Purchasing Green Energy– $3.50 per block, biomass– $5.00 per block, at least 50%
solar– Special Event Purchase
Option
Advanced Solar Initiative– Proposed program that
encourages solar development
– Supply agreements with independent developers and customers
– GPC does not earn a profit, but acts as a technology facilitator
– Program debut in early 2013

A Matter of Scale
Coal/Nuclear
Hydro
Solar Wind
Biomass 1 Plant ~ 1000 MW
1 Turbine ~ 3 MW 1 Installation ~ 50 MW
1 Dam ~ 45 MW
Georgia Power Peak Demand = 18,360 MW (8/10/07)
1 Unit ~ 100 MW
