A unit of Williams Partners LP 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% 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.
