Compression Facilities

Natural gas is moved through a pipeline under pressure. As natural gas moves through a pipeline it loses pressure due to friction against the inside of the pipe. To keep the natural gas moving at the desired rate, the pressure must be increased. This is accomplished with compressor stations located along a pipeline.

Compressor Stations

Initially, four compressor stations will be built as part of the proposed Mackenzie Gas Project. They will be located near Little Chicago, Norman Wells, Blackwater River and Trail River. Compressor stations also include cooling and/or refrigeration equipment, as needed, to control the temperature of the natural gas.

All facilities will meet applicable Canadian environmental standards, including those for noise.

Trout River Heater Station

As natural gas flows through a pipeline it gets colder. The natural gas must be heated to keep it within the operating temperature range.

A heater station will be located near Trout River, about 95 kilometres north of the Alberta border. The heater will use some of the natural gas flowing through the pipeline to heat the rest of the natural gas.

Construction of the heater station will require clearing approximately 10 acres (four hectares). The station will be located in a fenced area of about three acres (1.2 hectares).

Interconnect Facility

The natural gas pipeline will connect with an existing pipeline system in northwestern Alberta.

An interconnect facility will be installed at the southern end of the Mackenzie natural gas pipeline, in northwestern Alberta. It will have two primary purposes.

  • To measure the amount of natural gas being transferred to another pipeline system custody transfer.


  • To reduce the pressure and possibly increase the temperature of the natural gas in the pipeline.

Joint studies are under way to define the facilities. Facility requirements being studied include:

  • A pig receiver
  • Temperature control
  • Pressure control
  • Metering
  • System isolation

Downstream Connections

When natural gas from the Mackenzie Valley Pipeline joins the Alberta pipeline system, it will connect with a vast system of natural has pipelines built across North America. At the end of these large pipeline systems are smaller local pipelines. Distribution companies use these smaller lines to deliver natural gas to customers. Customers can include residental, commercial and industrial users.
