Your phone buzzes on a Tuesday afternoon while you're at work. It's not a text from a friend. It's an alert from your utility company, warning that a shutoff could hit your neighborhood within the next 48 hours. If you've lived in California through a few fire seasons, you already know what comes next: the guessing game of whether your street actually loses power, and for how long.
A PSPS power outage is different from the outage that knocks out your block when a transformer blows. It's planned. Your utility shuts the lines off on purpose, before wind and dry brush turn a spark into a wildfire, and it can last anywhere from a few hours to several days.

What Is a PSPS, Exactly?
A Public Safety Power Shutoff, or PSPS, is a planned outage a utility starts on purpose to keep its power lines from sparking a wildfire during dangerous weather. It's not a repair, and it's not an accident. It's a decision, made ahead of time, to cut the risk before it becomes a fire.
In California, three big investor-owned utilities run these programs: Pacific Gas and Electric (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E), along with a few smaller providers. The California Public Utilities Commission (CPUC) has found that electrical infrastructure has been linked to roughly half of the state's most destructive wildfires, even though power lines cause a much smaller share of wildfires overall. That's the logic behind the entire PSPS strategy: an old line snapping in high wind does far more damage than the inconvenience of a planned blackout.
Utilities watch for a specific combination of conditions before calling a shutoff: low humidity, forecasted high winds, dry vegetation near the lines, active Red Flag Warnings, and what crews are actually seeing on the ground in real time. The CPUC also ranks neighborhoods by wildfire risk, and homes sitting in a Tier 2 (elevated risk) or Tier 3 (extreme risk) zone are far more likely to see their power cut than someone a few miles away in a lower-risk area.
When Is PSPS Risk Actually Highest in California?
PSPS risk isn't spread evenly across the year. It starts climbing in July and peaks between September and November, when the state's driest vegetation collides with its strongest offshore winds. In Northern California, those are the Diablo winds. In Southern California, they're the Santa Ana winds. Both push hot, dry air down from inland areas toward the coast, and both have shown up during some of the state's worst wildfire outbreaks.
That doesn't mean every fall brings a shutoff. PG&E's own event records show real variation: some events have lasted a single day, others have stretched close to four days. What that tells you is that "PSPS season" is really about elevated probability, not a guarantee. You're not trying to predict the exact week your power goes out. You're trying to make sure you're ready whenever it does.
How Much Warning Do You Actually Get Before a PSPS?
The honest answer is: it depends, and often less than you'd like. Utilities try to give advance notice once a weather system starts looking dangerous, but the final call, the one that actually confirms your power is going off, often comes just hours before it happens, because wind and humidity forecasts can shift right up until the event.
Here's roughly how the timeline tends to unfold:
| Stage | Typical Timing | What to Do |
|---|---|---|
| Pre-season | Before July | Register for utility alerts, check your CPUC Tier status, apply for Medical Baseline if it applies to your household |
| Watch | Several days out | Monitor Red Flag Warnings and start topping off any backup power |
| Warning | Roughly 24–48 hours out | The utility narrows down the affected area; charge everything to full |
| Final confirmation | Often just hours before | Ground conditions confirm the shutoff; this is your last real window to charge up |
| During | Hours to several days | Ration power by priority and keep an eye on solar output |
| Restoration | After weather clears | Crews have to physically walk every de-energized mile before turning it back on |
That last stage catches a lot of people off guard. The power doesn't come back the moment the wind stops. It comes back once someone has confirmed no branch fell across the line.
What Actually Happens to Your Power During a Multi-Day PSPS?
If your home has a standard rooftop solar system with no battery, here's something that surprises a lot of homeowners: it shuts off the second the grid does. That's not a malfunction. It's required.
Most residential solar systems are grid-tied, which means they're wired to feed extra power back into the utility's lines. When a line goes dark for a PSPS, the system has to stop sending electricity into it immediately, so a crew inspecting or repairing that line doesn't get hurt by power coming from your roof. This safety behavior is called anti-islanding, and it's built into the inverter by design, not something you can just switch off.
