Battery Backup for PSPS & Wildfire Outages in Los Angeles
PSPS (Public Safety Power Shutoff) events can cut power for days across LA and Orange County wildfire-risk communities. A solar + battery system may provide quiet backup for selected loads and can recharge from panels during daylight when system configuration and weather allow. Tesla Certified Premium Installer.

PSPS in Los Angeles and Orange County: what to expect.
PSPS (Public Safety Power Shutoff) events are pre-planned utility outages designed to reduce wildfire ignition risk during extreme fire weather — high winds, very low humidity, and critically dry vegetation. SCE has implemented PSPS across much of its LA County and Orange County service area. LADWP has also conducted planned outages in high fire-risk communities it serves.
- →Duration varies widely. PSPS events can last from a few hours to 72 hours or more, depending on fire weather forecasts and when utilities can inspect lines before restoration. Multi-day events are common in foothill and canyon communities.
- →High-risk communities. Foothill and canyon communities across LA and OC are most frequently affected: Malibu, Topanga, Pacific Palisades, Altadena, La Cañada, Anaheim Hills, Yorba Linda, Trabuco Canyon, and others. SGIP’s High Fire Threat District mapping identifies Tier 2 and Tier 3 areas.
- →Fuel and generator limitations. During regional PSPS events, gasoline supplies can run short and generator noise and exhaust make prolonged indoor operation impractical. Battery + solar can reduce reliance on those constraints, depending on system design and available solar production.
Multi-day backup: the solar + Powerwall strategy.
- →Battery can store energy before PSPS hits. When SCE announces a PSPS event (typically 24–48 hours ahead), the Tesla app can maximize battery charge before the shutoff begins. The battery enters backup mode the moment grid power drops.
- →Solar recharges during the day. With the right inverter configuration, solar panels continue generating during a grid outage (island mode) and recharge the battery. Each sunny day during a PSPS event may extend backup duration, depending on load management, battery capacity and solar production.
- →Load management extends backup. During a multi-day PSPS event, managing which loads run simultaneously — not running large loads at the same time, for example, can help extend runtime. The Tesla app can show battery level and estimated time remaining.
- →No noise, no exhaust, no fuel. Battery backup operates silently and does not produce exhaust, making it usable indoors and respectful of neighbors in densely-built LA communities.
Specific backup duration depends on system design, battery capacity, weather and load during PSPS events — runtime depends on battery capacity, load, solar production, and weather. We model estimated performance during your estimate.
Special SGIP incentives for high fire-risk homes.
California’s Self-Generation Incentive Program (SGIP) has included resilience and equity pathways for qualifying battery storage and paired solar plus storage projects, but rules, funding, budget categories, and application requirements change. Eligibility should be confirmed for the specific address, utility, customer, equipment, and application window.
- →Who may qualify. Wildfire exposure, PSPS history, income rules, utility territory, battery size, and program category may affect eligibility. Do not rely on fire-risk designation alone.
- →No guaranteed rebate. SGIP rebates depend on reservation window, available program funding, battery size, documentation, demand-response requirements, and current program rules. Rebates are subject to program administrator approval.
- →Permitted work required. SGIP projects must follow program requirements and pass inspection. We coordinate permitting as part of every battery installation.

PSPS and wildfire backup questions.
What is a PSPS outage and why does it happen in Los Angeles?
PSPS stands for Public Safety Power Shutoff. Electric utilities (primarily SCE in the LA/OC area) proactively cut power to reduce wildfire ignition risk when dangerous fire weather conditions — high winds, low humidity, dry vegetation — combine with stressed electrical equipment. PSPS events can last from hours to several days and affect tens of thousands of customers across LA and OC counties.
Does LADWP do PSPS shutoffs like SCE?
LADWP has conducted its own planned outages in high fire-risk areas, though the program and criteria differ from SCE’s PSPS program. Customers in hillside, canyon, and brush-adjacent communities served by LADWP — including parts of Pacific Palisades, Brentwood hills, Studio City hills, and others — should plan for potential planned or unplanned outages during fire weather events regardless of utility.
How does a home battery help during a PSPS outage?
A home battery system stores electricity during normal grid operation and supplies it during a grid outage — including a PSPS event. Paired with solar, the system may continue charging the battery from panels during the day, depending on inverter configuration, weather and system design. Battery backup can support selected circuits or broader loads based on approved electrical configuration.
Are there SGIP incentives for homes in wildfire-risk areas?
SGIP has included resilience and equity pathways for qualifying battery storage and paired solar plus storage projects, but eligibility and funding must be confirmed at the time of application. Wildfire risk, PSPS history, income rules, utility territory, battery size, reservation window, demand-response requirements, and program administrator rules can all affect eligibility. We review current SGIP options during your estimate.
Can solar extend PSPS backup for multiple days?
Yes, in the right system configuration. When solar panels are generating and the inverter is properly set up for backup (island) mode, they can continue charging the battery during a daytime outage. Over a multi-day PSPS event, solar recharging can extend backup during daylight hours, depending on load management and solar production. Specific backup duration depends on system design, battery capacity, weather and load — runtime depends on weather, cloud cover, and load.
Should I get a generator or a battery + solar for wildfire backup?
Battery + solar may offer quiet backup and daytime recharging when the system is configured for backup mode and solar production is available. Generators require fuel (which may not be readily available during a regional emergency), are noisy, produce exhaust, and require manual startup. The right choice depends on your backup load requirements, budget, and how long you need to sustain power. We discuss both options during your estimate.
Which LA and OC areas are most affected by PSPS?
SCE publishes fire threat district maps; PSPS events most frequently affect communities in Tier 2 and Tier 3 High Fire Threat Districts — including foothill and canyon communities across LA County and parts of Orange County. Utility territory and fire threat district status should be confirmed by address because SCE, LADWP and municipal utilities follow different rules and programs. We review available mapping and utility information during the estimate.
