The Georgia Cogeneration and Distributed Generation Act of 2001 allows residential electricity customers with photovoltaic (PV) systems, wind-energy systems or fuel cells up to 10 kilowatts (kW) in capacity, and commercial facilities up to 100 kW, to connect to the grid. The aggregate capacity of distributed generation systems is limited to 0.2% of a utility's system peak demand from the previous year.
Interconnected customers must comply with all relevant national standards, including those established by the Institute of Electrical and Electronic Engineers (IEEE), Underwriters Laboratories (UL), and the National Electrical Safety Code (NEC). Furthermore, the Georgia Public Service Commission (PSC) may adopt additional safety, power-quality and interconnection requirements. There is no provision in Georgia's interconnection standards requiring customers to install a manual external disconnect device. Utilities may not require additional tests or additional liability insurance.
Check your utility's website for further interconnection rules. Southern Company’s Distribution Interconnection Pollicy is found here.
