The utility will buy more than 10 times the amount of solar electricity it now gets from solar farms and rooftop equipment by 2017, company officials said.
Georgia Power disclosed the plan in a proposal Wednesday to the state Public Service Commission, which must approve it. Utility officials say customer bills would not be affected.
Factors in the decision include declining solar costs, pressure from customers, the solar industry and some utility regulators, company officials told The Atlanta Journal-Constitution.
"We see this as a good first step toward increasing Georgia's infrastructure," said Jessica Moore, executive director of the Georgia Solar Energy Association.
Georgia Power won't build or operate the solar farms or rooftop panels to supply the sun-power boost, officials said. Rather, the utility will buy most of the power from large "utility-scale" solar farms. It will buy a smaller amount from homes and businesses with solar systems.
Plans call for lining up suppliers during the next couple years and ramping up purchases from 2015 through 2017.
