Commercial commissioning of the Seigneurie de Beaupr

Boralex Inc. (“Boralex”), Gaz Métro Limited Partnership (“Gaz Métro”) and Valener Inc. (“Valener”) are pleased to announce commercial commissioning of the first 131 MW of the Seigneurie de Beaupré Wind Farms within the projected time frame.

“After more than eight years of hard work by the Boralex and Gaz Métro teams, we are proud that the first 62 turbines are supplying green energy to Québec’s power grid,” stated Sophie Brochu, President and Chief Executive Officer of Gaz Métro, and Patrick Lemaire, President and Chief Executive Officer of Boralex.Within the next few days, an additional 141 MW will also be commissioned, thereby completing the largest phase of the Seigneurie de Beaupré Wind Farms.

We would like to highlight the vital contribution of many actors who made
possible the commissioning of the 272 MW Phase I on schedule: Séminaire de Québec, the owner of the land; Borea, the contractor responsible for
construction of the roads, collector systems and the substation; Enercon, the turbine manufacturer of the 126 wind turbines; and elected officials of the region and a large number of local enterprises.

Mr. Jacques Roberge, Superior General of the Séminaire de Québec, noted that, “concluding this important step on schedule is proof that we are working with quality partners, Québecers no less, and we are extremely happy that we will be continuing a long-term relationship with them to operate and develop the site.”
