Project Description

In December 2018, the Government of Alberta announced that TransAlta’s Windrise Wind Project was selected as a successful proponent as part of the Alberta Electric System Operator’s (AESO) Renewable Electricity Program (REP) Round 3 process. The 207-megawatt (MW) Windrise Wind Project will contribute to the Government of Alberta’s target of 30 percent renewable electricity by 2030.

In order to connect the Windrise Wind Project to Alberta’s electricity grid, TransAlta will construct the Windrise Transmission Project (the Project). The Project will connect the proposed Windrise Wind Project Substation to the existing Windy Flats 138S Substation through a 138,000 volts (138 kilovolts) transmission line.

Single steel pole structures will be used for the Project.
