Hydro

We devote great effort to preserving the environment by mindfully managing its water resources. We are one of the largest water managers in the state, with 11 company-owned lakes and 14 hydroelectric plants that produce emission-free electricity. The company’s reservoirs contain more than 157,000 acres of water and provide more than 3,500 miles of shoreline for the use and enjoyment of the public. The careful management of these resources helps provide drinking water, recreation and wildlife and fish habitat.

How Clean Water Comes Out of Plants

Water discharges from our generating facilities meet all local, state and federal regulations for water quality standards before returning to rivers, lakes and reservoirs. Water treatment systems assure all discharges are protecting these water bodies and that the quality of water is maintained to support a healthy aquatic community and drinking water system.

Volume of Water Used

Water is a vital component for electricity generation. We depend on a large quantity of water to create power and cool our plants. About half of the water withdrawn nationally is for thermoelectric power production. However, it is equally important to know that approximately 95 percent of that water goes back into the river or lake and is available for downstream uses.
