ZGlobal Retained to Evaluate the Impact of Assembly Bill 2787

California is experiencing unprecedented changes in the generation, delivery, and consumption of electricity. Along with these changes come challenges for operating the state’s electrical grid and resources in the most efficient manner, particularly in terms of the time-sensitive need to match generation to the demand for electricity.

As part of the long-term procurement planning process at the Public Utilities Commission, the ISO has identified a need for fast-ramping and flexible resources to balance the electrical grid and store low-cost energy from renewable energy resources. The bill states, “On or before December 31, 2019, the Independent System Operator shall complete a procurement process for procuring one or more long duration bulk storage projects that have an aggregate capacity of at least 1,000 megawatts, but not more than 2,000 megawatts, unless the Independent System Operator determines that procurement in excess of the 2,000-megawatt limit maximizes the efficiency of sizing the long duration bulk energy storage projects procured.”
