Turbine-Powered Compression For Empire North Project

Empire Pipeline Inc. has filed an application with the US Federal Energy Regulatory Commission (FERC) to construct a new 21,068 hp (15,716 kW) compressor station in Tioga County, Pennsylvania, USA, and construct a new 32,000 hp (23,872 kW) compressor station in Ontario County, New York, USA, as part of its Empire North Project.

The Project will create 205,000 dekatherms per day of incremental firm transportation capacity of regionally produced natural gas into the interstate pipeline system, by way of existing Empire pipeline facilities, including local gas distribution markets and market centers in the northeastern United States, such as the State of New York, and Canada.

Of the incremental project capacity, 35,000 dekatherms per day has been subscribed by a New York based local distribution company and 5000 dekatherms per day has been subscribed by an energy marketing company, which serves New York residential, commercial, and industrial end-users. Additionally, 31,000 dekatherms per day of incremental project volumes will have a primary delivery point in upstate New York – namely Empire’s existing interconnection with Tennessee Gas Pipeline Company in Ontario County, New York (Hopewell Interconnection). The remaining incremental project volumes will have a primary delivery point at Empire’s existing interconnection with TransCanada Pipelines Limited in Erie County, New York (Chippawa Interconnection).

Empire proposes to construct and operate two compressor facilities.

Jackson Compressor Station (Jackson CS) will be a 21,068 hp compressor station in Jackson Township, Tioga County, Pennsylvania, USA. The installation of two Solar Taurus 70 natural gas fired, turbine-driven centrifugal compressors rated at 10,534 hp each (7858 kW) will permit Empire to increase the pressure of its pipeline system to 1440 psig (99 bar) immediately downstream of the nexus of the eastern end of Empire’s existing Tuscarora Lateral Pipeline, the southern end of its existing Tioga County Extension Pipeline, and two existing producer interconnection stations, which will in turn allow Empire to transport an additional 205,000 dekatherms per day of natural gas northward on its pipeline system. The new Jackson CS will be supported by a remotely monitored control system, auxiliary air and emergency power systems, and a fully automated emergency shutdown system. The Jackson CS will also be equipped with a vent gas recovery system.

The Farmington Compressor Station (Farmington CS) will be a 32,000 hp compressor station in the Town of Farmington, Ontario County, New York. The installation of two new electric motor-driven compressors at Farmington CS will allow Empire to re-pressurize the Empire Connector Pipeline (ECP) north of the Hopewell Interconnection. This new compression will increase the pressure of the ECP to approximately 1440 psig on the discharge side of the Farmington CS, which will allow Empire to deliver the remaining 174,000 dekatherms per day of incremental Project volumes to the Chippawa Interconnection.
