TransCanada Corp. announced its Leach XPress (LXP) Project was placed in-service on January 1, 2018, and that the Federal Energy Regulatory Commission (FERC) has issued a certificate of public convenience and necessity for its Mountaineer XPress (MXP) and Gulf XPress (GXP) projects on December 29, 2017. All three projects provide vital links between Appalachian natural gas supply and growing U.S. markets.
LXP comprises 160 miles of 36-inch pipeline, three compressor stations and modifications to an existing compressor station. Representing an investment of $1.6 billion, the pipeline is capable of transporting 1.5 Bcf/d of natural gas. Via an existing interconnect with TransCanada’s Columbia Gulf Transmission System and its Rayne XPress (RXP) Project which was placed into service last November, LXP will facilitate the delivery of up to an additional 1 Bcf/d to Southeast and Gulf Coast supply markets.
FERC’s thorough review and approval of MXP and GXP follows three years of planning by TransCanada’s project teams, along with over two years of outreach to communities and landowners along the projects’ routes. Once remaining regulatory approvals are obtained, TransCanada plans to begin right-of-way preparation and construction activities on both projects, with an anticipated in-service date in late 2018.
The MXP and GXP projects consist of a combined infrastructure investment of $3.2 billion. MXP will deliver 2.6 Bcf/d of gas to the TCO Pool and Leach markets on the Columbia Gas Transmission System through the construction of 170 miles of 36-inch pipeline, three new compressor stations and upgrades to three existing compressor stations. GXP will transport 0.8 Bcf/d to Southeast and Gulf Coast supply markets through the construction of seven new compressor stations, and upgrades to one existing compressor station, along TransCanada’s existing Columbia Gulf System.
MXP and GXP are expected to create over 8,000 jobs during peak construction later this year. Both are underpinned by long-term, fixed-fee, firm transportation service agreements. They will be designed, constructed and operated with a core focus on safety and minimizing environmental impact.
