Waste Heat

Background Information

Recovering waste heat and generating electricity from the hot exhaust gas of gas turbines located at pipeline compressor stations are seen as a way to promote increased energy efficiency and reduce green house gas emissions.  Pipeline companies with facilities in the United States, in concert with the Interstate Natural Gas Association of America (INGAA), have considered ways of expediting the development process for compressor waste heat recovery projects.  As a result of those considerations, a number of pipeline companies have agreed to identify, on a voluntary basis, gas turbine compressor stations on their systems that:

  • Have a total gas turbine station capacity of at least 15,000 hp; and
  • Operated at or more than 5,250 hours per year over the previous 12 months.

Gas Turbine Compressor Stations

The following Gas Transmission Northwest gas turbine compressor stations meet the dual requirements of having a total gas turbine capacity of at least 15,000 hp and operating 5,250 hours or more per year based upon the previous years operational data:

TransCanada Gas Transmission Northwest System

Station 4 - Sandpoint, Idaho
Station 6 – Rosalia, Washington
Station 8 – Wallula, Washington
Station 12 – Bend, Oregon
