Iroquois Gas Transmission System (Iroquois) has filed a petition requesting the reissuance of US Federal Energy Regulatory Commission (FERC) approval for the construction and operation of its previously authorized Wright Interconnect Project (WIP). The company states that the scope and design of the project remain unchanged from the original approval issued in 2013.
Under the request, Iroquois seeks renewed certificate authority to construct a new receipt-point interconnection with Constitution Pipeline Company (Constitution); build a new 21,800‑hp (16,262‑kW) transfer compressor station (the Constitution Compressor Station); modify the existing Wright Compressor Station; upgrade metering facilities; and install related appurtenances. All facilities will be located in Schoharie County, New York.
Once completed, the WIP facilities would enable a new interconnection between Iroquois and Constitution while adding 650,000 dekatherms per day of predominantly firm transportation capacity from the new receipt point to both Iroquois’ existing mainline system and the Tennessee interstate pipeline system located in Wright, New York.
The Constitution Compressor Station will house two 10,900‑hp (8131‑kW) turbo compressors. Currently, Iroquois operates two 7200‑hp mainline compressor units and associated natural gas cooling equipment at the Wright Compressor Station. These compressors support the movement of natural gas for firm customers from Iroquois’ interconnect with TransCanada at Waddington, New York, to delivery points in Iroquois Zone 2 downstream of the station. The maximum allowable operating pressure of the Iroquois system near the Wright Compressor Station is 1,440 psi (99 bar).
To accommodate natural gas deliveries from Constitution and support the proposed firm transmission capacity, the Constitution Compressor Station will be constructed adjacent to the existing Wright Compressor Station. The additional compression capability will increase the pressure of gas delivered by Constitution, enabling it to enter and flow efficiently through Iroquois’ system.
