1987
Hydromega becomes Quebec’s first independant producer within the small hydroelectric generating stations policy established in 1987 by Quebec’s government and Hydro-Quebec.

The Mont-Laurier generating station was built in 1937, expanded in 1951 then abandoned as ruins before being acquired. Hydromega engaged in the complete rehabilitation of the installations. The work lasted from November 1987 to June 1990.

Located on the South shore of Montreal, near the town of Sainte-Catherine, at the lock of the Saint-Laurent seaway, the Côte Sainte-Catherine Phase 1 was the second project undertaken by Hydromega. The Côte Sainte-Catherine generating station is particular since its production is higher in winter than in summer.

Hydromega acquires the facility and the rights for hydroelectric prodution of the SM-1 site. This generating station is located on the first fall of the Sainte-Marguerite river, 25 km West of Sept-Iles. In the beginning of the 20th century, the site had been equipped to produce the mechanical force necessary for the manufacturing of pulp. Gulf Pulp & Paper, owner of the manufacture, abandoned its operations in 1967.
