Renewable Energy

With a 572 megawatt capacity, it is Maryland’s largest source of renewable electricity, producing more renewable energy than all other sources combined. The Conowingo power plant:

  • Produces 1.6 million megawatt hours of electricity annually, enough to power more than 159,000 typical households for an entire year.
  • Prevents 6.5 million tons of greenhouse gas emissions – the equivalent of taking 1.2 million cars off the road.
  • Has avoided the burning of 2.8 million tons of coal in the past ten years – enough to fill M&T Bank Stadium four times.

Reliable Energy

Unlike intermittent wind and solar generation, Conowingo’s power is 24/7 and dependable. Any one of Conowingo’s 11 units can supply energy to the grid within 10 minutes to immediately respond to dramatic changes in energy demand. In a large-scale blackout, Conowingo is the first power plant called on to restart the regional electric grid. 

Muddy Run

The Muddy Run Pumped Storage Facility located further north on the Susquehanna River in Dunmore, Pennsylvania provides an additional 1,070 megawatts of generating capacity and is part of the same relicensing process as Conowingo.
