US Heat Wave Triggers Grid Emergency Orders Across Mid-Atlantic and Midwest

A severe heat wave across the eastern and central United States has triggered federal emergency grid actions and operator-level demand management across Mid-Atlantic, Midwest, and Mid-South states. PJM, the largest US grid operator, has escalated emergency procedures to avoid rolling blackouts as heat-driven demand strains supply, with additional operators including NYISO and MISO referenced. The US Department of Energy is referenced in connection with the grid response, with Energy Secretary Chris Wright named in reporting alongside references to the Federal Power Act. Extreme temperatures of around 113 degrees Fahrenheit are reported, with approximately 160 to 180 million people under heat alerts across 13 to 30 states. No specific facility damage, sustained outages, or insured loss figures have been disclosed.
