Gulf Xpress Project Gets FERC Environmental Approval

Columbia Gulf Transmission LLC has received a favorable Environmental Impact Statement (EIS) from the US Federal Energy Regulatory Commission (FERC) for its Gulf Xpress project (GXP), paving the way for FERC to approve or not approve the project.

Columbia Gulf requested authorization to construct and operate seven new compressor stations and to upgrade one compressor station and one existing meter station in Kentucky, Tennessee, and Mississippi, USA. If approved, the GXP would provide about 860,000 dekatherms per day of natural gas delivery to markets in the US Gulf Coast region.

Morehead Compressor Station: This new 44,800-hp (33,420-kW) station would be constructed in Rowan County, Kentucky. The Morehead Compressor Station would include two Solar Turbines Titan 130E turbine-driven compressors, filter/separators, gas cooling bays, and suction and discharge piping. The station would have bidirectional capabilities to compress gas north or south on Columbia Gulf’s existing Mainline 200 and 300, and flow gas into the existing Mainline 100.

Paint Lick Compressor Station: This new 41,000-hp (30,586-kW) station would be constructed in Garrard County, Kentucky. The Paint Lick Compressor Station would include two Solar Turbines Titan 130 natural turbine-driven compressors, filter/separators, gas cooling bays, and suction and discharge piping. The station would have bidirectional capabilities to compress gas north and south on Lines 200 and 300 and flow gas into Line 100.

Goodluck Compressor Station: This new 31,800-hp (23,722-kW) compressor station would be constructed in Metcalfe County, Kentucky. The Goodluck Compressor Station would include two Solar Turbines Mars 100 turbine-driven compressors filter/separators, gas cooling bays, and suction and discharge piping.

Cane Ridge Compressor Station: This new 41,000-hp compressor station would be constructed in Davidson County, Tennessee. The Cane Ridge Compressor Station would include two Solar Turbines Titan 130 natural turbine-driven compressors, filter/separators, gas cooling bays, and suction and discharge piping.

Clifton Junction Compressor Station: This new 31,800-hp station would be constructed in Wayne County, Tennessee. The Clifton Junction Compressor Station would include two Solar Turbines Mars 100 turbine-driven compressors, filter/separators, gas cooling bays, and suction and discharge piping.

New Albany Compressor Station: This new 31,800-hp station would be constructed in Union County, Mississippi. The New Albany Compressor Station would include two Solar Turbines Mars 100 turbine-driven compressors, filter/separators, gas cooling bays, and suction and discharge piping.

Holcomb Compressor Station: This new 31,800-hp station would be constructed in Grenada County, Mississippi. The Holcomb Compressor Station would include two Solar Turbines Mars 100 turbine-driven compressors, filter/separators, gas cooling bays, and suction and discharge piping.

Grayson Compressor Station: Columbia Gulf proposes to add a 15,900-hp (11,861-kW) compressor to the recently approved 36,400-hp (27,154 kW) Grayson Compressor Station in Carter County, Kentucky. The upgrade would include one Solar Turbines Mars 100 turbine-driven compressor and associated piping within the existing compressor building.

Editor’s note: Receiving the EIS is the final step before FERC decides whether to approve the project or not. As of press time, FERC lacks the quorum necessary to approve projects, which means these projects will not be up for approval until new members join the regulatory body.
