California’s AB 2514 requires the CPUC and municipal utilities in California to open proceedings by March 1, 2012 to determine appropriate targets, if any, for the procurement of viable and cost-effective energy storage systems by load-serving entities. By October 1, 2013, the CPUC must (1) determine whether a procurement target for energy storage is appropriate and, if so, (2) adopt a procurement target for each load-serving entity under its jurisdiction to be achieved by December 31, 2015 and a second target to be achieved by December 31, 2020. Municipal utilities have an additional year to meet these requirements.

In December of last year, the CPUC opened Rulemaking 10-12-007 both to implement AB 2514 and “on [the CPUC’s] own motion to initiate policy for California utilities to consider the procurement of viable and cost-effective energy storage systems.” Order Instituting Rulemaking (“OIR”) at 1, R.10-12-007.

On March 9, 2011, a workshop was held to address the scope of the rulemaking proceeding. The workshop included discussions of current and emerging energy storage technologies, the goals and applications of energy storage, existing barriers to storage implementation, and whether a unified storage policy would work or whether the policy should be written to address specific barriers to entry. The workshop also considered how the CPUC could and should work with other agencies addressing energy storage or related issues, including the California Energy Commission, the California Independent System Operator, and the Federal Energy Regulatory Commission. You can find Seth Hilton’s report about the March 9 workshop here.

The CPUC has scheduled a pre-hearing conference in the rulemaking proceeding for April 21, 2011. The conference will be held before ALJ Amy C. Yip-Kikugawa, beginning at 10 am, in the Commission Courtroom, State Office Building, 505 Van Ness Avenue, San Francisco, California.
