Robert-Bourassa Dam Canada
The Robert-Bourassa Dam is a hydroelectric dam located on the La Grande River in northern Quebec, Canada. It is the largest hydroelectric facility in the province and the third largest in Canada. The dam is named after Robert Bourassa, a former premier of Quebec who oversaw the James Bay hydroelectric project of which the dam is a part.
Construction on the dam began in 1974 and was completed in 1981. It has a height of 162 meters (531 feet) and a length of 2,835 meters (9,301 feet). The reservoir created by the dam, known as the Robert-Bourassa Reservoir, has a surface area of over 2,800 square kilometers (1,080 square miles) and can store up to 61 billion cubic meters (49 million acre-feet) of water.
The dam has 16 generating units, each with a capacity of 768 megawatts, for a total capacity of 12,288 megawatts. It provides electricity to Quebec and also exports power to the United States.
The construction of the Robert-Bourassa Dam was controversial due to its impact on the environment and the displacement of Indigenous peoples in the area. The dam and the James Bay project as a whole have been criticized for their lack of consultation with Indigenous communities and their negative impact on traditional ways of life.
History of Robert-Bourassa Dam Canada
The history of the Robert-Bourassa Dam can be traced back to the 1960s when the government of Quebec began exploring the possibility of developing hydroelectric power in the northern part of the province. In 1971, then-Premier Robert Bourassa announced the James Bay hydroelectric project, which would involve the construction of several dams and power stations along the La Grande River and its tributaries.
Construction on the Robert-Bourassa Dam began in 1974, and it was completed in 1981 at a cost of approximately CAD $15 billion. The dam was named after Bourassa in recognition of his role in initiating the James Bay project. At the time of its completion, the Robert-Bourassa Dam was the largest underground power station in the world.
The construction of the dam was a major engineering feat, as it required the excavation of over 150 million cubic meters (196 million cubic yards) of rock and soil. The project also involved the creation of a massive reservoir, which required the flooding of an area of over 2,800 square kilometers (1,080 square miles).
The Robert-Bourassa Dam has since become a major source of electricity for Quebec, providing power to the province's residents and industries. The dam has also helped to reduce Quebec's reliance on fossil fuels and has contributed to the province's efforts to reduce greenhouse gas emissions.
However, the construction of the Robert-Bourassa Dam was controversial, as it had a significant impact on the environment and the traditional ways of life of Indigenous peoples in the region. The dam and the James Bay project as a whole have been criticized for their lack of consultation with Indigenous communities and their negative impact on the environment and wildlife in the area.

Robert-Bourassa Dam Hydropower Plant Canada - Technology
The Robert-Bourassa Dam hydropower plant is a massive facility that generates electricity using the power of the La Grande River in northern Quebec, Canada. The plant is equipped with 16 vertical Francis turbine-generators, each with a capacity of 768 megawatts (MW), for a total capacity of 12,288 MW.
The turbines are housed in a large underground chamber excavated deep into the bedrock, beneath the dam itself. The water from the reservoir created by the dam is channeled through tunnels and penstocks (large pipes) to the turbines, where it spins the turbines' blades, driving the generators to produce electricity.
The facility also includes a large substation that transforms the electricity generated by the turbines to a higher voltage for transmission to Quebec's electrical grid. From there, the electricity can be distributed to consumers throughout the province or exported to neighboring regions.
The Robert-Bourassa Dam hydropower plant is a significant technological achievement, utilizing advanced engineering and construction techniques to harness the power of the La Grande River. It is a prime example of how hydropower can be used to generate large amounts of clean, renewable energy and reduce reliance on fossil fuels.
