US Electric Grid Hits Record Output During Heat Wave
The U.S. electric grid produced over 100,000 gigawatt-hours in a single week for the first time in history. The record output occurred during a severe heat wave, highlighting the grid's performance under stress.
The United States electric grid generated a record 100,996 gigawatt-hours (GWh) during the week of June 28 to July 4, 2026, marking the first time weekly electricity output has surpassed 100,000 GWh. This new record broke the previous high set in July 2022.
The record-breaking output was approximately 22 percent above the average weekly U.S. generation level. This occurred as a significant heat wave brought extreme temperatures and high humidity across much of the country, driving unprecedented demand for air conditioning and testing the grid's capacity.
Electric companies implemented measures to prepare for and manage the surge in demand. According to the Edison Electric Institute (EEI), sustained investments in modernizing and strengthening the grid allowed it to meet the record-breaking demand and maintain reliable service.
"Hitting 100,000 gigawatt-hours in a single week for the first time in history is a milestone and a preview of what the grid of the future must be built to handle," said EEI President and CEO Drew Maloney. He emphasized that meeting surging demand and ensuring the grid can withstand severe weather requires continued investment in America's energy infrastructure.
