In September 2010, the Legislature passed Assembly Bill (AB) 2514 (Skinner), which required the CPUC to open a proceeding to review and establish, if appropriate, opportunities for the development and deployment of Energy Storage systems throughout California's electricity grid. Energy Storage systems are commercially available technologies that are capable of absorbing and storing energy that can be dispatched for use at a later time.
Beginning in 2015, the CPUC will consider policy and implementation refinements to the Energy Storage Procurement Framework and Design Program, as well as the California Energy Storage Roadmap.
Guided by the CPUC’s Procurement Framework and Design Program, the utilities will submit Energy Storage procurement plans to the CPUC for approval, every two years.
The CPUC set guidelines and Energy Storage targets for the electric utilities of 1325 megawatts (MW) to be procured by 2020, with the first procurement period beginning in 2014.
