SB 1158 California Senate · 2025-2026 Regular Session

Energy: reliability planning assessment.

Summary
Existing law requires the State Energy Resources Conservation and Development Commission (Energy Commission) and the Public Utilities Commission (PUC) , on or before December 15, 2022, and quarterly thereafter, to submit to the Legislature a joint Reliability Planning Assessment that, among other things, includes prospective information on existing and expected resources, including updates on the interconnection status for renewable projects and any delays in interconnection, and expected retirements for both system and local resources. Existing law requires the Energy Commission to report in the energy almanac on California energy resources that serve load in California. This bill would require that the assessment also include the status of utility transmission upgrades and electrical grid infrastructure capacity and PUC approvals of applications for certificates of public convenience and necessity and permits to construct utility and independent projects, as specified.

What changed between versions

05/14/26 - Amended Senate SB1158 · 4 edits
MODERATE
The enrolled version of SB 1158 narrowed the scope of the Reliability Planning Assessment compared to the Amended Senate version. Several specific reporting requirements were removed: tracking of substations and expanded transmission corridors, project permit queues from the Energy Commission and ISO, expected completion dates for resources, and a requirement to report on fossil fuel use by Department of Water Resources facilities. These changes likely reflect Assembly amendments that trimmed the bill before final passage.
Scope change
The bill's scope was narrowed: it no longer requires reporting on specific grid infrastructure components (substations, expanded corridors), project permit queues from the Energy Commission and ISO, expected completion dates for resources, or fossil fuel use at Department of Water Resources facilities.
SCOPE

Removed the requirement to report on 'substations and expanded transmission in existing corridors' as part of the grid infrastructure capacity reporting in subsection (5).

Removed subsection (11) in its entirety, which required the assessment to report on fossil fuel use by facilities constructed by, purchased by, or under contract with the Department of Water Resources under Section 80710 of the Water Code.

REQUIREMENT

Removed the requirement to report on 'the status of applications for permits for projects from the commission and the queue of projects from the Independent System Operator, filtered by geographic region and energy resource type.'

Changed 'expected completion dates and retirements for both system and local resources' to just 'expected retirements for both system and local resources,' removing the completion date tracking requirement.
