The Alberta Utilities Commission on Oct. 17 approved applications from Pteragen Canada Inc. for a time extension to complete construction of the Peace Butte Wind Power Plant and attendant Tothill 219S Substation.
“After consideration of the record of the proceeding, and for the reasons outlined in this decision, the Commission approves the time extension,” said the Oct. 17 order.
Pteragen is the owner of the Peace Butte Wind Power Plant and Tothill 219S Substation in the Medicine Hat area. The approved time extension is from Dec. 31, 2016 to Dec. 31, 2018, to complete construction of the power plant and substation. The delay applications were registered on July 4.
Pteragen stated that the uncertainty associated with the Government of Alberta’s Climate Leadership Plan, the transition of the Specified Gas Emissions Regulation to the Carbon Competitiveness Regulation and the unknown schedule for the accelerated retirement of coal-fired power plants made it difficult to finalize commercial arrangements for the project. Pteragen also stated that a time extension to the end of 2018 would allow it to participate in the Government of Alberta’s Renewable Electricity Program request for proposals, which it anticipated to call for submissions in the December 2016 timeframe.
Pteragen submitted a project change proposal to the Alberta Electric System Operator (AESO) to reflect the change to the anticipated construction completion date. The AESO approved the project change proposal on May 18, 2016.
The project consists of sixty 2-MW wind turbines, the Tothill 219S Substation and a 34.5-kV collector system consisting of underground and overhead power lines. The project is located near the village of Seven Persons in Cypress County, approximately 22 kilometers south of Medicine Hat.
