El Paso Corporation has announced that Tennessee Gas Pipeline (TGP), a wholly-owned subsidiary, has entered into 20-year contracts with Chesapeake Energy Marketing, Inc., and StatOil Natural Gas LLC, for all of its Northeast Upgrade Project capacity - i.e., 636,000 Dth/day from TGP's 300 Line in Pennsylvania to an interconnect in New Jersey. "The Northeast Upgrade Project is a natural extension of TGP's presence in the heart of the developing Marcellus Shale play. The project would cost approximately $400 million with a majority of the capital spending taking place during 2013."
