Conowingo Hydro Station

Conowingo was an engineering marvel when constructed more than 90 years ago and it continues to operate safely and reliably today. Learn more about the facts on the history of the dam, sediment, debris management and  how the future looks bright for Maryland’s largest source of renewable energy.

Located on the lower Susquehanna River in northern Maryland, the Conowingo Dam has served as Maryland’s largest source of clean energy for more than 90 years. Owned and operated by Exelon Generation, the Conowingo Dam currently has 11 turbines, which can produce up to 572 MW of electricity. Over the years, the Conowingo Dam has played an important role in protecting the Chesapeake Bay, supporting local and state economies and providing recreational opportunities for thousands of local residents and tourists.

The Dam also has a Visitors Center where the public can learn about the history of Conowingo, the role of hydroelectricity as a renewable energy source, and about Conowingo’s nearby recreational facilities and public access areas available for residents and tourists. These recreational activities include bird-watching, picnics, photography and more. Exelon Generation maintains several public parks as part of its Conowingo license and welcomes thousands of visitors eager to learn about local ecology every year.
