E.ON seeks approval for 120-MW Canadian wind project

E.ON Climate & Renewables Canada Ltd. is proposing to construct and operate the 120-MW Grizzly Bear Creek Wind Power Project in central Alberta, southwest of the community of Vermilion.

The project consists of 50 wind turbines of 2.4 MW of capacity each, achieving a nameplate capacity of 120 MW, the company told the Alberta Utilities Commission in a July 9 combined application for approval of the wind farm and a substation that will serve that facility.

E.ON representatives met with officials in the county of Minburn and the county of Vermilion River on several occasions, the application noted. Minburn County will host 45 of the turbines while Vermilion River County will host five turbines. The turbines are the Nordex N117/2400 IEC III model. The Nordex N117 turbines each have a capacity of 2.67 MVA, with total site nameplate capacity to be rated at 126.3 MVA and total site gross capacity at 133 MVA.

The targeted commercial operation date for this project is Dec. 31, 2016. “Approval for the proposed Project is required by April 2015, for a commercial operation date of December 2016,” the application said. “Generally, long lead times for equipment procurement are required for scheduling construction in the summer of 2016. If the approval date cannot be met, construction would be pushed into the winter months to meet the Project In-Service-Date and possibly be delayed until the next spring (2017) construction season. This would result in increased construction costs and lost wind energy production revenues.”

The Grizzly Bear Substation high side voltage will be designed for 230 kV (originally operated at 138 kV prior to being switched to 230 kV) and the low side will be 34.5 kV. The substation will consist of a single 140 MVA main power transformer. The transmission line will run about two kilometers from the applicant substation to an under-development transmission line from Tenchbray to Vermilion. The substation location was chosen as it represents a central location within the project area and will require limited transmission by ATCO to connect to the grid.
