The Prince wind farm is a two-phase development, which involved the installation of 66 turbines with a generating capacity of 99 MW in Phase 1, while Phase 2 included 60 units for an additional 90 MW.

The total project consists of 126-GE Sle 1.5-MW wind turbine generators, with a combined capacity of 189 MW. The site is situated along a ridge parallel to the Lake Superior shoreline, with elevations up to 400 m above sea level. The area is within the rugged Canadian Shield with forested and undulating bedrock conditions.

Prince 1 construction began in September 2005 and Prince 2 construction commenced in February 2006. Turbine erection and commissioning for both phases was completed in November 2006.
