The best reliability, and more clean energy than all others combined.
Nuclear energy is the only large-scale source that can be tapped in even the most extreme weather conditions, 24 hours a day, 7 days a week. Our nuclear facilities are built to withstand tornados, hurricanes, floods, heat waves and droughts, even record-breaking winter snow and ice. During the 2014 polar vortex, demand for energy surged. Nuclear facilities performed, when other plants didn't.
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 percent of the nation's clean energy - more than all other clean-energy sources combined.
Exelon Generation makes sure electricity is there when you need it.
Nuclear energy plants only need to be refueled every 18 to 24 months, and Exelon has the fastest refueling time in the business. 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 even a natural disaster won't stop us from producing power when it's needed most.
Equipment upgrades keep Exelon Generation as reliable as it gets.
Exelon Generation spends millions each year on capital projects and upgrades to improve and modernize equipment. This ensures reliable plant operations, and enhances safety. Consistent upgrades make our nuclear plants state of the art facilities.
One way reliability is measured is capacity factor, or the amount of up-time when a plant is producing power, up to 100 percent. In 2016, Exelon Nuclear's capacity factor was 94.6 percent, the highest in the business.
Exelon Generation's reliability is powered by our people, too.
At our nuclear facilities, Exelon Nuclear employees and technical experts perform tens of thousands of work activities every year: equipment upgrades, extensive safety inspections and tests, and plant improvements. We meticulously disassemble, inspect, reassemble and test reactor components.
Uranium is abundant, low cost and powerful.
Nuclear energy uses uranium as its fuel. Uranium occurs naturally in numerous minerals found in rock, in numerous places around the world. So there’s an ample supply, and it’s relatively low cost.
Uranium is also efficient. One uranium fuel pellet – about the size of the tip of an adult’s pinkie finger – produces the same amount of energy as 126 gallons of oil, 17,000 cubic feet of natural gas or one ton of coal.
