Background

As of June 2025, the upgrade opportunity is being evaluated for both combined cycle units at the plant by the Georgia Public Service Commission. The scope of this upgrade includes replacing rotating blades and stationary vanes in the combustion turbines, combustor replacement, increasing firing temperature and shaft limits, and additional operating mode flexibility. The result of these replacements will be increased capacity and improved heat rate for some operating modes. This upgrade is projected to achieve an incremental capacity of 194 MW (winter). The units upgrades are expected to be completed with an assumed in-service date of January 1, 2029.[9][10]

Impacts

Potential emissions and details on the project's status and permit applications can be viewed on Oil and Gas Watch page here.

The Oil and Gas Watch database, created by Environmental Integrity Project (EIP), is a free, public-facing tool designed to track the rapid expansion of fossil fuel and petrochemical infrastructure in the United States. Oil and Gas Watch maps new and expanding oil, gas, and petrochemical infrastructure projects across the country and monitors each project’s construction status so the public can stay informed about major oil and gas developments being proposed in their communities. We track key environmental approvals companies must obtain before starting construction or operations and provide access to thousands of government records and permits unearthed by our analysts.
