Rattlesnake Ridge Wind Power Project

Rattlesnake Ridge Wind Power Project

The AUC has approved applications for a 117.6-megawatt wind farm in the Medicine Hat area  


The Alberta Utilities Commission has approved all applications from BHE Canada Rattlesnake G.P. Inc. for the Rattlesnake Ridge Wind Power Project, located southwest of Medicine Hat. The AUC issued a decision​ on the project on September 9, 2020.

BHE Canada Rattlesnake G.P. Inc. has been approved to:

  • Construct and operate a 117.6-megawatt (MW) wind power plant, consisting of 28 4.2-megawatt (MW) wind turbines.
  • Construct and operate a collector substation designated as the Rattlesnake Ridge 719S Substation. 
  • Construct and operate a 50-metre-long 138-kilovolt (kV) transmission line designated as Transmission Line 879AL. 
  • ​Connect the proposed power plant to AltaLink Management Ltd.'s existing 138-kV Transmission Line 879L.​

The AUC also approved applications from the ​Alberta Electric System Operator​ and ​AltaLink Management Ltd. to provide transmission system access to the wind power project, to alter and operate Transmission Line 879L, to construct Rattlesnake Ridge 719R Radio Site, and to connect the power plant to Transmission Line 879L.

BHE Canada Rattlesnake G.P. Inc. will require the use of access roads during its construction, operations and maintenance phases to access turbine locations. Upgrades to the existing public roads in the area for turbine and component delivery will also be required.

The proposed project will include an operations and maintenance building at the south end of the project next to the substation, a temporary laydown yard during construction, and may also require one meteorological tower.
