Williams and Dominion are joining forces to develop the Keystone Connector pipeline, which would carry up to 1 Bcf/d from the Rockies Express Pipeline (REX) terminus in Ohio to eastern and Mid-Atlantic markets. Under the proposal announced Monday, the sponsors want to place the 240-mile pipeline into service by 2013.

The proposed pipeline would extend from Clarington, OH, to Williams’ Transcontinental Gas Pipe Line (Transco) Station 195 in southeastern Pennsylvania. Williams and Dominion would work with potential shippers to determine the level of interest in the proposal.

“Williams and Dominion are uniquely positioned to offer producers year-round access to growing East Coast markets while providing market area customers increased domestic supply alternatives,” the sponsors said.

Williams, through its Rockies Connector project, and Dominion, through its Keystone project, said they had worked independently over the past two years on proposals to link Rockies and growing Marcellus Shale gas supplies with Northeast markets.

Last year Williams said it wanted to combine the Rockies Connector and its Northeast Connector projects into the Northeast Supply Project, which would move gas from Clarington to various delivery points in Transco’s Zone 6 (see Daily GPI, May 7, 2008). Williams previously held open seasons for the two pipe proposals in 2007.

An open season for Dominion’s original Keystone pipeline was launched last year. The pipe was to transport up to 1 Bcf/d from southwestern Pennsylvania, the heart of the Marcellus Shale, to East Coast markets (see Daily GPI, July 1, 2008). The pipeline would have carried gas to Chester County, PA, for delivery to eastern markets through pipes operated by Dominion, Spectra, Williams and NiSource.

The new Keystone proposal, said the sponsors, would leverage assets across the region and create a “logical” gateway to connect emerging gas supplies with the market.
