Rattlesnake Ridge Wind Power Project

Rattlesnake Ridge Wind Power Project

Applications for a 117.6-megawatt wind farm in the Medicine Hat area  


The Alberta Utilities Commission is currently considering an application from BHE Canada Rattlesnake G.P. Inc. for the Rattlesnake Ridge Wind Power Project, located southwest of Medicine Hat. The project would consist of 28 4.2-megawatt (MW) wind turbines generating and a proposed Rattlesnake 719S Substation which would connect to AltaLink Management Ltd.’s existing Transmission Line 879L.

BHE Canada Rattlesnake G.P. Inc.'s application is seeking flexibility to change the turbine model and locations, pending on-going discussions with turbine manufacturers. The only current anticipated change would be removing two turbine locations and using turbines with a slightly higher nameplate capacity. The collection system would consist of underground cables connecting each turbine to the project substation. 

BHE Canada Rattlesnake G.P. Inc. would 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 would 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.
