3. Confusing Terminology
“Water Use” is used interchangeably with
“Withdrawals” and “Consumption”
Consumption = withdrawal – returned
water
Consumption measures the true impact on
downstream demands

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

7. 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

8. Georgia Power’s Fleet Consumption
0.6 gallons per KWH
23 gallons per day per household

9. 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
