Watch an AUC hearing


The Alberta Utilities Commission (AUC), the independent utilities regulator, will be holding a hearing to review the applications and submissions received to consider the power plant applications received in Proceeding 27837. The AUC issued a notice of hearing on October 20, 2023. As of February 20, the Commission has placed this proceeding into abeyance.

SPWC Development GP Inc. has applied to construct and operate a wind power plant, and associated Willow Wind 2708S Substation and battery energy storage system, designated as the Willow Ridge Wind Project (the project).

The power plant would consist of 31 wind turbines, with each turbine rated at 6.6 megawatts (MW), with a total generating capability of 204.6 MW. The project turbines would have a hub height of 115 metres and a rotor diameter of 170 metres. The power plant would also include a 34.5-kilovolt gathering system, which would be used solely for collecting the electric energy generated by each turbine and transmitting the electric energy to the proposed Willow Wind 2708S Substation.

The project would be located in the Municipal District of Willow Creek No. 26, Alberta, approximately 7.2 kilometres south of the town of Fort Macleod. Specifically, the project would be located within townships 7 and 8, Range 25, west of the Fourth Meridian, and townships 7 and 8, Range 26, west of the Fourth Meridian.

The Willow Wind 2708S Substation and the battery energy storage system would be located in the northwest quarter of Section 7, Township 8, Range 25, west of the Fourth Meridian.
