261 Upgrade Projects


Project Overview

On Oct. 19, 2018, Tennessee Gas Pipeline Company, L.L.C. (TGP), a subsidiary of Kinder Morgan, filed an application with the Federal Energy Regulatory Commission (FERC) for TGP’s 261 Upgrade Projects.

The 261 Upgrade Projects will create 72,400 dekatherms per day (Dth/d) of additional transportation capacity of natural gas on the existing Tennessee Gas Pipeline system. The 261 Upgrade Projects are both located in Agawam, Massachusetts and include the Looping Project and the Horsepower (HP) Replacement Project. The Looping Project involves the installation of 2.1 miles of a 12-inch diameter pipeline loop that will run parallel and adjacent to an existing TGP pipeline. The company will also remove an inactive 6-inch diameter pipeline and replace it with the new 12-inch diameter pipeline loop upgrade in certain locations. The HP Replacement Project involves the replacement of two existing turbine compressor units with one new, cleaner-burning turbine compressor unit, as well as the installation of auxiliary facilities at TGP’s existing Compressor Station 261.

The Looping Project was placed in service in November 2020, and the HP Replacement Project is expected to be placed in service in November 2021.

Project Benefits

The 261 Upgrade Projects will create 72,400 Dth/d of new firm transportation capacity, of which 45,400 Dth/d will be used to provide long-term firm transportation service to the projects shippers, Columbia Gas of Massachusetts and the Holyoke Gas and Electric Department. The remaining 27,000 Dth/d of incremental firm transportation capacity will provide natural gas through TGP’s interconnection with Iroquois Gas Transmission System at Wright, New York to the Compressor Station 261 in Agawam, Massachusetts. This new capacity will help alleviate capacity-constrained New England gas markets, as well as improve the efficiency of and reduce certain emissions by replacing two less efficient, older, existing compressor units at Compressor Station 261 with a more efficient, newer, cleaner-burning, and lower emission compressor unit.
