Production

  • In 2021, NWT generated about 0.71 terawatt-hours (TWh) of electricity (Figure 1), which is approximately 0.1% of total Canadian production. This includes electricity generated by communities and at industrial sites. NWT has an estimated generating capacity of 233 megawatts (MW).
  • In 2021, 47% of NWT’s electricity came from petroleum and 36% came from hydroelectricity.
  • NWT does not have a territorial electricity grid, however, eight communities around the Great Slave Lake use hydroelectricity serviced by two regional grids. Of the remaining 25 communities in NWT, 23 rely on diesel-fired power plants. Norman Wells uses natural gas for electricity generation and Inuvik has both diesel and natural gas facilities.Footnote 1
  • The Northwest Territories Power Corporation (NTPC) generates NWT’s electricity from hydro, fossil fuel, and renewable sources. The major hydro generators include the Snare (30 MW), Bluefish (6.6 MW), and Taltson (18 MW) hydro systems.
  • The Government of NWT is working on the Taltson Hydroelectric Expansion Project with the goal of expanding the capacity of the existing Taltson generating station and connecting the Taltson and Snare hydroelectric systems to improve overall reliability. The expansion would add 60 MW of capacity.
  • Naka Power (formerly Northland Utilities Ltd.) operates diesel generators to provide power to Dory Point-Kakisa, Fort Providence, Sambaa K’e, and Wekweeti.
  • The Inuvik natural gas-fired power plant, which was supplied by the Ikhil gas field from 1999 to 2012, was restarted in January 2014 with LNG imported by truck from Alberta and British Columbia (B.C.). In December 2021, NTPC was approved for a grant to install a third LNG tank at the Inuvik power plant that will allow the community to rely less on its diesel generator for electricity.Footnote 2 NTPC is also evaluating the potential to supply other NWT communities on the road system with LNG to fuel local generators along with diesel.
  • Wind energy provides approximately 4% of NWT’s electricity capacity. In 2012, the Diavik Diamond Mine installed four wind turbines with a capacity of 9.2 MW to provide electricity for its primarily diesel-based microgrid at Lac de Gras.
  • Diavik is also planning to install northern Canada’s largest solar farm. The solar array is expected to provide up to 25% of Diavik’s electricity for operations and for closure work that will run until 2029. Commercial production from the Diavik mine is expected to end in early 2026.Footnote 3
  • The 3.5 MW Inuvik High Point Wind Project was operational in fall 2023. The project included a new transformer and battery storage system. The project is expected to contribute to the NWT’s 25% diesel reduction target for electricity.Footnote 4
  • While solar generated less than 1% of NWT’s electricity needs in 2021, many communities have installed small-scale and utility-scale solar capacity. Some noteworthy installed projects include:
    • A 100 kW solar array in Fort Simpson, the largest solar system in northern Canada at the time, was installed in 2012.
    • Colville Lake has been powered by a solar/battery and diesel hybrid system since 2016. The settlement, located north of the Arctic Circle, previously relied entirely on diesel-fired generation.
    • New solar power facilities were installed in Fort Liard (10 kW) and Wrigley (60 kW) in 2016 and in Aklavik (55 kW) in 2017.
    • A 165 kW ground-mounted plant adjacent to the North Mart store in Inuvik.
    • A 1 MW solar farm in Inuvik on a former industrial site.Footnote 5
  • NWT’s Net Metering Program allows electricity customers to generate their own electricity (up to 15 kW) from renewable energy sources and accumulate energy credits monthly for any excess energy they produce, to be used against those months when their usage exceeds their production.
  • The Government of NWT’s 2030 Energy Strategy is being implemented along with the Climate Change Strategic Framework (CCSF) and the NWT carbon tax. One of the strategic objectives of the 2030 Energy Strategy is to reduce greenhouse gas emissions from electricity generation in diesel-reliant communities by 25%.

Trade and Transportation

  • NTPC distributes electricity to end-use customers in 26 of the 33 communities across 565 km of transmission lines and 375 km of distribution lines.Footnote 6
  • Naka Power also distributes electricity to Yellowknife, N’Dilo, Hay River, Sambaa K’e, Kakisa, Dory Point, Fort Providence, Wekweeti, Enterprise, and K’at’lodeeche.
  • Both NTPC and Naka Power are regulated by the NWT Public Utilities Board.
  • Because of long distances from populated areas to neighbouring provinces and territories, there are no transmission lines to enable the trade of electricity between NWT and other jurisdictions.
  • There are two regional electricity grids in NWT: the North Slave (Snare Grid) and South Slave (Taltson Grid) regions. Both grids are connected to NWT’s hydroelectric supply, but do not connect with each other. Additionally, there are 25 local, independent systems not connected to either regional grid. The Taltson Hydroelectric Expansion Project aims to integrate NWTs’ hydro capacity into one hydro grid.
  • The first phase of the proposed Taltson Hydro Expansion consists of connecting the Snare and Taltson grids. A later phase involves the integration of NWT’s electrical grid with Alberta or Saskatchewan.Footnote 7
