This excessive heat wave continues to break records and Arizona Public Service (APS) says its customers have again made history, setting a new peak for the most energy used. Customer energy use reached 8,193 megawatts (MW) Thursday, July 20. One megawatt powers roughly 160 homes.
That's more than 1.3 million homes and businesses using electricity to keep cool during Arizona’s record heat wave.
Thursday’s energy use surpassed the all-time peak set just five days earlier on July 15. Starting July 14, APS customers recorded the seven highest peak days ever. The previous peak demand was 7,660 MW set on July 30, 2020.
“Despite historic levels of energy usage, APS and its customers experienced no issues related to power supply; and that does not happen by accident. It takes years of planning, maintaining a diverse energy mix, investing in and strengthening the electric system, and most importantly teams of people who are dedicated to keeping the lights on for customers when they need us most,” said Ted Geisler, APS president. “Arizona summers can be brutal, and APS is here to serve and ready to respond every day whether we’re faced with heat, monsoon storms, wildfires or all of the above.”
