Kris Mayes issues urgent warning as Arizona faces unprecedented electric grid strain from summer heatwave.
PHOENIX, AZ – Arizona Attorney General Kris Mayes has issued a formal advisory to residents and utility providers Monday as the state contends with what experts describe as an unprecedented strain on its electrical grid. The warning comes amid forecasts of record-breaking temperatures above 115°F, sparking concerns over rolling blackouts across Maricopa, Pima, and Pinal counties. Mayes urged immediate conservation measures, citing risk of destabilization to critical infrastructure without coordinated public response. Utility companies confirm they are implementing emergency protocols while monitoring system load every 30 minutes. The advisory will remain active through Thursday, pending National Weather Service updates on sustained heat dome expansion. This announcement follows a series of legislative hearings held earlier this month regarding grid resilience under prolonged climate stress.
