Water Use in Georgia - 2005

Virtually all our consumption is evaporation from cooling towers mandated by environmental regulations.

Typical Steam Plant Water Consumption

Nuclear 0.83 gallons per KWH

Coal, oil or gas 0.78 gallons per KWH

Combined cycle 0.22 gallons per KWH

Georgia Power’s Fleet Consumption

0.6 gallons per KWH

23 gallons per day per household

Hydropower

7 % of Georgia Power’s capacity

In Georgia, evaporation from lake surface is comparable to

evapo-transpiration from vegetation that was inundated.

Lakes also provide drinking water, recreation

and for USACE, flood control and navigation support

Georgia Power considers hydropower to be non-

consumptive of water
