The Paintearth Wind Project (PWP) began development in 2011 and includes approximately 31,000 acres of land located forty kilometres (km) southeast of the Town of Stettler. The PWP is located on privately owned cultivated and grazing land and will generate clean energy while allowing landowners to continue with their daily activities. The project area has an excellent wind resource which has been verified with over three years of collected onsite wind data.

In 2017, the Paintearth Wind Project LP (PWLP) applied for approval from the Alberta Utilities Commission (AUC) for a 44 turbine, 150 megawatt (MW) wind power plant, and a permit and licence for the Lanes Lake Substation. The AUC application was amended in 2018 to reduce the number of turbines and modify the nameplate capacity of the PWP, and the PWLP received a power plant approval and substation permit and licence from the AUC in January 2020. PWLP submitted a Letter of Enquiry (LOE) in 2022 to address additional changes, including a reduction in the number of turbines to 38 turbines, a change in the model of the wind turbine, an increase in rated capacity per turbine from 3.6 MW to 5.0 MW, an increase in total plant capacity from 151.2 MW to 198 MW, and some spatial relocation of turbines, access roads and collector system routing. Updated approval for the PWP was received in the summer of 2022 and construction commenced in September 2022.

Construction of the PWP will involve the installation of thirty-eight (38) Siemens Gamesa Renewable Energy (SGRE) 145-5.0 turbines, an underground collector system, access roads, upgrades to existing roads, and the construction of a new collector substation (the Lanes Lake Substation). The PWP nameplate capacity will be 198MW. The project layout is available here.

Construction has resumed at the PWP for 2023 and the project contractor, Borea Construction ULC, mobilized on-site at the beginning of March. The following is a high-level schedule of key activities in 2023, which may be altered by weather and other unforeseen events. We will notify you again if the schedule changes significantly in the future:

  • Completion of Access Road Construction and Road Upgrades: Spring/Summer 2023
  • Completion of the Lane Lake Substation: Summer/Fall 2023
  • Turbine Foundation Installation: Spring to Fall 2023
  • Turbine Deliveries and Erection: Summer to Fall 2023
  • Collector Line Installation: Spring to Fall 2023
  • Project COD: Spring 2024

As of the beginning of July, all the access roads and approximately 66% of the collector lines have been installed. Foundation pouring is underway and expected to be completed before the end of summer. Construction at the Substation and the O&M Building is also underway and on schedule.

Turbine delivery is staring in July and there will be increased traffic on the road. The haul route map is available here. We will be sure to implement dust control measures appropriately as the traffic increases.

PWLP has engaged local landowners and stakeholders throughout the project development process, and we will continue to do so in a way that respects the community members’ needs. If you have any concerns or questions about the PWP in 2023, please contact the new Construction Manager for the PWP: Silvio Martinez over the phone (403) 471-9757 or email at: smartinez@potentiarenewables.com.

Construction activities will resume in March 2023 and be in full swing until the end of next year.

September 2022:

PWLP is commencing construction on September 19, 2022. Construction this fall is expected to be limited to setting up the laydown area, building new access roads and some turning radii, clearing turbine pads, upgrading some of the existing roads, and commencing construction at the Lanes Lake Substation. There will be a slight increase in traffic on the road this fall as the contractor and PWLP get organized at the Project site. The project layout is available here.
