Constellation’s Carbon-Free Nuclear Fleet Ran at Near 100% Capacity During Hottest Summer on Record
Sept. 21, 2023
While wildfires, hurricanes and extreme heat battered Americans from coast to coast during the hottest summer in Earth’s recorded history, Constellation’s carbon-free nuclear units ran nearly 100% of the time, powering more than 15 million homes and businesses.
Constellation’s 21 reactors at 12 sites from the Midwest to the Mid-Atlantic and Northeast operated at 99.4% during the months of June, July and August. That near-perfect reliability helped Constellation power the equivalent of 15 million average American homes through a growing number of extreme heat days– all without adding any harmful emissions to the environment.
