CALIFORNIA LEGISLATURE— 2025–2026 REGULAR SESSION

Assembly Bill

No. 1484

Introduced by Assembly Member Bennett

February 21, 2025

An act to amend Section 345 of the Public Utilities Code, relating to energy.

LEGISLATIVE COUNSEL'S DIGEST

AB 1484, as introduced, Bennett. Energy reliability.

Existing law establishes the Independent System Operator (ISO) as a nonprofit, public benefit corporation to ensure efficient use and reliable operation of the transmission grid and to manage the transmission grid and related energy markets, as specified. Existing law requires the Public Utilities Commission (PUC), in consultation with the ISO, to establish resource adequacy requirements for all load-serving entities, defined as including electrical corporations, electric service providers, and community choice aggregators. Existing law, in establishing resource adequacy requirements, requires the PUC to ensure the reliability of electrical service in California, as provided. Existing law requires the ISO to ensure the efficient use and reliable operation of the transmission grid, consistent with certain criteria, and authorizes the ISO to amend its tariff to be consistent with that requirement, as deemed necessary and subject to approval by the Federal Energy Regulatory Commission.

This bill would make a nonsubstantive change to the provision requiring the ISO to ensure the efficient use and reliable operation of the transmission grid.
