The 23 Vestas 400kW turbines will be removed from the 22-year-old project, and replaced with nine Gamesa G80-2MW turbines in 2016.
The repowering will double the project's capacity, using half the number of turbines, said the manufacturer. The current 23 Vestas turbines total 9.2MW.
Yorkshire Windpower, a 50-50 joint venture between E.on and Energy Power Resources, owns Ovenden Moor.
An 80-metre temporary met mast was installed at the site in March 2013 to help the project owners decide which turbines to use. Gamesa's G80 is designed for high-wind sites and has a cutout speed of 25m/s.
