CA SB887

Requires the Public Utilities Commission (PUC) to request the California Independent System Operator (ISO) by January 15, 2023, to identify highest priority transmission facilities needed to increase capacity into local capacity areas for renewable and zero-carbon energy resources expected to be developed by 2035.

Requires the PUC, in consultation with the California Energy Commission, to provide annual transmission-focused guidance to the ISO by March 31, 2024, including 15-year resource projections, load growth forecasts, and renewable energy build-out plans to support the ISO's transmission planning process.

Establishes state policy that transmission facility planning should minimize wildfire risk, increase system-wide reliability and cost efficiency, and eliminate constraints preventing renewable energy generation from reaching load centers and the wider grid.

Requires guidance to include projections for offshore wind generation, electricity imports from other Western states, energy storage resources, and alternatives to transmission expansion for reducing reliance on nonpreferred resources in local capacity areas.

Took effect September 16, 2022, and includes no state reimbursement requirements for local agencies or school districts.
