July 9 (Reuters) - U.S. electricity generation hit a record high last week as an intense heatwave across much of the country boosted air-conditioning demand, according to data from the Edison Electric Institute.

Power output reached 100,996 gigawatt-hours (GWh) in the week ended July 4, surpassing the previous record of 99,445 GWh set in July 2022.

Over the past 52 weeks, U.S. electricity generation totalled 4.35 million GWh, up 2.3% from a year earlier.

"Meeting surging demand and ensuring the grid can withstand severe weather will require continued investment in America’s energy infrastructure", said EEI CEO Drew Maloney.
