Georgia Power Initiates Construction of 200 MW Battery Storage System Near Macon to Enhance Energy Reliability

Georgia Power Begins Major Battery Storage Project

Georgia Power has officially kicked off construction for a new large-scale Battery Energy Storage System (BESS) in Twiggs County, just southeast of Macon, Georgia. The project, announced on October 20, 2025, will have a capacity of 200 megawatts (MW), significantly enhancing the utility's ability to meet energy demands and ensure reliability for its customers.

Overview of the Project

This ambitious initiative was approved by the Georgia Public Service Commission (PSC) on September 4, 2025, following a thorough competitive selection process as part of Georgia Power's 2023 Integrated Resource Plan (IRP) Update. Located adjacent to the existing Twiggs County Solar facility, the project signifies Georgia Power's commitment to integrate renewable energy sources and strengthen the overall resilience of Georgia's electric grid.

The BESS will be designed to swiftly dispatch stored energy over a four-hour period, effectively responding to fluctuations in consumer demand. One of the primary benefits of such systems is their capacity to store excess energy generated during low demand periods for use when consumption is higher, notably during chilly winter mornings when solar power production is insufficient.

Enhancing Grid Reliability

Rick Anderson, Senior Vice President and Production Officer for Georgia Power, expressed the strategic importance of this development. He emphasized that collaboration with the Georgia PSC and various stakeholders plays a critical role in investing in a reliable power grid. He stated, “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.”

The Twiggs BESS project is spearheaded by Crowder Industrial Construction, LLC, with an expected completion date set for 2027. In addition to this project, Georgia Power is also actively constructing four other BESS facilities across the state, which will collectively add around 765 MW to the grid, with planned completions later in 2026.

Future Developments

Georgia Power’s commitment to enhancing energy storage is also evident in its All-Source Request for Proposals (RFP). The utility is seeking approval for ten new BESS facilities that would add an impressive capacity of 3,022.5 MW. These facilities will contribute not only to improved energy reliability but also to the efficiency of renewable energy deployment.

Among these planned facilities, there are also proposals for state-of-the-art solar systems paired with energy storage capabilities, amounting to a combined capacity of 350 MW. The strategic selection of sites for these projects considers existing company plant sites and nearby substations to maximize deployment efficiency.

Moreover, Georgia Power is seeking bids for an additional 500 MW of Energy Storage Systems (ESS) with a minimum two-hour discharge duration, marking a proactive approach to augmenting their energy storage capabilities further. This RFP, managed by Ascend Analytics on behalf of Georgia Power, is set to close for bidding by early 2026.

Conclusion

The advancements initiated by Georgia Power demonstrate a focused effort to transition towards a more sustainable and resilient energy future. The construction of the 200 MW BESS in Twiggs County, along with ongoing projects and future proposals, reflect a broader strategy of integrating renewable energy while addressing the growing energy demands of Georgia's residents. Georgia Power remains dedicated to providing reliable and affordable energy, with a commitment to innovation and efficiency in its operations.
