Tempest

The Tempest Wind Power Project (the Project or Tempest) was submitted to the Alberta Utilities Commission (AUC) on December 20, 2022 (Proceeding 27726). The Project, as applied, is a 99-megawatt (MW) wind project located approximately 15 km east of Stirling, Alberta in Warner County. The Project will consist of 22 Vestas, V150 4.5 MW wind turbine generators.

TransAlta Corporation (TransAlta) through its wholly owned subsidiary TransAlta Coaldale Wind L.P. by its General Partner TransAlta Coaldale Wind Inc. plans to build, own and operate the Project. Current target commercial operation date for the Project is June 2025. As part of our ongoing development efforts, TransAlta has completed the full suite of studies and consultation required by AUC Rule 007; continues collecting wind data and advancing its engineering efforts; and advancing the project through the AESO interconnection queue. A transmission line to connect the Project to the grid will be applied for under a separate application. This webpage will be updated with new information as it becomes available.
