Electric Energy Storage

Overview

In December 2010, the CPUC opened Rulemaking R.10-12-007 to set policy for California utilities and load-serving entities (LSEs) to consider the procurement of viable and cost-effective energy storage systems.

Under terms of state law embodied in AB 2514 (Skinner), by October 1, 2013, the CPUC shall adopt an energy storage procurement target, if determined to be appropriate, to be achieved by each LSE by December 15, 2015, and a 2nd target to be achieved by December 31, 2020.

In addition, the CPUC should consider a variety of possible policies to encourage the cost-effective deployment of energy storage systems, including refinement of existing procurement methods to properly value energy storage systems.
