On August 30, 2021, the California Energy Commission (CEC) held a workshop on its Midterm Reliability Analysis and Incremental Efficiency Improvements to Natural Gas Power Plants. CEC Commissioners Gunda and Douglas were in attendance, as were California Public Utilities Commission (CPUC) Commissioners Rechtschaffen and Houck. CEC staff covered midterm (2022-2026) capacity needs, and potential thermal capacity needs, as well as permitted and potential thermal capacity additions. The workshop also included a panel discussing the deployment and performance of battery energy storage, including a discussion of the risks that could impact California’s planned reliance on large amounts of battery energy storage (over 14,000 MW by 2032 in the CPUC’s recently-released draft Preferred System Portfolio).
The CEC staff’s Midterm Reliability Analysis consisted of a loss of load expectation (LOLE) analysis of a variety of scenarios built around various assumed procurement portfolios, including the CPUC’s draft PSP and a scenario based upon procurement already ordered by the CPUC (1,505 MW NQC from D.19-11-016, and either 9,500 or 11,500 MW NQC from D.21-06-035). The Analysis focused on the May through October time frame, not the entire year. It also assumed that procured resources would show up. Finally, it did not evaluate the impact of extreme weather events.
