CenterPoint Energy Gas Transmission and Duke Energy Gas Transmission Propose Major Pipeline to Link Onshore Supplies to Premium Eastern Markets

Original Mid-Continent Crossing proposal revised and expanded

HOUSTON   -- CenterPoint Energy Gas Transmission Company (CEGT) and Duke Energy Gas Transmission (DEGT) today signed a Memorandum of Understanding to develop a pipeline, the Mid-Continent Crossing (MCX).  The proposed pipeline will stretch from the Waha market center in West Texas, to Oakford/Delmont, Pa, and will offer Midwest and eastern markets access to abundant supplies of natural gas located in the producing basins of the Mid-Continent, Rockies and West Texas. 

CEGT’s initial open season for MCX was to solicit interest in a pipeline originating in Dumas, Texas and terminating in Barton, Alabama.  Initial interest in the project determined that there may be demand to extend this proposed new pipeline from the Southwest and Mid-Continent regions to market centers in the Northeast.

As a result, the scope of CEGT’s original pipeline project has changed. CEGT and DEGT will conduct a new 60-day open season to solicit interest from producers seeking to deliver to premium markets farther north, as well as end-use markets looking to diversify their supply portfolios to include a greater share from western basins.

The proposed expanded pipeline will begin in the Waha market center of West Texas and terminate near Oakford/Delmont.  The approximately 1,600-mile, 42 - and 36-inch pipeline would have the capacity of between 1.50 and 1.75 billion cubic feet per day and will connect significant onshore gas supplies with key downstream markets. The pipeline could be in service as early as the fourth quarter of 2008.  Producing basins that will benefit from this market access include the Rockies, San Juan, Permian, Delaware, Granite Wash, Raton, Palo Duro, Anadarko, Arkoma and Fayetteville Shale. 

“We are pleased to work with DEGT on another project of this magnitude,” said Byron Kelley, president of CenterPoint Energy’s pipeline group.  “Following both companies’ existing rights-of-way for the majority of the route will enable us to build quickly and at a lower cost than other alternatives.  The new pipeline will provide market access for producers and bring needed supplies to key gas-consuming markets.”                    

“This new pipeline system will provide customers in energy-hungry markets in the East with a competitive supply alternative for accessing growing, reliable onshore supply sources,” said Martha Wrysch, president, DEGT. “We are excited about our partnership with CenterPoint Energy to connect Mid-Continent producers with customers looking to access diverse supply sources.”

The non-binding open season will run from June 1 – July 31.
