Exelon Generation PA Nuclear Plants Operate at Full Power During Extreme Heat

All three Exelon Generation Pennsylvania nuclear plants provided around-the-clock, carbon-free electricity for five million homes and businesses during heat wave, keeping energy market prices stable

KENNETT SQUARE, Pa. (July 23, 2019) — While the sun beat down on Pennsylvania over the weekend, sending temperatures and energy demand soaring, Exelon Generation's three Pennsylvania nuclear plants operated at full power, producing enough carbon-free electricity to keep five million homes and businesses safe and cool. That predictable, sustained energy production helped keep prices stable throughout the heatwave.

"Our zero-carbon nuclear energy facilities remain online when customers need us most, during extreme weather," said Exelon Generation Chief Nuclear Officer Bryan Hanson. "I want to thank the thousands of men and women working at our plants who kept our fleet operating during this period of high electricity demand. Our nuclear facilities are among the safest and most reliable in the country because of our dedicated, highly trained employees."

Carbon-free nuclear energy not only provides the electricity needed for air conditioning during extreme heat, it does so without releasing the harmful carbon emissions like those from fossil fuel plants.  The release of harmful carbon emissions makes air quality worse for seniors and others at risk of health problems related to air pollution in Pennsylvania. Always-on nuclear energy reduces the need for carbon-emitting peaker plants to come online during periods of high demand, which can increase market prices for electricity.

Exelon Generation's three Pennsylvania nuclear plants -- Limerick Generating Station, Peach Bottom Atomic Power Station and Three Mile Island Generating Station -- were online 95.8 percent of 2018, including during extreme weather events.

More than 38 percent of Pennsylvania's electricity is generated by nuclear energy. In fact, 93 percent of Pennsylvania's carbon-free power is produced by nuclear energy facilities, preventing the average annual equivalent of eight million cars' worth of carbon dioxide from entering earth's atmosphere.

Summer resiliency and reliability requires year-long planning, preparation and maintenance. Exelon Generation workers spend months ensuring that backup generators and spare equipment is ready for extreme weather. This spring, operators and maintenance personnel inspected mechanical systems, tested electrical equipment, and properly aligned plant systems to prepare all Exelon Generation-operated facilities for extreme temperatures. These efforts are in addition to the many equipment upgrades and "summer readiness" maintenance activities performed during refueling outages.

All of Exelon Generation's 22 reactors remained online during the recent heat wave that hit across the country.
