Williams Launches Open Season for Marcellus Pipeline Expansion

A unit of Williams Partners is initiating a binding open season from March 4 to March 26, 2010, for an expansion of its Transco pipeline to provide incremental firm natural gas transportation capacity to transport growing Pennsylvania Marcellus supply to New York and New Jersey markets.

The Northeast Supply Link expansion project is designed to provide 420,000 dekatherms per day of firm service on Williams Partners' Transco natural gas pipeline from interconnections accessing Marcellus production along its Leidy Line in Pennsylvania to its Station 210 pooling point and existing New York City delivery points. Transco has executed a precedent agreement with an anchor shipper for 200,000 dekatherms per day of the capacity and the remaining 220,000 dekatherms per day will be offered to others in the open season.

Williams owns 84 percent of Williams Partners, including the general-partner interest. Most of Williams' interstate gas pipeline and midstream assets are held through its ownership interest in Williams Partners.

"This project is the latest in a long line of expansions of our Leidy Line to provide customers access to abundant supplies closer to our Northeast markets," said Phil Wright, president of Williams' natural gas pipeline business. "And it is yet another example of Williams' expanding role in bringing our nation and our customers clean-burning natural gas from a region right here at home that is now able to employ growing numbers of American workers. We are committed to expanding our Transco system to ensure that customers can take full advantage of this major emerging supply source."
