Along the I-80 corridor between Cheyenne and Laramie, the wind doesn’t just blow — it closes the interstate, tips trucks, and drives ground blizzards that reduce visibility to nothing. The same hurricane-force gusts take down power lines, and homes around Casper and across the high plains can go dark in bitter cold while crews wait for conditions to let them work. Wyoming isn’t inside an RTO like SPP or MISO; it runs on the Western grid through Rocky Mountain Power and Black Hills Energy. If you’re comparing Wyoming solar quotes, the detail installers skip is that a grid-tied rooftop system shuts off during an outage (anti-islanding) unless you’ve paired it with storage — that’s the gap you fill for real backup.
Wind is Wyoming’s grid problem
Other states plan around ice or heat; Wyoming plans around wind. Sustained gusts fatigue and snap lines, blowing snow grounds the crews who’d fix them, and the state’s long rural spans mean a downed feeder near a small town can stay down for a while. The good news is that closing that gap is quieter and simpler than it used to be — no gas generator fighting the wind in the driveway.
What you actually need to keep on
Most homes overestimate this. A fridge runs about 150W, ten LED bulbs roughly 50W together, a router near 10W, and phone charging about 20W — near 300W of steady draw to keep the core of a home going. The Solar Generator HomePower 3000 (about 3,072Wh, 3,600W) carries that for one to two days and comes with panels to recharge while the grid is down. Wyoming’s strong solar resource means those panels refill fast the moment the sky clears.

For a larger home or a longer wait
To run a furnace blower and heavier loads through a longer cold-snap outage, the Solar Generator 5000 Plus steps up to 5,040Wh and 7,200W with both 120V and 240V, expandable to 60kWh.

Sort it out before a high-wind warning is in the forecast, not during the scramble afterward. Keep it charged between systems and decide ahead which loads you’ll plug in first. It’s worth checking current deals before you buy.
