California’s opt-in certification program for large clean energy projects is commonly searched as “SB 52,” but the California SB 52 opt-in certification requirements people are looking for actually come from Assembly Bill 205, signed in 2022. SB 52, passed in 2021, is a different law that deals with local emergency declarations for planned power shutoffs.1California Legislative Information. California SB-52 State of Emergency Local Emergency Planned Power Outage AB 205 added Chapter 6.2 to Division 15 of the Public Resources Code and gave the California Energy Commission authority to issue a single consolidated certification for qualifying renewable generation, storage, and clean energy manufacturing facilities. The rest of this article walks through what that program actually requires.
Which Projects Qualify
Public Resources Code Section 25545 sets four eligibility categories:2California Legislative Information. California Code PRC 25545 – Certification of Nonfossil-Fueled Powerplants, Energy Storage Facilities, and Related Facilities
- Solar photovoltaic or terrestrial wind facilities with generating capacity of 50 megawatts or more.
- Battery or other energy storage systems capable of storing 200 megawatt-hours or more.
- Thermal power plants of 50 megawatts or more that do not burn fossil or nuclear fuels.
- Facilities that manufacture components for renewable energy or storage systems, when the CEC determines the project meets the applicable criteria.
A 200-megawatt-hour storage system rated at 50 megawatts can discharge at full power for about four hours, which is the grid-scale battery profile the program targets. Projects below the thresholds go through traditional local permitting instead.
What the Application Must Contain
The CEC’s contents rules live at 20 CCR Section 1877. A submission must include everything specified in the regulation’s Appendix B, plus a detailed explanation of how the facility fits the size and type definitions in Section 25545.3New York Codes, Rules and Regulations. 20 California Code of Regulations 1877 – Contents of Opt-in Application Any Appendix B category the developer thinks does not apply still has to be addressed with a written reason.
The application also carries certifications under Public Resources Code Sections 25545.3.3 and 25545.3.5, covering project labor agreements and skilled workforce requirements. The CEC verifies these as part of the certification process.4California Energy Commission. Opt-In Certification Program
Siting disclosures are mandatory. The developer must identify whether the project sits on a prohibited site under Public Resources Code Section 25527, on land designated by the California Coastal Commission, or on land under the San Francisco Bay Conservation and Development Commission’s jurisdiction.3New York Codes, Rules and Regulations. 20 California Code of Regulations 1877 – Contents of Opt-in Application If the project needs incidental take authorization under Fish and Game Code Section 2081(b), or a lake or streambed alteration permit under Section 1602, the underlying biological data must be filed with the application.
Two more items round out the package. The application must list every local, state, or federal permit the developer has filed or plans to file, together with a description of any discussions already held with those agencies. It must also include preliminary information demonstrating a net positive economic benefit to local government, which the CEC then shares with the affected jurisdiction.
Proving Net Positive Local Economic Benefit
The CEC cannot certify a project unless it finds the facility will produce a net positive economic benefit to the local government that would otherwise have had permitting authority over the site.5California Legislative Information. California Code Public Resources Code 25545.9 – Certification of Nonfossil-Fueled Powerplants, Energy Storage Facilities, and Related Facilities The statute names six qualifying categories of benefit: employment growth, housing development, infrastructure and environmental improvements, assistance to public schools, assistance to public safety agencies, and property and sales tax revenues.
The law creates a rebuttable presumption that the project delivers that benefit, which puts the burden on opponents who want to argue otherwise. A developer’s preliminary showing in the application will stand unless a local government or another party produces evidence strong enough to overcome the presumption. This is where local governments have their clearest leverage in the process, and where community opposition tends to concentrate.
The 270-Day Review Timeline
Once the CEC deems the application complete, a 270-day clock begins for the commission to finish environmental review and vote on certification at a public business meeting.4California Energy Commission. Opt-In Certification Program The CEC publishes a day-by-day schedule:6California Energy Commission. Opt-In Certification Program Overview – Pre-Filing Meeting
- Day 0: Application deemed complete.
- Day 3: Notice of Preparation of an Environmental Impact Report filed and circulated.
- Day 5: Tribal consultation invitations sent.
