Transmission

Industry Brief

Iroquois Gas Transmission System said it will pursue development of the Wright Interconnect Project (WIP), an expansion of its existing compression and metering facilities in Wright, NY. Last week Constitution Pipeline Co. said that a finalized route it will propose for a Marcellus pipeline included an agreement with Iroquois to expand the compressor station, which would eliminate the need for Constitution to build a 32,0000-hp compressor facility in Schoharie County, NY (see Shale Daily, Jan. 22). The WIP project will enable delivery of up to 650,000 Dth/d of natural gas from the terminus of the proposed Constitution Pipeline in Schoharie County into both Iroquois and the Tennessee Gas Pipeline under a 15 year capacity lease agreement with Constitution, Iroquois said. WIP is targeted for an in-service date of March 2015 to coincide with the startup of the Constitution Pipeline.
