Extreme Heat Wave Causes 243% Power Price Surge in U.S.

A heat wave across the central and eastern U.S. is expected during the July 4 weekend, with temperatures reaching up to 105°F (40.5°C). PJM, the largest U.S. power grid operator, announced a federal alert to reduce electricity consumption. Wholesale spot electricity prices increased by over 243% in New England and 101% in New York City, while Midwest prices rose nearly 55% and Mid-Atlantic prices by 45.6%. This surge in prices coincides with record electricity demand for air conditioning as humidity levels rise.
