Geothermal powerplants and projects: certification and environmental review.

Abstract

Existing law establishes and vests in the State Energy Resources Conservation and Development Commission (Energy Commission) various responsibilities with respect to developing and implementing the state's energy policies. Existing law authorizes persons proposing specified electrical generation, electrical transmission, hydrogen production, and energy storage projects to apply, on or before June 30, 2029, to the Energy Commission to certify sites and related facilities as environmental leadership development projects, as specified. Existing law makes a site and related facility certified by the Energy Commission subject to streamlining benefits related to CEQA with no further action by the applicant or the Governor. Under existing law, the Energy Commission's certification is in lieu of any permit, certificate, or similar document required by any governmental agency and supersedes any applicable statute, ordinance, or regulation, except as specified. This bill would expand the types of facilities eligible to be certified as environmental leadership development projects by the Energy Commission to include geothermal powerplants and projects that comprise multiple geothermal powerplants on a single site. This bill would incorporate additional changes to Section 25545 of the Public Resources Code proposed by SB 254 to be operative only if this bill and SB 254 are enacted and this bill is enacted last.
