Nrgreen power
Encyclopedia
NRGreen Power Limited Partnership (“NRGreen”) is involved in the commercial development of electrical generation opportunities associated with the Canadian portion of the Alliance Pipeline natural gas system by recovering and converting waste heat at compressor stations and generating it into electricity.
Under a long-term (20-year) power agreement with SaskPower, NRGreen Power has constructed four waste heat power generation units at Kerrobert, Loreburn, Estlin, and Alamedain, all in Saskatchewan. Each of the four units produce approximately 5 megawatts of power – enough energy to power the equivalent of approximately 5,000 homes.
NRGreen Power will be adding a fifth waste heat recovery unit to be built at Alliance’s Windfall compressor station near Whitecourt, Alberta. The Whitecourt Recovered Energy Project ("WREP") will employ General Electric’s ORegenTM power system to generate 14 MW of electricity per hour, with no new emissions or water use.
As this heat would otherwise be released directly into the atmosphere, this method of power generation is environmentally responsible because electricity can be produced without creating any new greenhouse gases or other emissions. Each NRGreen waste heat power generation unit is designed to produce 5 megawatts of power – enough energy to power the equivalent of approximately 5,000 homes.

Overview
Utilizing technologies developed and manufactured by Ormat and GE, the waste heat units constructed at Alliance Pipeline’s four compressor stations in Saskatchewan, and The Whitecourt Recovered Energy Project (“WREP”),recover the exhaust heat from natural gas turbines (which compress the gas to transport it through the pipeline) and convert it into electricity.Components
Each waste heat power generation unit has three main components: a heat exchanger, a thermal oil loop and an energy converter. A unique feature of the waste heat power generation system is that it is entirely self-contained. Electricity leaves the station via transmission lines (owned by the transmission facilities owner) and goes to the power company’s grid for distribution to customers.As this heat would otherwise be released directly into the atmosphere, this method of power generation is environmentally responsible because electricity can be produced without creating any new greenhouse gases or other emissions. Each NRGreen waste heat power generation unit is designed to produce 5 megawatts of power – enough energy to power the equivalent of approximately 5,000 homes.
