First energy storage mandate in US enacted by California

The California Public Utilities Commission (PUC) has unanimously approved establishing the first energy storage mandate in the U.S. The mandate, which was approved Thursday, requires the state’s investor-owned utilities buy 200 MW of energy storage by 2014 and 1.325 GW by 2020.

 “This decision establishes a target of 1,325 megawatts (MW) of energy storage to be procured by Pacific Gas and Electric Company, Southern California Edison Company and San Diego Gas & Electric Company by 2020, with installations required no later than the end of 2024, and sets a schedule for procurement of energy storage,” Commissioner Carla Peterman wrote in her proposed decision. “The decision directs these utilities to file separate procurement applications containing a proposal for their first energy storage procurement period by March 1, 2014.”

A press released by the CPUC stated that the three main points of the decision are to optimize the grid, including contribution to reliability needs or deferment of T&T upgrade investments; integrate renewable energy; and reduce greenhouse gas emissions to 80 percent below 1990 levels by 2050, per California’s goals.
