Tennessee Gas Places 300 Line Into Service

El Paso Corporation’s wholly owned subsidiary, Tennessee Gas Pipeline, has placed its 300 Line Project in service, marking the completion of one of the largest natural gas infrastructure projects currently under way in the Northeast United States.

The upgrade provides access to new and existing natural gas supplies and increases capacity on the TGP system by 350,000 Dth/d. Cost of the project was about $700 million. All the project capacity is contracted under a long-term firm transportation agreement with EQT Energy, LLC.

The 300 Line Project included installation of eight looping segments in Pennsylvania and New Jersey totaling 127 miles of 30-inch pipeline and addition of 55,000 horsepower through the installation of two compressor stations and upgrades at seven existing compressor stations.
The project provides access to diversified natural gas supplies from Gulf Coast, Appalachian, Rockies, and Marcellus shale supply areas, and gas deliveries to points along the 300 Line path and into interconnections with other pipelines in northern New Jersey, as well as an existing delivery point in White Plains, NY.
