T-South Reliability and Expansion Program

Return to project


The program scope involves replacing old compressor station units and adding an additional compressor station unit as well as additional smaller upgrades and reliability enhancements at other locations along the T-South system. Five compressor units and associated equipment to support their operation will be installed at five existing compressor stations. The new compressor units will be quieter and more environmentally friendly than the existing units being replaced. They will make use of noise reduction and low emission technology that meet all environmental and regulatory requirements.

Compressor stations are used to move natural gas through a pipeline to maintain its flow and pressure. Over long distances, friction and geographic elevation differences slow the movement of gas and reduce its pressure. A compressor station gives the natural gas a “boost.” New units will be installed at:

  • Compressor Station 3 near McLeod Lake B.C.
  • Compressor Station 4A near Summit Lake, B.C.
  • Compressor Station 4B near Hixon, B.C.
  • Compressor Station 5 near Kersley, B.C.
  • Compressor Station 6A near 150 Mile House, B.C.
