Georgia Power is seeking approval from state regulators to close units at two coal-fired power plants, Kallanish Energy reports.

The Atlanta-based company has asked the state’s Public Service Commission for approval to close all four units at its 865-megawatt Plant Hammond near Rome, Georgia. It also wants to close one unit at its Plant McIntosh near Rincon in southeast Georgia.

There was no timetable for the proposed closures.

The company also said it plans to boost renewable energy by 1,000 megawatts in the next few years. That would boost the company’s renewable portfolio to 4,000 MW. If approved, renewables would provide 18% of Georgia Power’s portfolio by 2024.

Those plans are contained with the company’s 20-year integrated source plan that is updated every three years. The plan must be approved by the state commission.

The plan also calls for removing two dams on the Chattahoochee River near Columbus in southwest Georgia, and a third dam on a creek in northeast Georgia. Those hydroelectric facilities are not is use, the company said.

The plan also includes energy efficiency targets, with programs designed to reduce peak demand by roughly 1,600 MW by 2022. That is about 10% of the company’s current peak demand.

Georgia Power also acknowledged its coal-fired Plant Bowen and its units 1 and 2 near Cartersville are under “continued economic pressure.”

The company also pledged to close all of its coal ash ponds in full compliance with federal and state regulations. The company has about 2.5 million customers.
