AB 2464 California Assembly · 2025-2026 Regular Session

Energy: firm zero-carbon resources.

Summary
Existing law requires the State Energy Resources Conservation and Development Commission (Energy Commission) , in consultation with the Public Utilities Commission (PUC) , the Independent System Operator, and the State Air Resources Board, on or before December 31, 2023, to submit to the Legislature an assessment of the firm zero-carbon resources that support a clean, reliable, and resilient electrical grid in the state and will achieve the policy of the state that eligible renewable energy resources and zero-carbon resources supply 100% of all retail sales of electricity to the state's end-use customers and 100% of electricity procured to serve all state agencies by December 31, 2045, as specified. This bill would require the Energy Commission, working with the PUC, to prepare and submit to the Legislature, on or before January 1, 2028, a statewide assessment of the role and necessity of firm zero-carbon resources in meeting the state's clean energy and reliability objectives, potential technologies and strategies for integrating firm zero-carbon resources into the state's energy mix, recommendations on procurement, policy, and planning actions to deploy and support firm zero-carbon resources, and current and projected renewable and firm zero-carbon generation capacity, reliability requirements under varying system conditions, and the cost and emission implications of firm zero-carbon resources.

MODERATE
The amendment adds a new parallel assessment requirement (Section 25240 of the Public Resources Code) that requires the Energy Commission, working with the PUC, to submit a statewide assessment on 'firm zero-carbon resources' by January 1, 2028. This sits alongside the original Section 913.7 requirement for the PUC to assess 'clean, firm resources' by June 30, 2027. The amendment effectively creates two separate assessments with different lead agencies, different terminology, and different deadlines, broadening the bill's scope from a single PUC-led study to a dual-agency framework.
Scope change
The bill now covers two separate assessment requirements under two different codes (Public Utilities Code and Public Resources Code) with different lead agencies, different resource definitions, and different deadlines, rather than a single PUC-led assessment.
SCOPE

New Section 25240 added to the Public Resources Code requiring the Energy Commission (working with the PUC) to prepare and submit a statewide assessment on firm zero-carbon resources by January 1, 2028. This is a separate and additional requirement beyond the original PUC-led assessment.

Bill title expanded from 'an act to add Section 913.7' to 'an act to add and repeal Section 913.7... [and] 25240 of the Public Resources Code,' reflecting the broader scope covering two code sections.

DEFINITION

Introduces the term 'firm zero-carbon resources' as defined in Section 25305.5 of the Public Resources Code, distinct from the 'clean, firm resources' terminology used in the original Section 913.7.

TIMELINE

The new Energy Commission assessment has a later deadline (January 1, 2028) compared to the original PUC assessment (June 30, 2027). The new section also includes a sunset date of January 1, 2032.

REQUIREMENT

The new Section 25240 adds 'safety' to the list of areas for recommendations (procurement, policy, safety, and planning actions) and requires compliance with Section 9795 of the Government Code for legislative report formatting.
