Hydro-Québec announced it will begin modernization work on the Trenche generating station on the Saint-Maurice River. $1.25 billion will be invested by 2034 to ensure the plant’s sustainability. This work aims to extend the life of this facility, which is celebrating its 75th anniversary this year . Replacing the six turbine-generator units with state-of-the-art models will also increase the plant’s installed capacity by approximately 15 per cent, from 302 to 350 megawatts, without changing the flow of the river. “We need to double our production capacity over the next few decades to achieve the energy transition. Increasing the power of our existing power plants where we can is a way to capitalize on our assets while limiting environmental impacts,” said Michel Charron, vice president – ??Construction Projects at Hydro-Québec. “The Trenche is the largest power plant on the Saint-Maurice. Given its age, it is necessary to ensure its sustainability, and its rehabilitation will ensure that it benefits all Quebecers for many years to come.” The rehabilitation of the Trenche development is a major project requiring two years of preparatory work. This will begin in January 2025 and continue until 2027. The turbine-alternator units will be replaced at a rate of one per year from 2027 to 2033, at the same time as work will be carried out on the upstream and downstream decks. Finally, work inside the building will be carried out in 2034. |
