Joint Agency Reliability Planning Assessment: Covering the Requirements of SB 846 (Combined First and Second Quarterly Report for 2025) and SB 1020 (Annual Report)

The Joint Agency Reliability Planning Assessment addresses requirements for electricity reliability reporting in Senate Bill 846 (Dodd, Chapter 239, Statutes of 2022) and Senate Bill 1020 (Laird, Chapter 361, Statutes of 2022). The report provides the first quarterly review of 2025, including the demand forecast, supply forecast, and potential high, medium, and low risks to reliability in the California Independent System Operator territory from 2025 to 2035, as required by Senate Bill 846. As required by Senate Bill 1020, this report also provides a joint reliability progress report that reviews system and local reliability, with a particular focus on summer reliability, identifies challenges and gaps to achieving system and local reliability, and identifies the amount and cause of any delays to achieving compliance with all energy and capacity procurement requirements set by the California Public Utilities Commission.
