Average U.S. nuclear capacity outages during the summer of 2024 (June 1 through August 31) decreased to about 2.6 gigawatts (GW) per day from 3.1 GW in 2023, similar to average summer daily outages in 2022. Outages this past summer were highest in mid-July and early August, averaging 3.1 GW per day and peaking at 5.7 GW on the last day of August. More recently, nuclear outages have exceeded the five-year average because of weather-related disruptions and refueling outages.
