Williams Pipeline recently announced the development of an expansion project, including in the Coosa County area, named the Southeast Supply Enhancement.
Williams owns and operates a natural gas transmission pipeline known as the Transcontinental Gas Pipe Line Company LLC., or Transco. This pipeline transports natural gas from production areas to customers, such as utility companies and power plants, located throughout the northeastern and southeastern United States.
The proposed project is an expansion of the existing Transco pipeline’s capacity in the southeastern U.S. The SSE project would include pipeline looping adjacent to the existing Transco corridor and modifications to eight facilities.
One of the stations for Williams is located within Coosa County. Williams is now in the preliminary stages of developing the Southeast Supply Enhancement Project, which would include compressor station reversal and modifications in Coosa County at Station 105.
The project is being designed to add 1,587,000 dekatherms per day of additional natural gas transportation capacity and is targeted to be in service in the fourth quarter of 2027. Williams states that is enough natural gas to meet the needs of 8.6 million homes.
Coosa County’s station modifications are the only one included in Alabama for the scope of work being done.
The preliminary project scope also includes looping pipeline projects in Virginia and North Carolina, a compressor station reversal in South Carolina and compressor station reversals and regulators in Georgia. Ultimately the expansion is expected to provide natural gas deliveries to all five of those states, including Alabama.
However, before Williams can expand or modify its facilities, the company must first apply for, and obtain, a Certificate of Public Convenience and Necessity from the Federal Energy Regulatory Commission, or FERC. According to recent reports from Williams, the details of the pipeline project proposal have not yet been finalized, and a formal application has not yet been filed with FERC.
However, the company has initiated an environmental pre-filing review of the project with FERC. This review is one of the first steps in the information gathering process and will help the company determine the location of the proposed pipeline facilities that would result in the least impact to the environment and communities.
Information on the review process and the enhancement project may be reviewed on FERC’s website at ferc.gov under docket number PF24-2-000, or by email at customer@ferc.gov.
Williams has stated that it anticipates filing a formal application with FERC in the third quarter of this year. With the project being in such early stages, there is currently no timeline for when the modification work would begin at the Coosa County compressor station, although the target construction start is for the spring of 2026.
