According to a new report from the nonprofit Ceres, Constellation remained at the number one spot for United States clean generating capacity this year.

For 10 years now, the company has overseen the lowest rate of CO2 emissions among the nation’s 20 largest private investor-owned power producers, and provided the largest share of carbon-free energy to boot. That is based on publicly reported 2021 air emissions data, as showcased in the annual Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States report, released this week.

Today, Constellation boasts more than 23,000 MW of generating capacity from nuclear, solar, wind and hydro plants, which all told produce approximately 10 percent of the total carbon-free energy in the United States. Nearly 90 percent of the company’s annual energy output stems from carbon-free sources and it intends to up that to 100 percent by 2040.

“After this year of record-shattering weather, it is clear that all industries must move faster to reduce emissions and lay the foundation for our clean energy future,” Joe Dominguez, president and CEO of Constellation, said. “As we transition to a clean grid, we must ensure the lights stay on in every hour of every day, and nuclear energy is the only clean energy resource that can operate around the clock in all weather extremes. Backed by the unmatched reliability of our nuclear fleet, we are continuously seeking ways to increase our clean generation capacity, while helping customers achieve their own sustainability goals through innovations such as clean hydrogen and hourly carbon-free energy matching.”

In this regard, Constellation was at the head of a major trend for power generation in the United States. Last year, zero-carbon resources were the leading source of power generation, according to the report. They provided approximately 41 percent of U.S. electricity, with nuclear power dominating the pack at 44 percent of that total, or 18 percent of all U.S. generation.
