Georgia Power begins Twiggs battery storage project, expands statewide plans
Georgia Power announced Monday that it has started construction on a new 200-megawatt battery energy storage system in Twiggs County.
A battery energy storage system, often called BESS, is a large-scale setup that stores electricity for later use.
Renewable energy sources such as solar and wind can present challenges when the sun isn’t shining or the wind isn’t blowing. But with battery storage systems, extra energy can be stored from these sources when production is high and released when production is low or demand exceeds supply.
“With increasing concerns about climate change and environmental sustainability, communities and utilities are pushing towards renewable energy sources ...,” Georgia Power’s website reads. “Battery storage systems are designed to ... (store) excess energy generated during peak production times and release it when production is low, or demand is high. This capability promotes a steady and reliable supply of electricity, regardless of the variability in renewable energy generation.”
The Twiggs BESS is adjacent to an existing solar facility and will be constructed by Crowder Industrial Construction, LLC. It is projected to be finished in 2027, according to a news release from the company
In addition to the Twiggs County site, construction is underway at four battery storage facilities in Bibb, Cherokee, Floyd and Lowndes counties. These sites will total 765 MW across the state, with expected completion in 2026, according to the release.
All five projects were selected through competitive processes resulting from the 2023 Integrated Resource Plan Update and were approved for construction by the Georgia Public Service Commission on Sept. 4, 2025, according to the release.
“With the construction of the 200 MW BESS in Twiggs County, we will be able to better serve our existing customers and support Georgia’s growth,” said Rick Anderson, senior vice president and senior production officer for Georgia Power. “As we expand our energy mix to include more renewable sources, these batteries will play an invaluable role in helping to ensure reliability and flexibility, particularly when renewable sources are not available.”
Georgia Power is seeking approval for 10 new battery storage facilities totaling 3,022.5 MW and two solar-plus-storage systems totaling 350 MW as a part of an All-Source Requests for Proposals, according to the release.
Site selection was based on deployment capabilities, including the potential to add tot existing company plant sites, on other company-owned land and at locations near existing substations, according to the release.
The utility is also requesting bids for 500 MW of additional energy storage with at least two hours of storage discharge, according to the release. Managed by Ascend Analytics, the RFP will consider standalone storage and storage paired with renewables. The projects are targeted to be online by 2031, with bids due in early 2026.