- Day 30: Public scoping meeting held near the project site.
- Day 150: Draft EIR circulated for public comment.
- Day 180 to 210: Public meeting on the draft EIR near the proposed site.
- Day 210: Public comment period closes, 60 days after the draft EIR.
- Day 240: Final EIR and executive director’s recommendation filed.
- Day 270: Commissioners vote to approve or deny at a public business meeting.
- Day 360: Partner agencies with retained permit authority issue their final decisions.
The 270-day window can slip when the draft EIR turns up new significant environmental effects that require recirculation for further comment. Complex projects involving sensitive habitat or water resources often trigger that supplemental analysis, so the statutory clock should be treated as a target rather than a guarantee.
CEQA Review and Tribal Consultation
The CEC acts as the lead agency under the California Environmental Quality Act for every project in the opt-in program and must prepare a full Environmental Impact Report within the 270-day window. For each significant effect the EIR identifies, the commission must find either that the project has been redesigned to avoid or substantially lessen the impact, or that mitigation and alternatives are infeasible. Where a significant unavoidable impact remains, the CEC must adopt a statement of overriding considerations explaining why the project’s benefits justify approval anyway.
Tribal consultation runs on a tight clock. Within five days of an application being deemed complete, the CEC must send consultation letters to California Native American tribes that are culturally and traditionally associated with the project area. The commission has to solicit tribal ecological knowledge, incorporate it into the EIR where feasible, and take all feasible measures to avoid or minimize harm to tribal cultural resources. The CEC has no authority to waive that requirement, and projects sited on or near culturally significant land have drawn serious opposition at this stage.
How Certification Replaces Other Permits
A granted certification is issued “in lieu of any permit, certificate, or similar document required by any state, local, or regional agency” and supersedes applicable ordinances and regulations.7California Legislative Information. Public Resources Code Chapter 6.2 – Certification of Nonfossil-Fueled Powerplants, Energy Storage Facilities, and Related Facilities The language is sweeping, but several agencies keep independent permitting authority and must act on their own permits within 90 days after the EIR is certified:
- California Coastal Commission
- San Francisco Bay Conservation and Development Commission
- State Water Resources Control Board and the regional water quality control boards
- Local air quality management districts
- Department of Toxic Substances Control
The 90-day deadline only applies if the developer has already filed a complete application with each of those agencies before the EIR is certified. Miss that sequencing and the Day 360 partner-agency deadline becomes very hard to hit. Engage these agencies during pre-application discussions rather than treating their permits as follow-on paperwork.
Court Challenges to a Certification
Any lawsuit to overturn a CEC certification or its associated EIR must be resolved, to the extent feasible, within 270 days of filing the certified administrative record with the court.8California Legislative Information. California Code Public Resources Code 25545.13 – Certification of Nonfossil-Fueled Powerplants, Energy Storage Facilities, and Related Facilities Starting January 1, 2026, the CEC must prepare the administrative record concurrently with its project review and certify the record within five days of the certification decision. The Judicial Council adopted rules of court to implement this expedited schedule, which applies through any appeals to the Court of Appeal or Supreme Court.
The “to the extent feasible” qualifier means courts are not strictly bound by the 270-day target, but the Legislature’s signal is clear: CEQA challenges to these projects are meant to move quickly. For opponents, that compressed schedule means putting expert testimony and community input on the record during the CEC proceeding itself. For developers, it means the certification has more durability than a typical local land-use approval.
Grid Interconnection Is a Separate Track
State certification does not connect a project to the grid. Interconnection is governed by the Federal Energy Regulatory Commission, and as of the end of 2022 more than 10,000 active interconnection requests representing over 2,000 gigawatts of potential capacity were sitting in queues nationwide.9Federal Energy Regulatory Commission. Explainer on the Interconnection Final Rule FERC’s Order No. 2023 moves transmission providers from a first-come, first-served serial process to a cluster study process that evaluates projects in batches, though compliance filings from regional transmission organizations and independent system operators are still being reviewed. Interconnection often takes longer than the CEC’s 270-day review, so treat it as a parallel workstream from the start, not a sequential one.
