Phase 1 - Forty Mile Wind

Phase 1 of the Forty Mile wind project consists of 45 5.0 MW (megawatt) wind turbines, located on 64,000 acres of privately-owned farmland in southeastern Alberta, in the County of Forty Mile No.8. The Siemens SG 5.0-145 IIB turbines have a 107.5 m (metre) hub height and 71 m long blades. The project has a generating capacity of 202 MW of energy.

The Project

Phase 1 of the Forty Mile wind project consists of 45 5.0 MW wind turbines, located on 64,000 acres of privately-owned farmland in southeastern Alberta, in the County of Forty Mile No.8. The Siemens SG 5.0-145 IIB turbines have a 107.5 m hub height and 71 m long blades. The project has a generating capacity of 202 MW of energy, producing enough power annually to power 100,000 homes and offset 400,000 tonnes of C02e.

In addition to wind turbines, the site contains internal access roads for the turbines, a substation, meteorological towers with weather station equipment, a collector system, and a radar tower for aviation navigation.

ATCO acquired its ownership of this project from Suncor Energy in January 2023.

This project is only the first step for ATCO?s renewable plan at Forty Mile. By 2026, ATCO plans to complete construction on the 220 MW Forty Mile solar project. ATCO is also assessing the feasibility of developing a second phase of Forty Mile wind.

150 MW of this project is sold under long-term contract with the Microsoft Corporation, for a term of 15 years, to further their goal of being powered by 100% renewable energy by 2024. The rest of the power is sold to the Alberta Interconnected Electric System.
