What drives Arizona utility bills
Cooling is Arizona's larger weather load: a normal July-to-June brings 2,861 cooling against 2,160 heating degree days. Cooling peaked in Aug 2025, heating in Jan 2026.
Electricity supplied 66.8% of Arizona home energy in 2024, natural gas 20.6%. Small-scale solar supplied 8.6%; the kWh above are grid purchases, so a home with panels buys less.
Arizona Public Service Co sold 38.5% of Arizona's 2024 residential electricity, Salt River Project 37.9%.