There's a second problem specific to wildfire season: smoke. Heavy smoke overhead cuts down the sunlight actually reaching your panels, right at the moment you'd most want a full charge. So even a home with solar and a battery can see reduced output during the exact week it matters most.
A power station that isn't wired into your home's grid connection at all sidesteps this problem completely. It charges from whatever source you plug it into, independent of whether the neighborhood grid is live.
How Should You Size Backup Power for a PSPS?
Sizing backup power for a PSPS power outage isn't really a question of "how many watts." It's two smaller questions: how many days do you need to cover, and which devices actually can't go dark?
Start with a simple priority list:
Tier 1 covers the things that matter no matter what: your phone, a router or modem so you can still get alerts, one light source, and any medical equipment your household depends on — for a CPAP machine, see how to size CPAP backup power.
Tier 2 is usually the refrigerator, which draws more than you'd expect the moment its compressor kicks on — see how long a fridge stays cold without power, and there's more on the compressor surge itself below.
Tier 3 is comfort: a fan, a laptop, maybe the TV.
How that priority list turns into an actual setup depends on your living situation:
| Household Scenario | Priority Devices | Realistic Setup |
|---|---|---|
| Apartment or studio, short outages | Phone, router, one light, medical device | A compact power station |
| Family home, multi-day outage | All of the above, plus fridge and some lighting | A higher-capacity station |
| Rural or high-risk area, week-plus, smoke-prone | All of the above, plus charging redundancy | A higher-capacity station paired with a solar panel |
Zooming out a level further, most households land in one of three tiers:
| Tier | Setup | Best For | Recharge Plan |
|---|---|---|---|
| Basic | GEYOTO N300 | Apartments, short PSPS windows, a single medical device | Pre-charge via AC before the event |
| Extended | GEYOTO N1000 | A family home running a fridge plus essentials for a few days | Pre-charge via AC (0–80% in 43 minutes) |
| Multi-Day | GEYOTO N1000 + S200 solar panel | Rural or high-risk areas facing week-plus events | Solar as the daily top-up, AC as the pre-event fill |
Here's why recharge speed matters as much as total capacity: go back to that warning timeline. If your final confirmation only comes a few hours ahead, you need a station that can actually fill up in that window, not one with a big battery sitting half-empty. The N300 runs a 300W Pure Sine Wave output with a 500W Peak for short surges, and charges at 550W.

The N1000 runs an 1800W Pure Sine Wave output with a 3000W Peak, charges at 2400W, and can go from 0 to 80% on a wall outlet in 43 minutes, genuinely useful when you find out at 2pm that the power is going off at 6.

For multi-day coverage without a wall outlet, the N1000 also takes up to 800W of solar input, which is where the S200 panel comes in for the Multi-Day tier — a fitting match given its Every Ray Counts design, since smoke haze is already cutting into the sunlight you're working with. The N300 pairs with the smaller S100 panel, built around that same Less Setup, More Sunshine idea: quick to deploy for topping off a compact setup between outlets.

Either way, the goal isn't to replace your utility connection for a week. It's to cover your household's non-negotiables until the lines come back on. That's the thinking behind the N1000's positioning as an All-in-One: One Station, Fully Loaded setup — built to handle the fridge, the medical device, the router, and the lights together, whatever a multi-day shutoff throws at it. The N300 takes the opposite approach to the same problem, true to its Grab and Go design: something compact enough to toss in a bag the moment your phone buzzes with a Watch alert.
What Are the Real-World Limits of Battery Backup During a PSPS?
A power station will not replace your utility connection for a week if you don't have a charging plan behind it. That's worth saying plainly instead of burying it in fine print.
