Not every outage is caused by weather doing something unexpected. A Public Safety Power Shutoff (PSPS) is your utility deliberately cutting power to your neighborhood — on purpose, in advance, to keep its own equipment from sparking a wildfire during dangerous wind and dryness conditions. That makes PSPS events different from a storm outage in almost every way that matters for prepping: they’re forecastable, they come with real advance notice, and they can recur multiple times in one bad wind season. If you live somewhere with wildfire risk, this is worth planning for specifically rather than lumping it in with generic “the power might go out” prep.

What a PSPS actually is

A PSPS is a preemptive, utility-initiated shutoff — not equipment failure, not storm damage, a deliberate decision to de-energize lines when high wind combined with low humidity and dry vegetation creates a real risk that an energized line could ignite a fire. In California, six investor-owned utilities have PSPS authority under CPUC oversight: PG&E, Southern California Edison, San Diego Gas & Electric, Liberty Utilities, Bear Valley Electric, and PacifiCorp. This is not a California-only phenomenon anymore — PacifiCorp runs equivalent programs in Oregon and Washington, Hawaiian Electric has launched a formal PSPS program, Puget Sound Energy and New Mexico’s PNM both operate active wildfire-driven shutoff programs, and Colorado’s utility regulator has been reviewing PSPS policy since a 2024 shutoff event. If you’re in fire country anywhere in the West, check whether your specific utility runs a program like this — don’t assume it’s only a California issue.

How much warning you actually get

Utility notification timelines are fairly consistent across providers, and it’s worth knowing the real numbers rather than a rounded guess. SDG&E’s alert program targets 24-48 hours advance notice. SCE’s initial notification target is within 48 hours of an expected shutoff, with daily updates as conditions firm up. PacifiCorp gives public-safety partners a 72-hour advance alert, but customers themselves typically get 48 hours’ notice, followed by a second alert around 24 hours out and a final notice at cutoff. The honest caveat every utility includes: notice can shrink to same-day if fire-weather forecasts change quickly, so treat the standard timeline as the plan, not a guarantee. Notifications come through phone calls, texts, emails, the utility’s app and website outage maps, and — for medical baseline and vulnerable customers — door-knock outreach in some cases.

Medical baseline programs — what they do and don’t do

If you or someone in your household depends on powered medical equipment, medical baseline enrollment is worth doing regardless of how you feel about the rest of PSPS prep. These are real programs, typically requiring a doctor’s verification, that provide an extra monthly energy allowance, bill discounts, and — the part that matters most here — enhanced PSPS alerts, sometimes including multiple calls, texts, and a physical door-knock. What medical baseline enrollment does not do is exempt you from a shutoff. It buys you more warning, not guaranteed power. If your household needs uninterrupted power for medical equipment, backup power planning is still essential — see our backup power for medical devices guide for sizing.

How long these actually last

There’s no fixed duration you can plan around — this is the part where a lot of PSPS advice oversimplifies. Industry guidance generally suggests planning for a minimum 48-hour self-sufficiency window, ideally 72 hours or more, since restoration only begins after the wind risk passes and crews finish manually patrolling every mile of affected line for damage before re-energizing — a step that adds real time beyond the weather simply calming down. In practice, events can run much longer than any single 72-hour window implies: multi-wave PSPS periods spanning weeks during a sustained bad wind season aren’t unusual for the highest-risk utilities. Plan for the 48-72 hour minimum, but don’t be surprised if a severe fire-weather stretch means rolling, recurring shutoffs rather than one clean event.

What makes PSPS prep different from storm-outage prep

The predictability is the whole advantage here — use it. A storm outage can arrive with little warning; a PSPS is preceded by a Red Flag Warning and a formal watch-to-warning notification sequence you can track in advance. That means the smart move is building your watch-list habit before fire season starts, not scrambling once a warning lands.

Building your PSPS-specific plan

1. Confirm which utility serves you and whether it runs a PSPS or equivalent program — check their website directly, don’t assume based on your state.
2. Enroll in text/email/app alerts before fire season starts, not after the first warning.
3. If applicable, enroll in medical baseline for enhanced notice (remembering it does not guarantee power).
4. Bookmark your utility’s live outage/PSPS map so you can check real-time status without waiting on a callback.
5. Build your household’s 48-72 hour self-sufficiency plan around food, water, medication cold-chain, and lighting — see our what to do during an extended power outage guide for the full playbook.
6. Plan for recurrence, not a single event — during a bad wind season, treat each PSPS as one of possibly several rather than a one-off.

Keeping the essentials running

Because PSPS events are predictable, they’re also one of the best-suited outage types for planning real backup power rather than improvising. If you’re deciding between a portable power station and a standby setup, our own how to size backup power guide walks through the math, and our sister site GeneratorAdvice.com covers how to size a standby generator and the portable vs. standby generator decision if a fixed installation makes sense for your situation. Refrigerated food and medication are usually the first casualty of a multi-day PSPS — see how to keep your refrigerator running during an outage for the practical options.

Common mistakes

• Assuming PSPS only happens in California. Oregon, Washington, Hawaii, New Mexico, and Colorado all have real programs or active policy discussions on this now.
• Treating medical baseline enrollment as a power guarantee. It’s a notification upgrade, not an exemption from the shutoff itself.
• Planning for exactly 72 hours and no more. Real events can run longer, especially in a sustained bad wind season with multiple waves.
• Not registering for alerts until a warning is already active. Enrollment before fire season means you’re not scrambling to sign up while also evacuating cold food from the fridge.
• Ignoring the watch/warning sequence. PSPS is one of the more predictable outage types — a Red Flag Warning is a real heads-up if you’re watching for it.

Recommended gear

Since PSPS windows are predictable enough to actually plan around, a properly sized portable power station for critical loads (fridge, medical equipment, lighting, phone charging) covers most 48-72 hour PSPS windows without the fuel-logistics headache of a generator, and a simple refrigerator/freezer thermometer tells you definitively whether food is still safe after an extended outage rather than guessing.

Key takeaways

• A PSPS is a deliberate, preemptive utility shutoff during high fire-risk wind/dryness conditions — not equipment failure or storm damage.
• Programs now exist beyond California — Oregon, Washington, Hawaii, New Mexico, and Colorado all have active PSPS or equivalent programs.
• Typical customer notice is around 24-48 hours, though it can shrink to same-day if fire-weather forecasts change quickly.
• Medical baseline enrollment improves your notification, but does not exempt you from the shutoff — backup power planning is still necessary.
• Plan for a 48-72 hour minimum self-sufficiency window, and expect possible multi-wave recurrence during a severe fire-weather stretch, not just one clean event.

FAQ

How is a PSPS different from a regular power outage? A PSPS is a deliberate, planned shutoff by the utility to prevent wildfire ignition, not an equipment failure or storm-caused outage. That means you get real advance notice, which a storm outage often doesn’t provide.

Does signing up for medical baseline guarantee I’ll keep power during a PSPS? No. It provides an extra energy allowance, bill discounts, and enhanced advance notice — not an exemption from the shutoff itself. You still need a backup power plan.

How long do PSPS events usually last? Plan for a 48-72 hour minimum, since restoration requires both the wind risk passing and manual line inspection before power is restored. Severe wind seasons can bring multiple, recurring shutoffs rather than a single event.

Does PSPS only happen in California? No, though California utilities (PG&E, SCE, SDG&E, and others) run the largest and most established programs. Oregon, Washington, Hawaii, New Mexico, and Colorado all have active programs or policy work underway.
