Electrical work in Orange County

SCE, Anaheim and the SDG&E south end

Most of the 22 Orange County cities covered on this site get electricity delivery from Southern California Edison. Anaheim is the big exception: Anaheim Public Utilities (APU) serves the whole city. In the south end, San Clemente is on SDG&E, and Aliso Viejo, Laguna Niguel and Mission Viejo are split between SCE and SDG&E by address (in Aliso Viejo, SDG&E is east of Alicia Parkway and SCE west of it). Check the electric bill to see which utility serves an address, because that utility handles the meter and service work.

That matters on the day of a panel upgrade. In Anaheim the city building inspector approves the panel and wiring first. Then APU’s meter shop inspects, and a crew energizes the panel within 3 to 5 business days after both inspections pass. An APU inspector also approves the panel location before work starts. In the SCE and SDG&E cities, the sequence runs through SCE’s service planning and its own inspection and meter steps, and the utility publishes targets only for its own part. The city’s time comes on top of that. See utility coordination for service upgrades.

A smaller layer is Orange County Power Authority (OCPA), the community choice program. Buena Park, Fullerton and Irvine buy default power through OCPA, and Fountain Valley joins in April 2027. OCPA changes the generation price, not the wires, the meter or the permit.

Coast, flatland and foothill

The county splits cleanly by geography, and the split shows up in climate and fire risk.

Coast. Huntington Beach, Newport Beach, San Clemente, Laguna Niguel and Aliso Viejo sit near the ocean. They run little air conditioning compared with inland cities, and no wind shutoff has been reported for them. Newport Beach’s fire concern is its canyons: the State Fire Marshal updated recommended maps on March 24, 2025, and a 2012 city notice designated Buck Gully and parts of Newport Ridge and Newport Coast as Very High.

Flatland. Santa Ana, Garden Grove, Westminster and Fountain Valley are fully built out. Their outages are equipment and heat related. On June 4, 2025, metallic balloons on utility equipment cut power to about 4,631 SCE customers near Westminster Boulevard and Goldenwest Street.

Foothills. Orange County’s wind shutoffs from 2019 to 2022 hit canyon and foothill circuits. The Silverado Fire started October 26, 2020, burned about 12,466 acres, and led to evacuation orders for about 70,000 people in Irvine and about 9,500 in Lake Forest. The CPUC later fined SCE $2.4 million over conductor clearance, and in February 2025 the county board approved SCE settlements totaling $18.125 million for the 2020 Silverado and 2022 Coastal fires. In October 2020, SCE cut power to Yorba Linda ahead of Santa Ana winds as the Blue Ridge Fire pushed evacuations into the city. The Freeway Complex Fire of November 15, 2008 burned homes in Yorba Linda, Anaheim Hills and Brea. Brea saw the Carbon Fire on April 25, 2026, about 209 acres near Carbon Canyon Road.

Recent map updates add exposure on the north edge. Fullerton adopted an updated CAL FIRE map in May 2025 that raised its Very High zone from 1,186 to 1,516 acres. La Habra has 1,849 acres in the Very High zone as of March 2025. For what that means for an electrician’s work, see wildfire zones and electrical work.

Housing eras

The median home was built in 1965 in Buena Park and Garden Grove and in 2002 in Irvine. The share of homes built before 1970 runs from 2 percent in Aliso Viejo to 61 percent in Garden Grove. Counting through 1979, the central cities are older: about three-quarters of homes in Buena Park, Garden Grove, Santa Ana and La Habra were built before 1980, and 82 percent in Fountain Valley. Homes from those decades often have panels sized for fewer loads, and some may still have original branch wiring. Irvine and Aliso Viejo were built mostly after 1980 (only 21 percent of Irvine’s homes and 6 percent of Aliso Viejo’s predate 1980), with newer wiring but often tight panels once an EV charger or a heat pump is added.

Climate and load

Inland cities such as Yorba Linda, Brea and Fullerton run air conditioning longer than the coast does, and APU’s time-of-use periods matter for Anaheim homes that cool and charge an EV in the same hours. A load calculation should include cooling before a charger or heat pump goes on the same panel.

Local money

Among the cities on this site, only Anaheim’s utility pays cash rebates. As of October 2026, APU’s rebate pays up to $300 per Level 2 charger, up to $600 per networked charger if the customer also joins an available time-based rate, and up to $750 for an electric panel upgrade, subject to fund availability. OCPA’s plans (Basic Choice, Smart Choice and 100% Renewable) are rate choices, not rebates, and their prices change, so compare the current OCPA and SCE rate sheets. SCE customers in income-qualified or disadvantaged-community households can check Charge Ready Home and its current terms, and the PSPS guide covers shutoff preparation. For work types, start with panel upgrades and EV chargers.
