Project details

• Operator: Texas Eastern Transmission LP
• Owner: Enbridge
• Parent company: Enbridge
• Capacity: 11,690 Million cubic feet per day
• Length: 8825 mi
• Status: Operating
• Start year: 1942

Background

Texas Eastern Transmission (TETCO) is operated by Texas Eastern Transmission, LP, which is owned by Enbridge.

Spectra Energy and Conocophillips have proposed a joint expansion project called the TEMAX Project that would add 33 miles of pipeline to the system, stretching from Clarington, Ohio to Delta, Pennsylvania. It would add 395 million cubic feet per day of capacity and cost $500 million. The project includes construction of pipeline, looping and replacement of compressor stations and is is preparing to pre-file with FERC.

In January of 2019 an explosion in the pipeline injured two people and destroyed two homes in Noble County, Ohio.

Expansion projects

TEMAX Pipeline Expansion

In 2008, Spectra and ConocoPhillips announced a proposed pipeline called the TEMAX Pipeline. Gas would run through the TETCO Pipeline system, forming an agreement to deliver up to 395 million cubic feet per day of Rocky Mountain natural gas to the U.S. Northeast through the planned pipeline expansion. The expansion will start in Clarington, Ohio, running through Spectra’s Texas Eastern Transmission pipeline system to Delta, Pennsylvania.

There have been no development updates since 2008 and the project is presumed to be cancelled.

Texas Eastern Appalachia to Market (TEAM)

The pipeline project includes the installation of new pipeline and upgrading of existing pipeline and compressors along the TETCO system. There have been multiple TEAM expansions.

In October 2008, TETCO held an open season for the TEAM expansion project. In September 2011, FERC published the environmental assessment of Texas Eastern Appalachia to Market 2012 Expansion Project. The project involved installation of 17.3 miles of 36-inch-diameter natural gas transmission pipeline in Greene, Fayette, Franklin, Adams and Fulton Counties, Pennsylvania. TETCO also proposed to abandon approximately 11.3 miles of 24-inch-diameter pipeline in Franklin and Adams Counties, Pennsylvania. In October 2012, TETCO completed the expansion.

• Operator: TETCO
• Current capacity: 200 Mmcf/d
• Length: 17.3 miles / 28 km
• Diameter: 36 inches
• Status: Operating
• Start Year: 2012
• Cost: US $197 million

In November 2014, TETCO completed TETCO TEAM 2014 expansion. TEAM 2014 involved construction of approximately 33.4 miles of 36-inch-diameter natural gas transmission pipeline comprised of seven separate pipeline loops in Pennsylvania, and modification of existing pipeline facilities in Pennsylvania, West Virginia, Ohio, Kentucky, Tennessee, Alabama, and Mississippi.

In December 2011, Chesapeake Energy, American Electric Power and Spectra Energy Corp announced a pipeline expansion of the Texas Eastern system, connecting Utica and Marcellus shale in Ohio to markets in East and South. U.S. Federal Energy Regulatory Commission approved the project on 02 December, 2014. Ohio Pipeline Energy Network project was originally scheduled to become operational in November 2015, but the mainline portion of the project, which is the reverse flow along part of the existing TETCO mainline began service in mid-September.

Texas Eastern Appalachian Lease (TEAL) Gas Pipeline

The extension would begin near the village of Bern, Ohio and turn north at Clarington, Ohio.
