Discussion Existing Energy Storage Projects Based on the definitions accepted under the use cases and Section 2835(a), we find that all of the storage projects identified in the Proposed Plan should be counted towards the IOUs’ procurement targets provided that they meet the following requirements: The project demonstrates its ability to meet one or more of the following purposes: grid optimization, integration of renewable energy, or reduction of greenhouse gas emissions. The project is under contract or was installed after January 1, 2010. The project is operational by no later than the end of 2024. Other IOU storage projects that were not identified in the Proposed Plan, such as PG&E’s Vaca-Dixon Battery Project and Yerba Buena Battery Project, should also count towards the IOU’s procurement targets once they have reached commercial operation and meet the three requirements above. Similarly, energy storage capacity that could be obtained from plug-in vehicles and programs/systems that utilize electric vehicles for grid services (Vehicle to Grid) could count towards procurement targets. We further emphasize that since the objective of AB 2514 is to increase the use of energy storage systems, and not to identify existing energy storage systems, we do not believe it would be reasonable to count projects that were in existence prior to January 1, 2010 towards the procurement targets. This limitation is consistent with Section 2835(c), which defines a new energy storage system as a “system that is installed and first becomes operational after January 1, 2010.”
