DETROIT, May 15, 2014 /PRNewswire/ -- DTE Energy's Gas Storage and Pipeline segment has secured long-term gathering commitments with Southwestern Energy Co. and Cabot Oil & Gas Corp. which will significantly expand the Bluestone Pipeline.

"The stronger than expected performance of Marcellus reserves in Susquehanna County continues to drive the need for additional infrastructure," said Richard Redmond, executive vice president, DTE Gathering and Processing. "We are excited to further grow our relationship with Southwestern Energy."

The incremental Bluestone Pipeline capacity is supported by long-term agreements with minimum term commitments ranging from 10 to15 years. Once in-service, the expansion facilities will increase the capacity of the Bluestone Pipeline from 600,000 Dth/day to 975,000 Dth/day, a greater than 60% increase in capacity since the gathering system first came online in late 2012.

The 44.5 mile Bluestone Pipeline and Gathering system can currently transport up to 600,000 Dth/day combined to both the Millennium Pipeline in Broome County, N.Y. and the Tennessee Gas Pipeline in Susquehanna County, Pa.

"We are pleased to have the opportunity to expand our gathering services in Susquehanna County to Cabot Oil & Gas," said Redmond.
