Southern Star Advances Kansas Gas Pipeline Project as FERC Opens Review
FERC has launched environmental review of Southern Star’s proposed Viola Project in Kansas, which includes a 19-mile natural gas pipeline and compressor station to supply a new 710-MW power plant.
(P&GJ) — The Federal Energy Regulatory Commission (FERC) has begun the environmental review process for Southern Star Central Gas Pipeline’s proposed Viola Project in Sumner County, Kansas, which would include a new pipeline and compressor station designed to support a planned gas-fired power plant.
According to the notice, FERC staff will prepare an environmental document evaluating the potential impacts of the project before deciding whether it meets the requirements for a Certificate of Public Convenience and Necessity.
Southern Star proposes constructing approximately 19.33 miles of new 16-inch-diameter pipeline, known as Line UA, which would connect to the company’s existing 20-inch Line U system. The project also includes a new compressor facility and related infrastructure.
The planned Wellington Compressor Station would include three compressor units totaling 12,375 horsepower, along with supporting equipment and a new mainline valve. A new meter station would connect the pipeline to the 710-MW Viola combined-cycle power plant, which is being developed by Evergy Kansas Central.
Once completed, the pipeline and compressor facilities would be capable of transporting up to 116,296 dekatherms per day of natural gas to the power generation facility.
Construction of the project would disturb approximately 266 acres of land, with about 164 acres remaining in use for long-term operation after restoration activities are completed.
FERC has opened a public scoping period to gather input on environmental issues related to the project as part of its review under the National Environmental Policy Act (NEPA). The agency is requesting comments from the public and other stakeholders before 5:00 p.m. ET on April 3, 2026, which will help determine the scope of the environmental analysis.
