AB 531: Geothermal powerplants and projects: certification and environmental review.

California · Assembly · 2025–2026 Regular Session · last verified December 13, 2025

What AB 531 does, verified December 13, 2025

This bill would expand the types of facilities eligible to be certified as environmental leadership development projects, allowing geothermal powerplants and projects comprising multiple geothermal powerplants on a single site to qualify. The certification process would streamline CEQA requirements, eliminating the need for further action by the applicant or governor. The certification would also supersede any applicable statute, ordinance, or regulation, except as specified. This bill incorporates additional changes to the Public Resources Code, making them operative only if the bill and another proposed bill are enacted.
