Iroquois Gas Transmission System, L.P. (Iroquois) is seeking US Federal Energy Regulatory Commission (FERC) approval to construct, own, operate, and maintain new natural gas compression and associated facilities at four existing compressor stations in New York and Connecticut, USA, as part of its Expansion By Compression Project.

Iroquois proposes to add 12,000 horsepower (8952 kW) of new compression and associated facilities at its Athens Station in Greene County, and Dover Station in Dutches County, New York. Iroquois proposes to add two new 12,000 hp units at its Brookfield Station in Fairfield County, Connecticut, for a grand total of 48,000 hp (35,808 kW) of new compression facilities. Iroquois proposes to add cooling and related equipment only at its Milford Station in New Haven County, Connecticut. The purpose of this project is to provide a total of 125,000 dekatherms per day of incremental firm transportation service to existing customers.

Specific project details include:

Athens Compressor Station

Iroquois will add one new 12,000 hp Solar Taurus 70 compressor to run in addition to the already existing 10,310 hp (7691 kW) Solar Taurus 70 compressor on site. It will also construct an on skid turbine compressor enclosure installed in an acoustically designed compressor building, a low noise turbine exhaust system which includes oxidation catalyst housing, a low noise turbine air inlet system, a low noise turbine lube oil cooler, a gas cooler, and above-ground and below-grade gas piping.

Dover Compressor Station

The Dover Compressor Station consists of one 17,969 hp (13,405 kW) Siemens Cyclone, with Iroquois proposing to add one 12,000 hp Solar Taurus 70 compressor, an on skid turbine compressor enclosure installed in an acoustically designed compressor building, a low noise turbine exhaust system including oxidation catalyst housing, a low noise turbine air inlet system, a low noise turbine lube oil cooler, a station gas cooler, and aboveground and below grade gas piping.

Brookfield Compressor Station

Iroquois will add two 12,000 hp Solar Taurus 70 compressors to run in addition to the station’s already existing Solar Taurus 60 (7,684 hp [5732 kW]), and Solar Taurus 70 (10,310 hp) compressors. It will also construct a new control/office building, exhaust systems, air inlet systems, lube oil coolers, low noise gas coolers, and piping.

Milford Compressor Station

Iroquois will install new gas cooling equipment to the two existing 10,310 hp Solar Taurus 70 compressor units in the station. It will also build associated piping to allow for compressed discharge gas to be cooled, as no gas cooling facilities currently exist at the Milford compressor station. No new compression will be added.
