Columbia Gas Transmission LLC (Columbia Gas) has received US Federal Energy Regulatory Commission (FERC) approval to place into service the Leach XPress Project located in Ohio, Pennsylvania, and West Virginia, USA.

The Leach XPress Project includes new 30- and 36-in. (762- and 914-mm)-diameter high pressure natural gas pipelines, associated compression, and other appurtenant facilities to connect Columbia’s core infrastructure in West Virginia, Pennsylvania, and Ohio with existing third-party gathering pipelines and processing systems in the Majorsville, West Virginia, and Clarington, Ohio, areas. According to FERC documents, the project was supply-driven and designed to expand the capacity of Columbia’s existing pipeline system to transport up to 1,500,000 dekatherms per day.

The project included three new greenfield compressor stations (Lone Oak, Summerfield, and Oak Hill), as well as modifications at two existing compressor stations (Crawford and Ceredo).

Lone Oak Compressor Station (CS) utilizes three new 15,339 hp (11,442 kW) Solar Mars 100 turbine-powered compressors. Summerfield CS utilizes two new 7431 hp (5543 kW) Solar Taurus 60 turbine-powered compressors. Oak Hill CS utilizes three new 15,692 hp (11,706 kW) Solar Mars 100 combustion turbines. Each compressor station is equipped with one new 1175-hp (867-kW) Waukesha engine-powered emergency generator.

Ceredo CS modifications included the addition of three new Siemens electric motor driven Solar Turbine C45 centrifugal compressors with an output of 11,000 hp (820 kW) each.

Crawford CS modifications included piping, valves, and regulators within the existing compressor station to allow for the flow of the proposed quantities of natural gas.
