Hydro-Qu�bec signs 25-year PPA for 147 MW Mont Sainte-Marguerite Wind Project

SAN FRANCISCO, Feb. 13, 2015 -- Pattern Energy Group LP ("Pattern Development") today announced that its Mont Sainte-Marguerite Wind project has entered into a 25-year power purchase agreement (PPA) with Hydro-Qu�bec. The 147 megawatt (MW) project is located approximately 50 kilometers south of Qu�bec City, in the Chaudi�re-Appalaches region. Pattern Development has partnered with Renewable Energy Systems Canada Inc. (RES Canada) on development of the project.

"This project marks our expansion into Qu�bec and further reinforces Pattern Development's track record as one of the top wind developers in the country," said Mike Garland, CEO of Pattern Development. "We look forward to working with RES Canada to build a world-class wind facility that will help Hydro-Qu�bec reach its renewable energy goals. We will be using Siemens turbines and locally-sourced turbine components, supporting manufacturers in Qu�bec. We are proud to be hiring from Qu�bec, bringing jobs and economic benefits to the Chaudi�re-Appalaches region."

The Mont Sainte-Marguerite Wind project will utilize 46 Siemens innovative 3.2 MW direct drive wind turbines. Components for the turbines will be sourced from Qu�bec and leverage the highly-skilled labor force and manufacturing facilities in the province.

The project will provide more than $735,000 annually to Pattern Development's community partners, the municipalities of Saint-Sylvestre and Saint-S�verin, which are active participants in the development of the project.

The project will employ approximately 200 skilled workers on site at the peak of construction activity and create 10-12 permanent jobs once operational. Upon completion, the Mont Sainte-Marguerite Wind project is expected to generate enough power for approximately 27,000 Qu�bec homes annually, according to power use statistics from Hydro-Qu�bec. The project site, which is located on one of the higher elevations in Southern Qu�bec, has one of the strongest wind resources in the entire region.

Pattern Development acquired RES Canada's stake in Mont Sainte-Marguerite Wind and now owns 100% of the project. RES Canada and Pattern Development will continue to jointly develop the project, which is expected to begin construction in the third quarter of 2016. The project is expected to reach commercial operation in December 2017.
