The Courtenay wind farm was originally proposed as a much bigger project, but after concerns over a nearby airstrip, the developer more than halved the number of turbines in the proposal.
A turbine supplier has not yet been named, but the 100 turbines will have a power of 2MW each.
The turbines will be spread across the 85-square-kilometre site. Construction of the $350 million project is expected to begin in June 2014, with comissioning set for the end of the year in order to qualify for the production tax credit.
Xcel Energy will buy the power produced by the plant after signing a long-term power purchase agreement with Geronimo.
