SOCO-IC-1247 is a proposed 500 MW battery storage project located in Heard County, Georgia. The project, being developed by Southern Company (SOCO), entered the Southern Company (SOCO) interconnection queue on March 6, 2024, with a proposed commercial operation date of March 1, 2028. The point of interconnection is the Plant Wansley Substation 500 kV Bus. Its interconnection status is currently in the Cluster Study phase.
The development project consists entirely of battery storage, with a total capacity of 500 MW. Recent news coverage has discussed the project's potential impact on grid stability in the Southeast region.
