The Alberta Utilities Commission is taking comment until Feb. 12 on an application by NaturEner Wild Rose 2 Energy to change the turbine size and uprate the total facility output for its Wild Rose 2 wind project in the Cypress County area.
The project has already been approved by the commission at the smaller size. Then NaturEner in December 2013 requested approval for an amendment that would change the approved Acciona 1.5-MW turbines to Alstom 3-MW turbines for the project. NaturEner said that the proposed change would result in:
- a reduction in the number of turbines from 108 to 63;
- a reduction in the number of turbines on native pasture, from 19 to 12;
- thirteen new turbines would remain at their previously approved respective locations or within 50 meters from the approved project layout;
- twenty-four new turbines would be located between 50 and 200 meters from their previously approved respective locations;
- twenty-six new turbines would be located greater than 200 meters from their previously approved respective locations;
- a reduction in the project area; and
- an increase in the nameplate capacity of the project from 162 MW to 189 MW.
The company said in the application: “From the time that project development and turbine selection began until the time that the Project’s interconnection permits were issued, wind turbine technology has evolved significantly in the direction of larger and more productive, more efficient, turbines. Some older turbine models, such as the Acciona 1.5 MW AW-77 (the ‘Acciona Turbine’), which was approved for use in the Project Permit, are no longer being produced and/or actively marketed. NaturEner conducted a multi-factor selection process for a replacement turbine and ultimately entered into a turbine supply agreement with Alstom Power & Transport Canada Inc. (‘Alstom’). Pursuant to this agreement, Alstom agreed to supply the Alstom 3.0 MW ECO 110 turbine (the ‘Alstom Turbine’) to the Project, subject to conditions which include regulatory approvals. As discussed in more detail below, the Alstom Turbine is larger than the Acciona Turbine, but also more efficient for the wind regime in the Project Area, resulting in the removal of 45 turbines from the Project.”
The company noted that the Alstom Turbine was recently approved for use at the Wild Rose 1 Project, owned by NaturEner’s affiliate, NaturEner Wild Rose 1 Energy.
