Introduction Conventional Hydro

Hydroelectric plants harness the energy produced by flowing water, and use simple mechanics to convert the energy into electricity. Water falling from an elevated reservoir drives turbines beneath a dam to generate the power.

Because it uses water as a power source, hydroelectricity is inexpensive and environmentally friendly. However, the amount of power that can be created by hydroelectricity is limited by the volume of water held by the dam.

In the Carolinas, we use hydroelectric plants to meet peak demands at times when electricity usage is greatest, like hot summer days or cold winter nights.
