Independent Report Confirms Constellation is Nation's Largest Producer of Emissions-Free Energy

Annual air emissions report data also shows Constellation's rate of carbon dioxide emissions is nearly 4.5 times lower than that of its next closest peer

BALTIMORE (Nov. 19, 2024) - For the 11^th consecutive year, Constellation (Nasdaq: CEG) is the nation's largest producer of clean, zero-emissions energy and boasts the lowest rate of carbon dioxide emissions among the 20 largest privately- or investor-owned power producers in the United States, according to an independent report of air emissions data.

Released today, the annual Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States report showed that the next cleanest generator among the list's top 20 privately- or investor-owned companies had nearly 4.5 times the carbon dioxide emissions rate (lbCO2e/MWh) as Constellation. With more than 23,000 megawatts of clean generating capacity, Constellation's fleet of nuclear, solar, wind and hydro plants produce about 10% of the nation's emissions-free energy. Nearly 90% of Constellation's annual energy output comes from emissions-free sources, and the company is working toward its goal to produce 95% carbon-free electricity by 2030 and 100% by 2040.

"As the nation's No. 1 producer of emissions-free energy, we are committed to ensuring our customers and communities have access to clean, reliable energy where and when they need it," said Katie Ott, vice president of Sustainability and Climate Strategy, Constellation. "The Constellation team is working to extend the lives and increase the output of our nuclear units and innovating new solutions like restarting the Crane Clean Energy Center to power the nation's critical infrastructure, including data centers, with zero-emission nuclear energy."

The emissions report benchmarks key air pollutant emissions -- including nitrogen oxide, sulfur dioxide, carbon dioxide and mercury -- from the 100 largest U.S. power producers from the year 2022. It relies upon publicly reported generation and emissions data from the U.S. Energy Information Administration and the U.S. Environmental Protection Agency and has established a clear record of the sector's environmental performance. Per the report, zero-carbon resources generated approximately 41% of U.S. electricity in 2023. Nuclear energy led the way, comprising 44% of that total and 18% of all U.S. generation.
