Public Safety Power Shutoff and the house
A Public Safety Power Shutoff (PSPS) is a utility turning off lines so the grid is less likely to start a wildfire. The California Public Utilities Commission describes it as a last-resort de-energization. It is not Oregon R327. Pacific Power, which serves parts of Oregon and California, says customers typically get about 48 hours’ notice. Plan the garage opener, the well pump, the fridge, medical devices, and the smoke-ready room. Do not paste a utility map onto a drawing.
You are in the garage looking at an electric opener, then at a well pressure tank in the crawl space, then at a phone alert. When the line goes dead, the opener and the pump go with it. That is the house during a PSPS. It is not a permit comment.
This page is the utility outage, not a product listing. Do not paste a utility map onto a drawing.
Why it matters
CPUC says PSPS can reduce utility-associated wildfire and still leave communities and essential facilities without power. That second harm is the point of this page. A Class A roof does not run the well. A listed vent does not open the garage. People also treat rooftop solar as a guaranteed island. CPUC’s FAQ says most arrays shut down so they do not back-feed a dead grid.
How it works
Electric lines and equipment can ignite vegetation in wind. CPUC cites Public Utilities Code sections 451 and 399.2(a) as the authority for investor-owned utilities to shut off power to protect public safety. Named IOUs include PacifiCorp (Pacific Power).
Pacific Power lists the factors it watches: dry fuels, high sustained winds, extremely low humidity, forecasts, population density, on-the-ground observation, and input from local public-safety and health agencies. No single factor, such as wind alone, forces a shutoff on that page.
Restoration is not a switch. Pacific Power patrols in daylight, inspects for damage and hanging debris, repairs, then restores.
The paths
| System | What a shutoff does | What to do before the alert |
|---|---|---|
| Garage door | Electric opener stops | Confirm a manual release. CPUC: move the car out if you cannot operate it by hand. See garage doors. |
| Well / booster pump | Water stops if the pump is electric | CPUC: municipal water and gas should stay on; well systems are the exception. Store water. See rural water. |
| Fridge / freezer | Warmth | Know how long food lasts. Ice, cooler, or a planned generator. |
| Medical devices | Battery drain | CPUC and Pacific Power: have a year-round outage plan. Enroll in the utility’s medical/accessibility program. |
| Solar | Usually off | CPUC: most systems power down. Ask the installer about islanding and batteries. See solar on a Class A roof. |
| Portable cleaner | Silent | Smoke-ready home needs power. A battery station is a different product. |
| Generator | Optional backup | CPUC: fire and carbon monoxide hazards. Do not back-feed the grid. Utility and a licensed contractor before you hard-wire. |
1. Get on the list. Pacific Power: keep account phone, email, and text current. The company notifies by call, email, text, social media, and media advisories. Typical customer notice is 48 hours. Public-safety partners about 72 hours. Weather can compress that.
2. Walk the house once, in daylight. Manual garage release. Well or booster. Fridge. CPAP or oxygen concentrator. Electric range. Garage EV. CPUC: charge the EV when you get notice; unplug it for the event; if the door is electric, move the car out.
3. Do not assume solar is backup. Ask the installer. If you add a battery or a generator tied to the panel, CPUC says contact the utility first.
4. This is not R327. Hardening the roof and the vents still matters on a windy day. It does not keep the well running. Do both jobs.
What people mix up
- Treating PSPS as a building-code inspection.
- Treating rooftop solar as an automatic island.
- Leaving the car in a garage you cannot open by hand.
- Running a generator in a closed garage.
- Scraping the utility map into a site plan.
How to check
- Open your utility’s PSPS page. For Pacific Power: public-safety power shutoff.
- Open CPUC’s PSPS page and the FAQ.
- Confirm medical-baseline or accessibility enrollment if you use a powered device.
- Test the garage manual release.
- Do not treat a Watch polygon on a map as a construction setback.
Limits
This page does not dispatch crews and does not reprint a map. CPUC FAQ cost ranges for batteries and generators are not quoted here because they rot. FireApproved is not a utility. PGE and other Oregon IOUs publish their own pages. Open the one on your bill.

Questions
Is a PSPS a building-code path?
No. The California Public Utilities Commission describes PSPS as a temporary shutoff to reduce the risk of fires caused by electric infrastructure. Oregon R327 is construction. Pacific Power’s page is outage planning. They are not one document.
Will my well and garage door still work?
CPUC’s PSPS FAQ says water and gas should stay on during a shutoff, except where water needs an electric pump, including well systems and some high-rises. An electric garage-door opener will not run. CPUC says if you cannot operate the door manually, move the car out before the shutoff.
Will rooftop solar keep the lights on?
CPUC’s FAQ says most solar systems automatically power down during a shutoff so they do not back-feed a dead grid. Some systems can island. Check the installer. A battery or a generator is a different product. Contact the utility before you tie backup into house wiring.
How much notice will I get?
Pacific Power says customers will typically receive 48 hours’ advance notice, and the company aims to alert public-safety partners about 72 hours ahead. Worsening weather can force faster action. Update the phone and email on the account.
