The 2011 IEPR Committee Workshop on Energy Storage for Renewable Integration was held Thursday, April 28th at the California Energy Commission (CEC) offices in Sacramento. The Workshop was presented in a three panel format, with each panel addressing specific topics, including (1) the need for energy storage in light of California’s renewable portfolio standard, greenhouse gas goals, smart grid and demand response, (2) the costs, benefits and revenues from energy storage applications, and (3) utility perspectives on energy storage. The full agenda, which describes the topics and the questions addressed at the Workshop, can be found here.
The CEC is not planning any further workshops on energy storage, but it will be making recommendations about the topic in its 2011 Integrated Energy Policy Report (IEPR). We understand that the CEC is seeking input on energy storage from all arenas, including developers and owners of gas-fired peaker plants. Among other things, the CEC wants to understand the economic and environmental benefits and impacts of peakers (i.e., facilities that have the ability to ramp up in ten minutes, generate for a full hour, then be taken off line) compared to the cost and benefits of various energy storage technologies. The CEC will use the information it gathers to determine if it makes sense economically to recommend a lower or a higher target for energy storage in its 2011 IEPR.
The CEC’s report will be taken into account by the California Public Utility Commission (CPUC), which is conducting a separate proceeding under AB 2514 to determine appropriate energy storage targets for California’s investor-owned utilities. You can find our previous descriptions of the AB 2514 process here , here and here. A report on last year’s CPUC staff whitepaper describing energy storage technologies and their potential use in the California market can be found here.
Parties who want to weigh in on energy storage in California must submit their comments to the CEC by 5 p.m. on May 16, 2011. The comments must include the docket number “11-IEP-1N” and indicate “Energy Storage for Renewable Integration” in the subject line or first paragraph of the comments. All filings in the IEPR proceeding are now accomplished electronically and can be submitted in either Microsoft Word format or as a PDF by e-mail to firstname.lastname@example.org.
