Hydropower

Clarence Cannon Power Plant

Why is Clarence Cannon Power Plant an Exceptional Resource?

About 1/4 of the nations hydroelectricity is derived from the U.S. Army Corps of Engineers facilities.

Hydropower plants are responsive and can be brought online to add power to the distribution grid in minutes to meet a need, where nuclear or fossil fuel power plants can take hours to power up. Oil, coal, or nuclear power takes a day or more to power up and be brought online.

Clarence Cannon Power Plant is a peaking plant (designed to supply dependable power during hours of "peak" daily demand), which helps reduce energy shortages.

During 2004, Clarence Cannon Power Plant was available to meet peak loads 98.85% of the time.

Clarence Cannon Power Plant can generate electricity at all hours of the day.

The water used to generate electricity is renewable.

Clarence Cannon Power Plant provides enough electricity annually for 20,000 households.
