This 1,550-MW hydroelectric complex on the Romaine River involves four generating stations and reservoirs spaced over 150 kilometres along the Romaine River, located on the North Shore of the Gulf of St. Lawrence. Each station will have an associated rockfill dam, two generating units, and a spillway. One permanent access road 150 kilometres long will also be built as part of the project linking the generating station to the regional highway. Hydro-Québec began its work in summer 2009. Romaine-2 was commissioned in 2014, followed by Romaine-1 in 2015, and Romaine-3 in 2017. Work on Romaine-4 is underway, and includes building of all the structures associated with a new power generation facility: generating station, dam, diversion, spillway, tailrace canal, headrace tunnel, etc. Excavation of the spillway and water intake, along with the temporary diversion structure, were completed in 2018. In 2021, Romaine-4 reservoir filling was finished and construction work on Romaine-4 dam was completed. Concreting at Romaine-4 generating station will continue in 2022 and the project is expected to be commissioned in the last months of 2022.
