Wyoming's outage risk is driven by severe winter blizzards, ice storms, and extreme high-wind events across the state's open plains and higher elevations, plus summer thunderstorm and wildfire-related risk; Gillette and the Powder River Basin see additional exposure to industrial-load grid stress, while Cheyenne and Casper share the broader Rocky Mountain-front pattern of sudden, fast-moving winter storms.
