Canada still has significant untapped hydro potential, and this article provides insight into eight projects that are being built or are planned for future construction across the country. An impressive number: The work in this article represents more than US$33 billion of investment.

What is the status of hydropower development in Canada? This article will give you insights into work under way at hydro projects either planned or under construction in eight Canadian provinces. In all, this activity could add more than 3,880 MW of clean, renewable hydropower capacity in the country. Even more impressive, the total dollar value of this development work would be well over US$33 billion.
You may notice we haven’t covered every area of the country. In total, Canada is made up of 10 provinces and three territories. However, in five of these, we are not aware of any current significant hydro project development activity: Northwest Territories, Nova Scotia, Nunavut, Prince Edward Island and Yukon. Therefore, these five are not included in this article. If you know of a project we should cover in the future, email firstname.lastname@example.org.
Project Name: Brazeau Hydro Pumped Storage
Location: Brazeau County (southwest of Drayton Valley)
Waterway: Brazeau River
Generating Capacity: Up to 900 MW
Construction Start Date: 2021 (estimated)
Construction Complete Date: 2025 (estimated)
Anticipated Cost: C$1.8 billion to $2.5 billion (US$1.4 billion to $2 billion)
Details: TransAlta is planning to develop a hydro pumped-storage project at its existing hydro facility on the Brazeau Reservoir, southwest of Drayton Valley. The Brazeau Hydro Pumped Storage Project has the potential to provide a capacity of up to 900 MW of renewable energy, close to where the power is needed, while creating economic opportunities for Albertans, TransAlta says. The project would support the transition to generate 30% of Alberta’s electricity from renewable sources by 2030. The proposed project would provide benefits to Alberta’s electricity system, backstopping fluctuations in wind and solar generation. Development work on the Brazeau Hydro Pumped Storage project began in November 2016. For more information, visit brazeauhydro.com.
Project Name: Site C
Developer: BC Hydro
Location: Fort St. John
Waterway: Peace River
Generating Capacity: 1,100 MW
Construction Start Date: Summer 2015
Construction Complete Date: 2024
Anticipated Cost: C$8.8 billion (US$7 billion)
Details: This project, the third dam and hydroelectric generating station on the Peace River, will consist of a 1,050-m-long earthfill dam 60 m high above the riverbed. An 800-meter-long roller-compacted-concrete buttress will be built to enhance seismic protection. The powerhouse will contain six 183-MW turbine-generator units and is expected to produce about 5,100 GWh of electricity annually. Site C will take advantage of water already stored in the Williston Reservoir, generating about 35% of the energy produced at the W.A.C. Bennett powerhouse with only 5% of the reservoir area. The provincial government approved Site C to proceed to construction in December 2014.

Project Name: Keeyask
Developer: Keeyask Hydropower Limited Partnership (Manitoba Hydro, Tataskweyak Cree Nation, War Lake First Nation, York Factory First Nation and Fox Lake Cree Nation)
Location: 725 km northeast of Winnipeg
Waterway: Nelson River
Generating Capacity: 695 MW
Construction Start Date: July 2014
First Unit in Service Date: August 2021
Anticipated Cost: C$8.7 billion (US$7 billion)
Details: The Keeyask Generating Station is under construction 35 km upstream of the existing 1,220-MW Kettle Generating Station. It will involve more than 2 km of dams across Gull Rapids, a seven-bay spillway on the south side of Gull Rapids, and 23 km of dykes built on the north and south side of the reservoir. The reservoir impounded will be about 93 square kilometers and about 40 kilometers long. The powerhouse/service bay complex built across the north side of Gull Rapids will contain seven turbine-generator units. When complete, it will be the province’s fourth largest generating station and is expected to produce 4,400 GWh of electricity annually.

Project Name: Grand Falls Expansion
Developer: NB Power
Location: Grand Falls
Waterway: Saint John River
Generating Capacity: 100 MW
Construction Start Date: Not yet determined
Construction Complete Date: Not yet determined
Details: The latest work on this project was the preparation of a cost estimate to be used in future planning. The estimate was based on an expansion consisting of adding a new 100-MW station beside the existing 66-MW Grand Falls generating station. NB Power carried out preliminary environmental and geotechnical studies and site testing in 2016 in support of the engineering estimate. The project would require construction of a new intake structure and powerhouse, including a second tunnel. The information obtained from this exercise will be used for future planning by NB Power. This unit would help NB Power meet its long-term clean energy requirements: 40% of the utility’s in-province electricity sales must come from renewable sources by 2020.

Newfoundland and Labrador
Project Name: Muskrat Falls
Developer: Nalcor Energy
Waterway: Churchill River
Generating Capacity: 824 MW
Construction Start Date: 2013
Construction Complete Date: End of 2019 (first power) and fall 2020 (full power)
Anticipated Cost: C$10.1 billion (US$7.9 billion), which includes C$5.5 billion for generation assets and C$4.6 billion for transmission assets
Details: The Muskrat Falls hydroelectric generation facility is being built downstream from the existing Churchill Falls plant and is one component of the lower Churchill River complex that could eventually include the 2,250-MW Gull Island plant. The facility consists of a spillway, two dams and a powerhouse containing four turbine-generator units. Once constructed, it will be the second largest hydroelectric facility in the province.

Each station has an associated rockfill dam, two generating units, and a spillway. Each generating station is linked to the regional highway via a permanent access road 150 km long. The 640-MW Romaine-2 station was completed in 2014, 270-MW Romaine-1 was completed in 2015, and 395-MW Romaine-3 was completed in 2017. The 245-MW Romaine-4 facility is under construction.

Project Name: Saskatoon Weir Run-of-River Hydropower Project
Developer: Saskatoon Light & Power, a division of the City of Saskatoon
Waterway: South Saskatchewan River
Generating Capacity: 6.1 MW
Construction Start Date: 2020
Construction Complete Date: 2022
Anticipated Cost: C$65 million (US$50.6 million)
Details: This hydro project would be built at the existing Saskatoon Weir on the South Saskatchewan River. This weir was completed in 1940 and is an 11-foot-high concrete ogee-crested structure about 985 feet long. The existing weir infrastructure would be renewed and the hydropower station would be built on the university side of the river (river right). The city expects project funding to come from the Saskatoon Tribal Council and private partners, offset from revenue generated by the power station and funding from other levels of government.
