Transcontinental Gas Pipe Line Co. LLC (Transco) has filed an application with the US Federal Energy Regulatory Commission to construct, own, operate, and maintain its Southeast Supply Enhancement Project.
The project is an expansion of Transco’s existing natural gas transmission system that will enable Transco to provide 1,596,900 dekatherms per day of incremental firm transportation capacity in the southeast United States. This expansion will provide natural gas deliveries to Virginia, the Carolinas, Georgia, and Alabama to meet the growing residential, commercial, and industrial demand in cities across the Mid-Atlantic and Southeast.
Planned compression includes four compressor stations.
Two 33,000 hp electric motor-driven compressor units will be added at Transco’s existing Compressor Station 165 located in Pittsylvania County, Virginia. Compressor Station 165 will be limited to a total incremental output of 45,000 hp, thereby increasing the total certificated station horsepower from 51,930 to 96,930 hp.
Transco will add one 23,465 hp Solar Titan 130 Turbine and two 31,871 hp Solar Titan 250 Turbine driven compressor units at its existing Compressor Station 155 in Davidson County, North Carolina. Compressor Station 155 will have a total incremental 87,207 hp, thereby increasing the total certificated station horsepower from 23,502 to 110,709 hp.
One 15,900 hp Solar Mars 100 Turbine driven compressor will be added at Transco’s existing Compressor Station 150 in Iredell County, North Carolina. Compressor Station 150 will have a total incremental 15,900 hp, thereby increasing the total certificated station horsepower from 61,930 to 77,830 hp.
Transco will add three 33,000 hp electric motor-drive compressor units at its existing Compressor Station 145 in Cleveland County, North Carolina, to provide the incremental horsepower required by the project and accommodate the abandonment (in place) of three 12,500 hp existing electric motor-drive compressors. Compressor Station 145 will have a total incremental 61,500 hp, thereby increasing the total certificated station horsepower from 37,500 to 99,000 hp.
