Backup Power Guide for Iowa: Edition 2026

Iowa's position in the heart of the Midwest makes it vulnerable to severe weather. The 2020 derecho was a wake-up call, leaving hundreds of thousands without power for weeks. Proper backup power is essential for Iowa homes.

The Derecho Threat

The August 2020 derecho was one of the most destructive storms in Iowa history, with 140+ mph winds leaving 500,000+ without power. Cedar Rapids took weeks to fully restore. This wasn't a one-time event—derechos can happen any summer.

⚡ Pro Tip for Iowa

With Iowa's low electricity rates ($0.12/kWh) and harsh winters, a natural gas generator provides the best value. Ensure your propane tank is large enough (500+ gallons) if relying on propane in rural areas.
