Power You Can Count On
Nuclear energy is the only large-scale power source that can be tapped in even the most extreme weather conditions, 24 hours a day, 7 days a week. Constellation’s nuclear facilities are built to withstand tornados, hurricanes, floods, heat waves and droughts, and even record-breaking winter snow and ice. During the 2014 polar vortex, demand for energy surged. Nuclear facilities performed when other plants did not.
We do this day in and day out, without emitting carbon dioxide, sulfur dioxide, or nitrogen oxides as part of the power generation process. In fact, nuclear power plants produce more than 60% of the nation's clean energy, more than all other clean-energy sources combined.
Thanks to nuclear power, Constellation makes sure electricity is there when you need it. Nuclear plants only need to be refueled every 18 to 24 months, and Constellation has the fastest refueling time in the business. Our 2021 average refueling outage duration was 22 days, 11 days better than the industry average. It's another way we achieve industry-leading reliability.
The fuel we need to keep your power on is right here, on site. We don't depend on on-time shipments, clear roads, or cooperative weather conditions. A polar vortex or extreme heat won't stop us from producing power when it's needed most.
