FERC has approved mostly compression expansions for Dominion Transmission Inc. (DTI) in western Pennsylvania and for Tennessee Gas Pipeline in western Massachusetts.

DTI proposes to install an additional 32,440 hp of additional compression at its existing Punxsutawney, Ardell and Finnefrock compressor stations in the western Pennsylvania counties of Jefferson, Indiana, Elk and Clinton to provide 200,000 Dth/d to CONSOL Gas Co., which represents all of the capacity to be created by the project [CP11-39].

DTI said the project will provide additional firm transportation from multiple receipt points along its LN-280 pipelines to an existing interconnection with Transcontinental Gas Pipeline at Leidy, PA. It will give Pennsylvania producers greater access to major natural gas markets in the Northeast and Mid-Atlantic regions, according to DTI, a subsidiary of Richmond, VA-based Dominion.

The Federal Energy Regulatory Commission has (FERC) given DTI one year to complete the $97 million project.

In a separate order, FERC issued Tennessee a certificate to construct a 2,000 hp compressor expansion along its Northampton Lateral on its 200 Line system in western Massachusetts in order to provide incremental firm transportation service for Bay State Gas Co. and The Berkshire Gas Co. [CP11-36].

Tennessee said it has entered into binding precedent agreements with Bay State and Berkshire for a combined total of 10,400 Dth/d of firm transportation service (6,100 Dth/d for Bay State and 4,300 Dth/d for Berkshire) for a primary term of 20 years.

According to Tennessee, it will provide service for Berkshire from an interconnection with Iroquois Gas Transmission System L.P. near Wright, NY, to the Greenfield meter station near Northampton, MA; and will provide firm transportation service for Bay State from an interconnection with Maritimes and Northeast Pipeline LLC located near Dracut, MA, to the Granite Northampton Massachusetts Meter Station near Northampton.

The project calls for Tennessee to construct a new 2,000 hp compressor station and associated facilities on its Northampton Lateral Line 260A-100 in Southwick, MA, to provide an additional 8,305 Dth/d of firm service. When combined with 2,095 Dth/d of turnback capacity reserved for the Northampton Expansion Project, Tennessee will be able to provide the 10,400 Dth/d of firm service requested by the shippers.

FERC has given Tennessee one year to complete the $16.7 million project.
