The Northwest Territories Power Corporation (NTPC) was established about 1988 to acquire and operate the former Northern Canada Power Commission (NCPC) assets within the Northwest Territories, which at that time also included Nunavut.
76% of NTPC's electrical generation is in the form of Hydro electricity. Hydro production has increased approximately 15% since 1990/91, reducing demand on diesel production and lower GHG emissions by 58% of 1990/91 levels. This has led NTPC to be recognized as a Gold Champion Level Reporter by the Canadian voluntary Challenge and Registry for seven cosecutive years, including a leadership award and an honourable mention.
NTPC also vends electricity to Northland Utilities (Yellowknife) Limited, a private company providing electricity in Yellowknife, and to the similarly named Northland Utilities (NWT) Limited in other communities. Natural gas is used to generate electricity in Inuvik and Norman Wells.
