2025 in context
2025 in Carpinteria, in its own numbers.
No wind shutoff minutes in Carpinteria in 2025. Edison's report shows 325.2 minutes in 2025, about 5.4 hours, over 3.4 outages per customer; the largest cause was equipment failure (a transformer, switch or line failing in service), 48.0% (Edison, City of Carpinteria, p. 5).
That is longer than Carpinteria's three years before, 189.9 to 257.6 minutes, with no shutoffs in it (Edison, City of Carpinteria, p. 4).
Edison reports the unincorporated 1st District separately. The largest share of the unincorporated 1st District's 2025 time was Edison's wind shutoffs: 44.4% of 457.0 minutes (Edison, Unincorporated Santa Barbara County, 1st District, p. 5). The rest comes to about 254 minutes, about 4.2 hours, derived from Edison, Unincorporated Santa Barbara County, 1st District, p. 4. For comparison, total minutes in 2022 to 2024 were 161.2 to 299.1 minutes. Summerland is in that district; the board shows it once, under Montecito.
For the regional picture: across Edison's whole system, 15 of 2025's 21 major event days were in January, 13 of them wind shutoffs, and without those days the average Edison customer lost 116.37 minutes, about two hours (Edison 2025 report, Tables 1 and 2, p. 3 and p. 4).

Where this fits
Carpinteria and Summerland on the board.
This page is one place on County Line's Power Outage Board, the outage record for every town in the company's service area across Ventura, Los Angeles and Santa Barbara counties.
For the electrical work County Line does in Carpinteria and Summerland, see the Carpinteria and Summerland service area page. For backup power, start with standby generators, then wind shutoffs, heat wave outages and what stays on.
Reading the record
What do the minutes mean?
The minutes are Edison's SAIDI figure: the total minutes the average customer in that town was without power during the year, counting every outage longer than five minutes. Edison counts its wind shutoffs and major storm days in it and leaves out scheduled maintenance outages. Outages per customer (SAIFI) is how many of those outages the average customer had.
What does "without wind shutoffs" mean?
The without wind shutoffs figure is derived from Edison's own figures: the town's 2025 minutes times one minus the share Edison attributes to wind shutoffs on its causes chart (p. 5 of each city report). Thousand Oaks: 1,814.5 minutes times 17.0% is about 308 minutes. Edison does not publish that figure itself.
Why was 2025 so much longer than other years?
2025 ran long mostly because of wind shutoffs in January. Edison had 21 major event days in 2025 and 15 of them were in January, 13 of them wind shutoffs (Edison 2025 report, Table 2, p. 4). Without those days, Edison's 2025 average was 116.37 minutes, about two hours.
Has Edison shut off power in the last 12 months?
No Edison wind shutoff de-energized a customer in Ventura County. Edison notified Ventura County public safety partners during the November 9, 2025 and September 25, 2026 events, and switched nothing off there. In Los Angeles County, Edison de-energized circuits in the August 25 and September 25, 2026 events. None of them is on Edison's 2025 circuit lists for Agoura Hills, Calabasas, Hidden Hills, Westlake Village, Malibu, Santa Monica, Beverly Hills or unincorporated 3rd District (Topanga). In Santa Barbara County, Edison switched off circuits in events including July 15, July 22, August 25 and September 25, 2026.
Why do some Los Angeles neighborhoods show LADWP figures?
Pacific Palisades, Bel Air, Brentwood, Encino, Studio City, Sherman Oaks, Tarzana and Woodland Hills are City of Los Angeles neighborhoods served by the Los Angeles Department of Water and Power, not Edison. LADWP reports one figure for its whole system, so those pages show that figure.
What keeps a house on when the grid goes off?
A standby generator with an automatic transfer switch carries a house for days on natural gas or propane. A battery covers the first hours silently. Designed together, with solar and the panel, they make a residential microgrid. County Line designs, installs and services all of it.
