Pacific Gas and Electric Company (PG&E) expanded its commitment to clean energy by presenting its first 75 MW of energy storage contracts to the California Public Utilities Commission (CPUC) for review and approval.

The seven projects selected include four Lithium Ion Battery projects, two Zinc/Air Battery storage facilities and one Flywheel project, a first for PG&E. The first projects are due to come online in May of 2017.

California’s energy storage decision requires investor-owned utilities to procure 1,325 MW of storage by 2020. PG&E’s share is 580 MW.

Storage is expected to play an increasingly important role for California utilities as they work to achieve the states ambitious clean energy goals. By the end of 2015, PG&E forecasts that about 30 percent of its retail electric deliveries will come from renewable sources. Energy storage will help integrate many of those resources, such as wind and solar, which are intermittent or provide peak output during times of low demand.

 

Energy storage to be added to PG&E solar PV facilities

PG&E issued a list of five distribution substations where it would like to consider energy storage projects on distribution circuits to defer distribution investments. PG&E also identified three sites where it owns and operates solar photovoltaic (PV) facilities where energy storage could be added.

“PG&E supports the state’s efforts to enable energy storage to play its appropriate role in the California electric grid to support the integration of utility scale and customer connected renewables, and is excited to take this first step in implementing these goals,” said Fong Wan, PG&E senior vice president for Energy Policy and Procurement,
