FERC okays market authority for AltasGas Ripon plant in California

The Federal Energy Regulatory Commission on April 21 approved a Feb. 2 filing by AltaGas Ripon Energy Inc. of a tariff under which it will engage in wholesale sales of electricity, capacity, and ancillary services at market-based rates.

AltaGas Ripon owns and operates a qualifying natural gas-fired cogeneration facility with a capacity of approximately 49.5 MW located in Ripon, San Joaquin County, California. The Ripon Facility is interconnected with Pacific Gas & Electric (PG&E) within the California Independent System Operator balancing authority area.

The company has operated the Ripon Facility as a qualifying cogen and is committed to sell the entire output to PG&E under a power purchase agreement that was entered into under the Public Utility Regulatory Policies Act of 1978 (PURPA). However, beginning in the first quarter of 2015, it will sell the entire output of the Ripon Facility to PG&E under a long-term tolling agreement that will expire on May 31, 2018. Because it will no longer be selling the Ripon Facility’s output to PG&E under a PURPA contract, AltaGas Ripon submitted this application for authorization to make wholesale sales of electric energy, capacity, and ancillary services at market-based rates.

AltaGas Ripon is a wholly-owned subsidiary of AltaGas Power Holdings (U.S.) Inc., which is a wholly-owned subsidiary of AltaGas Services (U.S.) Inc. AltaGas Services is a wholly-owned subsidiary of AltaGas Ltd., a Canadian corporation.
