Garden Plain

The 130 MW Garden Plain Wind Project is located on approximately 14,000 acres of privately-owned land north of Hanna and south of Castor, Alberta, in Paintearth County and Special Area No. 2.

Recognizing the many positive attributes that this site holds, from its desirable wind resource, environmental suitability, and proximity to transmission, TransAlta completed the necessary permitting and regulatory requirements and submitted a facilities application to the Alberta Utilities Commission (AUC) to seek a permit to construct and license to operate the facility. 

In April 2019, the AUC issued its decision regarding TransAlta facilities application and granted a permit and license for the Garden Plain Wind Project.

In May 2020, TransAlta entered into a long-term Power Purchase Agreement with Pembina Pipeline Corporation for the offtake of 100 MW for an 18-year term.
