The UNS Electric rate increase, and what it means for solar
UNS Electric base rates held steady from 2014 until a roughly 12 percent residential increase took effect in February 2025. For homes around Kingman, Lake Havasu City, and Nogales, the logic is the same as it is statewide: rising rates make owning your power the move that pays off.

What it looks like over 25 years
A rate increase does not happen once. It compounds. The line below shows the difference between staying on the UNS Electric rate and locking your cost in with solar.

How solar caps your rate
The Arizona Corporation Commission approved this increase to cover about $330 million in grid investment after more than a decade of flat base rates. Owning solar changes your exposure to it. The power your panels produce costs the same every year, so the UNS Electric increase only applies to what you still buy from the grid, a much smaller number once your roof is covering most of your usage.
