Tennessee Gas Pipeline Proposes $2.2 Billion Natural Gas Pipeline to Link Growing Rocky Mountains Production with Northeastern Markets

---

Researched by Industrial Info Resources (Sugar Land, Texas)--The Tennessee Gas Pipeline Company (TGP) (Houston, Texas), a wholly owned subsidiary of the El Paso Corporation (NYSE: EP) (Houston, Texas), is proposing another major natural gas pipeline expansion to supply the natural gas markets in the northeastern U.S. The proposed Northeast Passage Project is intended to supply 1.2 billion cubic feet per day (bcf/d) from the growing natural gas production region of the Rocky Mountains to the markets of Pennsylvania, New York and New Jersey.

The proposed pipeline will involve the construction of more than 400 miles of 36-inch-diameter pipes and 66 miles of 24-inch-diameter pipes. The new pipeline will originate at an interconnection at the terminus of the Rockies Express Pipeline in Clarington, Ohio. The Northeast Passage Pipeline will run an easterly course and connect with Transco's pipeline system just downstream of Transco's compressor station 195 near Atglen, Pennsylvania, and then continue in a northeast direction and connect with TGP's existing Line 300 near compressor station 325. Beyond station 325, the new pipeline will make an interconnection with the Iroquois Gas Transmission pipeline system at Pleasant Valley, New York. TGP will also expand along its Line 300 to Mahwah, New Jersey.

To support the new pipeline capacity, TGP plans to construct four compressor stations with a combined total horsepower of approximately 88,000. Two compressor stations will be located in Pennsylvania and one compressor station will be located in West Virginia and Ohio. TGP has not determined whether the compression packages will be turbine-based or electric-drive-based or a combination of the two types.

TGP intends to file with the Federal Energy Regulatory Commission in late 2008. Construction on the Northeast Passage Pipeline project could begin in mid-2010 with a completion and start-up date scheduled for the fourth quarter of 2011.
