AltaGas Pomona seeks market authority for 20-MW storage project in California

AltaGas Pomona Energy Storage Inc. on Sept. 27 asked the Federal Energy Regulatory Commission to accept its market-based rate schedule under which it will sell electric energy, capacity, and ancillary services at market-based rates.

Applicant owns a batter storage facility with a capacity of approximately 20 MW located in Pomona, California. This Pomona Energy Storage Facility is interconnected with Southern California Edison (SCE). It is expected to be in-service in December of this year.

AltaGas Pomona will purchase energy on a wholesale basis in order to charge the Pomona Energy Storage Facility. The stored energy will then be sold into the California Independent System Operator (CAISO) market on a merchant basis, with the amount being sold being limited by the applicant’s energy storage capacity.

Applicant will connect with the grid by utilizing the limited interconnection facilities currently owned by an affiliate (AltaGas Pomona Energy Inc.) that operates a cogeneration facility that is adjacent to the Pomona Energy Storage Facility.

Applicant is a direct, wholly-owned subsidiary of AltaGas Power Holdings (U.S.) Inc., which is part of AltaGas Ltd., a Canadian corporation that is publicly traded on the Toronto Stock Exchange with the symbol “ALA.”

AltaGas Pomona Energy Inc. owns and operates a qualifying natural gas-fired cogeneration facility with a capacity of about 44.5 MW located in Pomona, California. This San Gabriel Facility is interconnected with SCE. 

A project contact is: John O’Brien, President, AltaGas Services (U.S.) Inc., Park Seventeen, Suite 1040, 1717 McKinney Avenue, Dallas, TX 75202, telephone: (403) 691-7575, john.obrien@altagas.ca.
