Moss Landing burned. Twelve days later OC paused BESS.
On January 28, 2025, the Orange County Board of Supervisors enacted an emergency moratorium on new BESS facilities in unincorporated Orange County. The trigger: a January 22 letter from Vice Chair Katrina Foley, written six days after the Vistra-operated Moss Landing fire. Cited grounds: health, safety, welfare, CAL FIRE hazard mapping, and absent county siting guidelines.
Cited unincorporated OC BESS entitlement-risk read: 20/100 through the moratorium window.

Moss Landing BESS fire ignites in Monterey County
The Vistra-operated Moss Landing Energy Storage Facility — at the time the largest Li-ion installation in the U.S. — ignites, burns for days, forces evacuations, and closes Highway 1. The incident becomes the reference event for coastal-California BESS moratorium actions over the following weeks.

Vice Chair Katrina Foley requests emergency moratorium
Orange County Board of Supervisors Vice Chair Katrina Foley sends a letter to the Board of Supervisors requesting passage of an emergency BESS moratorium at the January 28, 2025 meeting. The letter frames the request around the recent Moss Landing fire and the absence of county-level BESS-specific siting guidelines.

Orange County Board enacts emergency BESS moratorium
The Orange County Board of Supervisors enacts an emergency moratorium on approval of any new Battery Energy Storage System facility in unincorporated Orange County. Cited grounds include recent utility-scale lithium-ion battery fires, county drought status, CAL FIRE-designated high and very-high fire hazard severity zones, and the absence of county-level BESS siting guidelines. Duration: six months.
January 28, 2025 — April 2025
OC Public Works + Orange County Fire Authority develop recommendations
Per the emergency ordinance, Orange County Public Works staff are directed to coordinate with the Orange County Fire Authority (OCFA) to issue recommendations for alleviating hazardous BESS conditions before the moratorium expires. Those recommendations become the template for the successor permanent framework.
2025 — Beyond
Orange County joins the coastal-California BESS pause pattern
The OC moratorium sits alongside Monterey County's post-Moss-Landing moratorium drafting action and Morro Bay's unanimous two-year ban as part of a coastal-California BESS pause pattern. Any California BESS portfolio now needs county-by-county tracking for moratorium status and successor siting rules.
The Decision Graph
A letter. A Board vote. A Fire Authority brief.
The actors that moved OC from no-specific-BESS-rules to emergency-moratorium in twelve days.
Katrina Foley
Vice Chair, OC Board of Supervisors
Orange County, CA
Documented Record
Initiated the emergency ordinance request in a January 22, 2025 letter to the Board of Supervisors requesting passage at the January 28 meeting, citing the Moss Landing fire and absent county BESS siting rules.
Foley is the visible political author of the moratorium. Any future BESS applicant in unincorporated OC will route through her framing of the 'health, safety and welfare' record.
OC Board of Supervisors
Legislative body
Orange County, CA
Documented Record
Enacted the emergency moratorium on new BESS facilities in unincorporated Orange County at the January 28, 2025 meeting, per Energy-Storage.News coverage.
Board-level consensus on an emergency action tells applicants the successor framework will likely impose stricter siting and safety standards rather than simply reauthorizing the status quo.
OC Public Works
County department — successor framework lead
Orange County, CA
Documented Record
Charged by the emergency moratorium ordinance with coordinating with the Orange County Fire Authority to issue recommendations for alleviating hazardous BESS conditions before the moratorium expires.
Public Works holds the pen on the successor siting framework. Engagement with this department during the drafting window is the single highest-leverage activity for BESS operators.
Orange County Fire Authority (OCFA)
Fire safety authority
Orange County, CA
Documented Record
Co-tasked with OC Public Works on developing the post-moratorium BESS siting and safety recommendations, per the moratorium ordinance.
OCFA will drive technical standards — NFPA 855 compliance, thermal runaway detection, water supply, and setbacks — and will likely tighten them post-Moss-Landing.
Moss Landing BESS fire (precedent event)
Trigger event
Monterey County, CA
Documented Record
The January 16, 2025 Vistra-operated Moss Landing BESS fire — at the time the largest Li-ion installation in the U.S. — is referenced in the OC moratorium as the catalytic precedent event for the emergency action.
Moss Landing is the benchmark cautionary event for coastal-California BESS policy action. Any siting memo from 2025 onward should treat it as a fixed reference point.
What Makes This Moratorium Sticky
Every factor here points toward stricter successor rules.
Six structural reasons the post-moratorium framework will not simply restore the January 27 status quo.
Moss Landing as Benchmark Event
Once a precedent event has caused evacuations and a highway closure, local officials cannot credibly pretend it didn't happen. The successor framework will be graded against it.
CAL FIRE Hazard Zones
Large swaths of unincorporated OC sit inside CAL FIRE-designated high and very-high Fire Hazard Severity Zones. That mapping alone narrows viable BESS siting materially.
OCFA Leading Technical Standards
When a Fire Authority leads BESS technical standards, expect NFPA 855 upgrades, on-site water supply requirements, thermal-runaway detection mandates, and tighter setbacks.
Political Author Still in Office
Vice Chair Katrina Foley authored the moratorium letter and remains a seated supervisor. Policy continuity between emergency ordinance and permanent framework is high.
Emergency Ordinance Precedent
Enacting on a health-safety-welfare emergency basis makes subsequent legal challenges harder. Courts give wide deference to emergency public-safety determinations.
Coastal California Pattern Lock-In
OC joins Monterey and Morro Bay in a post-Moss-Landing pattern. Once three coastal counties move together, the political cost of returning to pre-fire rules becomes prohibitive.

Jurisdiction Analysis
BESS — Unincorporated Orange County
Orange County, CA — emergency moratorium posture
Material Constraints
- January 28, 2025 emergency moratorium on new BESS in unincorporated Orange County
- Cited grounds: health, safety and welfare — CAL FIRE high/very-high hazard zones
- Duration: six months; expected to remain in force through April 2025 at minimum
- County has no BESS-specific siting guidelines on the record
- Public Works + Orange County Fire Authority charged with new siting recommendations
Recommendation
DO NOT FILE new BESS applications in unincorporated Orange County during the moratorium window. Re-underwrite after the Public Works + OCFA recommendations establish the successor siting framework. Incorporated cities inside Orange County are governed by their own zoning, but expect parallel pressure post-Moss-Landing.
This Is Entitlement Research
Track BESS moratoria county-by-county, day-by-day.
For submitted sites, RealClear checks emergency ordinances, CAL FIRE hazard zones, and post-Moss-Landing successor frameworks from source-backed public records — so your energy storage portfolio never files into a closed window.
