Dominion Transmission Inc. (DTI) has received authorization to construct and operate its New Market Project which will provide 112 MMcf/d (3 x 106 m3/d) of capacity to serve markets in the US Northeast and Mid-Atlantic regions. Nearly 33,000 hp (24,608 kW) of compression will be added to DTI’s existing interstate pipeline transmission system.
Dominion will construct and operate two new compressor stations and upgrade and modify three existing compressor stations and one meter and regulating (M&R) station in New York. Specifically, Dominion proposes to construct and operate: (1) a new 11,010 hp (8210 kW) compressor station, consisting of one natural gas-fired turbine compressor and associated equipment, and 1425 ft. (434 m) of 42-in. (1066 mm) diameter pipeline in Chemung County (Horseheads Compressor Station); (2) a new 10,880 hp (8113 kW) compressor station, consisting of one natural gas-fired turbine compressor and associated equipment in Madison County (Sheds Compressor Station); (3) a 6393 hp (4767 kW) natural gas fired-turbine compressor, two 2370 hp (1767 kW) reciprocating compressors, and associated equipment, as well as a new M&R facility and station cooler, at the existing Brookman Corners Compressor Station in Montgomery County; (4) a station cooler and modifications to the piping at the existing Borger Compressor Station in Tompkins County; and (5) a station cooler at the existing Utica Compressor Station in Herkimer County. Dominion also proposes to modify its existing facilities at the West Schenectady M&R station in Schenectady County.
