California Regulators Consider Requiring Energy Storage to Replace Three Gas Plants

By Editors of Power Engineering

The California Public Utilities Commission could soon require Calpine replace three natural gas plants in the state with energy storage.

The regulators will vote on the matter January 11, the Los Angeles Times reported.

Both Calpine and the California Independent System Operator oppose the move, saying the plants are needed to ensure reliability.

Two of the targeted gas plants are in Feather River and Yuba, and total 47 MW each. The third, in Metcalf, totals 605 MW. None of the three have long-term contracts with utilities.

An investigation by the Los Angeles Times concluded California overbuilt the state’s electrical system, primarily with natural gas facilities.
