pilot Program; and
- the Beacon Power Flywheel System 2 (which has not been operating, but may return to service with less than 1 MW of capacity in the next year) in the ISO-NE Alternative Technology Regulation Pilot Program.
