NTPC was formed in 1988 to acquire and operate the former assets of the Northern Canada Power Commission in the Northwest Territories, including what is now Nunavut.
Since 2007, NTPC is organized as a subsidiary of the Northwest Territories Hydro Corporation.
This has led NTPC to be recognized as a Gold Champion Level Reporter by the Canadian voluntary Challenge and Registry for seven consecutive years, including a leadership award and an honourable mention.
Liquid natural gas and diesel are used to generate electricity in Inuvik.
All other communities served by NTPC generate power using diesel.
