Why Your Power Keeps Going Out This Summer

Xcel’s Public Safety Power Shutoffs Explained (And How Arvada Homeowners Can Prepare)

It’s 5:30 on a Sunday evening in July. Dinner’s on the stove, the AC has finally caught up with the afternoon heat, and then — nothing. Lights out, fridge silent, ceiling fan winding down. If that scenario sounds familiar, you’re not imagining things. One Littleton homeowner recently told our team at Mighty Pine Home Services that this exact scene played out in their house four Sundays in a row, always after 5:30 PM — one outage lasted about two hours, another stretched past twelve.

If you’re in Arvada or anywhere else along the Front Range and you’ve noticed your power feels less reliable than it used to, you’re right to notice — and there are real, documented reasons behind it. Some of it comes down to Xcel Energy’s Public Safety Power Shutoffs (PSPS), a wildfire-prevention program you’ve probably seen in the news. Some of it comes down to plain old summer heat and wind putting stress on an aging grid.

Here’s what’s actually going on, what to do about it this season, and why more of your neighbors are choosing to stop leaving it to chance.

What Is a Public Safety Power Shutoff (PSPS)?

A Public Safety Power Shutoff is exactly what it sounds like: Xcel Energy proactively cutting power to certain lines when weather conditions make those lines a wildfire risk. The trigger is a combination of strong winds, low humidity, and dry vegetation — the same recipe behind some of the West’s most destructive wildfires. If a power line goes down or arcs in those conditions, it can ignite a fire in seconds. Shutting the line off first is Xcel’s way of removing that risk entirely.

Colorado’s Public Utilities Commission doesn’t approve or deny individual PSPS events — that call belongs to Xcel. The PUC’s role is to make sure the way Xcel communicates, prepares for, and carries out these shutoffs actually protects customers, and the agency is currently in the process of writing permanent rules for how PSPS events should work going forward.

Here’s some context that might surprise you: as sweeping as these shutoffs feel, Xcel has only called a region-wide PSPS in Colorado twice, ever. The first was in April 2024, affecting roughly 55,000 customers for up to two days. The second came in December 2025, a two-part event during a bout of extreme wind and fire danger. Xcel has publicly acknowledged that early on, customers didn’t get enough advance warning and that some of the information shared during that first event wasn’t accurate — lessons they say have shaped how they’ve handled it since.

Why It Feels Like It’s Happening More Often

Two events in two years might not sound like “more often” — but Xcel’s own team has said publicly that they expect PSPS events to become a more regular part of life here, comparing Colorado’s trajectory to California, where utilities call four to five shutoffs a year on average. Hotter, drier summers and more frequent high-wind events across the foothills and plains are the reason why.

Xcel isn’t just warning people about it — they’re spending real money to try to reduce how often it happens. The utility has committed to a $1.85 billion wildfire mitigation plan running through 2027, which includes replacing bare power lines with insulated “tree wire,” inspecting roughly 50,000 utility poles, burying about 50 miles of the highest-risk lines underground, and installing more weather stations and AI-powered wildfire detection cameras across the state. If you’ve noticed a small bump on your bill — Xcel has said it works out to around $8.88 a month for the average residential customer — this plan is why.

There’s also a second, less-talked-about system worth knowing about: Xcel’s “Enhanced Power Safety Settings”. Unlike a full PSPS, which is planned and announced in advance, this is a more automatic safeguard that can momentarily cut power to a line the instant something makes contact with it — a tree branch in high wind, for example. It resets faster than a full shutoff, but it can absolutely explain some of those shorter, less predictable outages that don’t come with any warning at all.

It’s Not Just Wildfire Season — Heat Plays a Role Too

Wildfire risk gets the headlines, but it isn’t the whole story. Xcel has said it doesn’t proactively shut off power just because of heat — in fact, they’ve publicly reassured customers that they don’t plan preventive outages during heat waves, and there are documented cases of Xcel postponing already-scheduled maintenance outages specifically because a heat wave was underway and the risk to residents felt too high.

That said, heat still causes outages indirectly. Air conditioners across the metro all cranking at once puts real strain on transformers and substations, and equipment failures during peak demand are a common, if less publicized, cause of the kind of unplanned outage you might experience on a hot evening — which lines up with what a lot of us have been feeling on these Sunday nights. Xcel’s own guidance during heat waves leans on customers to help take some pressure off the grid: closing blinds during the hottest part of the day, running ceiling fans counterclockwise to push cool air down, and cutting back on non-essential electrical use in the late afternoon.

How to Prepare for the Next Outage

Whether it’s a planned shutoff or an unplanned evening outage, a little preparation goes a long way:

• Sign up for Xcel alerts. Make sure your phone number and email are current in your Xcel account so you get advance notice of planned shutoffs. If anyone in your household relies on electric medical equipment, register for Xcel’s medical-needs notification list — it gets you earlier, more direct communication.
• Know your panel. Make sure everyone in the house knows where the electrical panel is and how to safely reset a breaker.
• Keep essentials charged. Power banks, flashlights (not candles, especially during dry, windy conditions), and a battery-powered radio or weather alert are worth keeping stocked and accessible.
• Plan for food safety. A closed fridge holds temperature for about four hours; a full freezer for about 48. If you’re staring down a repeat of a 12-hour outage, that matters.
• Have a heat plan, specifically. An outage during a 90-degree evening isn’t just an inconvenience — it’s a real heat risk for kids, older adults, and pets. Know your nearest cooling center or a friend or family member’s home as a backup.
• Check in on neighbors. Especially anyone elderly, living alone, or medically vulnerable — 211 Colorado is also a good resource to point people toward for outage-related support.

The Long-Term Fix: Never Lose Power in the First Place

Here’s the honest truth: alerts, flashlights, and a charged phone will get you through a couple of hours. They don’t do much when it’s 95 degrees out, the outage stretches past the 12-hour mark, and your fridge full of groceries — or a family member’s oxygen concentrator — is on the line.

That’s the gap a whole-house standby generator is built to close. Unlike a portable generator you have to haul out, fuel, and manually connect, a whole-house system is wired directly into your home’s electrical panel through an automatic transfer switch. When the power drops, it starts itself, and your home is back up within seconds — no matter what time it happens or whether you’re even home. It runs on natural gas or propane, so there’s no gas cans to store or generator to drag out of the garage at 11 PM.

At Mighty Pine, the process is straightforward:

1. We assess your home’s actual power needs — not a one-size-fits-all sizing.
2. We recommend the right generator for your home and budget.
3. We handle fuel source, placement, permitting, and code requirements.
4. We install the unit and transfer switch, then walk you through how it works.

If a whole-house generator feels like a bigger step than you’re ready for, a good place to start is making sure the rest of your home’s electrical system is actually ready to support one — which is where our current $50 Electrical Safety Inspection comes in. It’s a low-commitment way to get a professional look at your panel and wiring before you commit to anything bigger. If you’re already planning a panel upgrade — often a smart move before adding a generator — we currently have $250 off electrical panel upgrades, and $49 off any electrical repair if something smaller needs attention first.
