Enbridge Income Fund has a 50% investment in NRGreen which operates four non-regulated waste heat recovery facilities located in Saskatchewan along the Alliance Pipeline.

Electricity is generated by harnessing the waste heat produced by Alliance Canada's gas turbines at its compressor stations and converting it to electrical energy. Each of the four units produce approximately 5 megawatts (MW) of power – enough energy to power the equivalent of approximately 5,000 homes.
