Constellation is the nation’s largest producer of carbon-free energy and sustainable solutions to millions of homes, institutional customers, the public sector, community aggregations and businesses, including three fourths of Fortune 100 companies.
Our generation fleet of nuclear, hydro, wind, and solar generation facilities powers more than 20 million homes and businesses, providing 10 percent of all clean power on the grid in the U.S. All told, our fleet is helping to accelerate the nation’s transition to clean energy with more than 32,400 megawatts of capacity and annual output that is nearly 90 percent carbon-free.
Constructed in 1928, the Conowingo Dam originally produced 252 megawatts (MW) of power, becoming the second-largest hydroelectric project in the United States after Niagara Falls. Today, the dam includes 11 turbines and can generate up to 572 MW of pollution-free electricity, powering 165,000 homes, on average. In fact, the dam's renewable energy production is greater than all other Maryland renewable energy sources combined.
The dam is also a critical player in meeting the state’s renewable energy and climate action goals and prevents 880,000 tons of greenhouse gas emissions each year, the equivalent of taking 170,000 cars off the road.
