PG&E Plans Largest-Ever Storage Project at 300 MW Natural Gas Plant
Pacific Gas and Electric Co. (PG&E) has filed plans with the California Public Utilities Commission (CPUC) to launch a 570 MW, four-project effort with lithium-ion batteries, the largest tied to an existing natural gas-fired generation plant at Moss Landing.
A 300 MW battery is to be installed at a plant owned and operated by Texas-based Vistra Energy Corp., which would own the largest-ever battery.
“This installation would be capable of running for four hours while putting out the same amount of power as a small natural gas-fired plant,” said a PG&E spokesperson.
A second project, a 10 MW lithium-ion battery, is planned at a customer’s facilities behind the meter at Micronoc Inc., which would be the first to come online in October 2019.
A third battery project, Hummingbird Energy Storage LLC in Morgan Hill, would be a 75 MW battery installation, while the fourth is a 182.5 MW Tesla Inc. project. The Hummingbird and Tesla projects are slated to begin operating in December 2020.
All of the projects are in what PG&E designates as the Moss Landing sub-area in Monterey County. All but the Micronoc project are transmission-connected.
A subsidiary of Vistra, Dynegy Marketing and Trade LLC, would own the third-party storage project. Dynegy, now merged with Vista, manages a portfolio of 41 GW of installed capacity across 12 states.
