To be built on 17,500 acres of private land, the wind farm will feature 83 Siemens Gamesa turbine variants, the SG6.0-170 and the SG5.0-145, with 6MW and 5.2MW of capacity, respectively.

The 6MW turbines will have a hub height of 110.5m and a rotor diameter of 170m. The 5.2MW turbines will have a hub height of 95.5m and a rotor diameter of 145m.

This wind farm will be connected to the grid by a 12–15km transmission line. The power will be supplied to the Alberta Interconnected Electric System.

During the project’s construction, 250 full-time jobs will be created, and 15 permanent jobs will follow once it is operational.