A few things affect real-world performance. Converting stored battery power into the AC power your outlets use isn't perfectly efficient, so you lose a small amount in that conversion every time. A refrigerator's compressor also draws a real spike of power the moment it kicks on, well above what it needs once it's running steadily, which is why rated output and peak output are two different numbers worth understanding before you buy — more on what 1024Wh actually means for a fridge specifically. Running several devices at once shortens your runtime faster than most people expect, since every device is pulling from the same battery at the same time. Solar charging is capped by daylight hours to begin with, and wildfire smoke can cut it further, right when you need it most. And AC charging speed tapers as a battery gets closer to full, the same way phone fast-charging slows down near 100%, so don't assume the last stretch fills as fast as the first.
Common Mistakes Californians Make When Prepping for a PSPS
A few patterns show up again and again when people get caught off guard by a shutoff:
- Waiting for a Red Flag Warning to start charging. By the time the warning hits, you're racing the clock. Keeping backup power topped off through the whole July–November window removes that pressure entirely.
- Assuming rooftop solar means automatic backup. As covered above, a standard grid-tied system shuts down with the grid unless it's paired with a battery and the right hardware.
- Sizing around total capacity alone. A station that's "big enough" on paper can still trip if a single device's startup surge exceeds its peak output, not just its running wattage.
- Not signing up for Address Alerts or Medical Baseline until a shutoff is already happening. Both are meant to be set up in advance.
- Relying only on solar with no backup charging plan for overcast or smoky days, when panel output can drop well below what you're counting on.
A Practical PSPS Preparedness Checklist
Before fire season ramps up, work through this list once:
- Sign up for alerts with your utility (PG&E, SCE, or SDG&E)
- Check your address against the CPUC's fire-threat Tier map
- Register for Medical Baseline if anyone in your household depends on powered medical equipment
- Keep your backup power charged through the July–November window, not just when a warning hits
- Run one full test before fire season starts, so you're not learning your setup during an actual shutoff
- Know your device priority list ahead of time
- Have a car-charging or solar backup plan ready for smoky or multi-day scenarios
Building Your PSPS Backup Power Plan
The real question isn't how many watts you have sitting in a box. It's how many days you need to cover and which devices in your home genuinely can't go dark.
If that's a phone, a router, and a medical device for a short window, the N300 covers that without asking you to think much harder about it. If it's a fridge running alongside the essentials for several days at a stretch, the N1000 is built to carry that load, and adding the S200 solar panel turns a multi-day PSPS from a math problem into something you don't have to think about at all. Match the tier to your household before fire season starts, not during the Watch alert. The same day-count-and-priority-list approach works for any planned or storm-driven outage — if you're weighing backup power for hurricane season too, see our hurricane backup power plan for the same sizing logic applied to a different trigger.
FAQ
How much notice will I actually get before my power is shut off?
Sometimes a few days, sometimes just hours. Utilities try to alert you early once a weather system looks dangerous, but the final confirmation often comes close to the event itself, so it's worth staying charged up through the whole watch period rather than waiting for certainty.
Can a portable power station realistically run a refrigerator during a multi-day PSPS?
Yes, as long as you size for the compressor's startup surge, not just its running wattage, and pair it with a charging plan, whether that's solar, a car charger, or rationed AC top-ups.
Will my rooftop solar keep working during a shutoff?
Not unless it's paired with a battery and the right hardware to disconnect from the grid safely. A standard grid-tied system shuts off the instant the grid does, by design.
How do I find out if my home is in a high fire-risk area?
Check your address against the CPUC's wildfire risk Tier map. Homes in Tier 2 or Tier 3 zones are far more likely to see a PSPS than homes outside those areas.
A PSPS power outage isn't really about the power going out. It's about whether you'd already decided, before your phone buzzed, how many days you needed to cover and what couldn't go dark. Get that answer sorted before fire season starts, match it to a setup that can actually charge fast enough to matter, and the next Watch alert becomes an inconvenience instead of a scramble.
