The Prince Wind Energy Project comprises 126 wind turbines extending over nearly 20,000 acres. With a total installed capacity of 189 megawatts (MW), Prince is now the largest wind farm in Canada.

Completed in November 2006, the Prince Wind Energy Project is located northwest of Sault Ste. Marie in Northern Ontario. The project was constructed in two phases, each with its own 20 year power purchase agreement with the Ontario Power Authority.

Avery Construction was responsible for building 48KM of 10M wide primary access road throughout the entire site which involved many hectares of forest being cleared and harvested as well as hundreds of thousands of cubic metres of aggregate being moved. Avery Construction was also responsible for the installation of culverts and the preparation of all 126 wind turbine foundations.
