Georgia Power gets green light for 65-megawatt battery storage system

Energy Storage News:

US utility company Georgia Power has approval from regulator Georgia Public Service Commission (PCS) for the first project in its 80MW portfolio of ‘build, own, operate’ standalone battery energy storage systems (BESS). 

The company said yesterday that approval has been granted for Mossy Branch Battery Facility, a 65MW / 260MWh asset which will be charged with electricity from the grid. Georgia Power has appointed Wärtsilä as engineering, procurement and construction (EPC) partner to the project.

Georgia Power proposed its 80MW portfolio in its Integrated Resource Plan (IRP) in 2019. IRPs are long-term planning documents that set out regulated utilities’ spending, strategy and construction intentions. 

The 2019 IRP included a 72% increase in renewable energy generation by 2024 — the addition of 2,260MW of new resources — as well as the retirement of five coal-fired power plants in the southern US state. The IRP was unanimously approved by PSC commissioners, paving the way for the utility’s more recent submission of the Mossy Branch project proposal. 

Mossy Branch will be the first standalone battery storage system on the Georgia Integrated Transmission System grid and will be located on 2.5 acres of land in Georgia’s Talbot County.
