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
