Production

  • In 2021, Newfoundland and Labrador generated 41.9 terawatt-hours (TWh) of electricity (Figure 1), which is approximately 7% of total Canadian generation. Newfoundland and Labrador is the fifth largest producer of electricity in Canada and has an estimated generating capacity of 8,682 megawatts (MW).
  • Newfoundland and Labrador generates 97% of its electricity from hydroelectric sources. This includes the 5,428 MW Churchill Falls generating station, which is one of the largest power plants in Canada. Newfoundland and Labrador Hydro owns 65.8% of the project and Hydro-Québec owns the remaining 34.2%. Most of the energy from Churchill Falls is sold to Hydro-Québec under a long-term contract that expires in 2041.
  • Newfoundland and Labrador Hydro’s Lower Churchill project involves construction of two hydro generation facilities: Muskrat Falls (824 MW) and Gull Island (2,250 MW). The Muskrat Falls Generating Station was commissioned in late 2021. The Gull Island project, still in the proposal stage, has not yet been sanctioned for construction.
  • After hydroelectricity, oil is the second largest contributor to Newfoundland and Labrador’s electricity capacity. Although oil accounted for 9% of the province’s electricity capacity, it only made up 2% of the generation mix in 2021. Natural gas and wind power also contribute a small proportion to the generation mix.
  • The 490 MW oil-fired Holyrood Thermal Generating Station was once scheduled for shutdown in 2021 after the completion of Muskrat Falls, but Holyrood is now expected to remain operating until 2030. The generating station now primarily operates as a backup facility, generating electricity only during periods of high demand.Footnote 1
  • Newfoundland and Labrador Hydro is responsible for most power generation in the province. There are also independent power producers of hydroelectricity, cogeneration, wind, and biogas.

Trade and Transportation

  • Newfoundland and Labrador is a significant net exporter of electricity. In 2023, net interprovincial and international electricity outflows accounted for 34.5 TWh.
  • The largest recipient of Newfoundland and Labrador’s electricity is Quebec. Approximately 90% of the power generated at Churchill Falls flows to Quebec and neighbouring markets in Canada and the U.S. through long-term power purchase agreements.
  • Newfoundland and Labrador’s transmission system, until recently, consisted of two large networks: the Island Interconnected System, which was isolated from the rest of North America, and the Labrador Interconnected System, which receives hydro power from the Churchill Falls station and connects to Quebec’s infrastructure. Since 2018, the island of Newfoundland is now connected to the North American power grid through the construction of the Labrador-Island Link and the Maritime Link.
  • Construction on the Labrador-Island Link was completed in late 2017 and commissioned in April 2023.Footnote 2 The project consists of a 1,100 km transmission line that carries electricity from the Muskrat Falls generating facility in Labrador to the island of Newfoundland.
  • The Maritime Link was also completed in late 2017 and the line was in service in January 2018. Two subsea cables connect the island of Newfoundland with Nova Scotia and allow access to the North American bulk electric system. The Maritime Link also allows Nova Scotia to receive 20% of the power originating from Muskrat Falls through a fixed rate 35-year agreement. First power from Muskrat Falls to Nova Scotia began in August 2021.Footnote 3
  • Newfoundland Power, a subsidiary of Fortis Inc., is the primary distributor of electricity in the province, serving more than 275,000 customers. Newfoundland Power operates 11,500 km of distribution lines on the island portion of the province.
  • Newfoundland and Labrador Hydro distributes power to the remaining 38,000 rural customers, across more than 7,500 km of transmission and distribution lines. The Newfoundland and Labrador System Operator is responsible for the provincial electricity system in real-time.
  • There are also isolated systems serving 20 communities along the coast of the province. These isolated systems are primarily supported by diesel generation.
  • Newfoundland and Labrador’s Board of Commissioners of Public Utilities regulates both Newfoundland and Labrador Hydro and Newfoundland Power.
