This post provides data current to June 30, 2010 on the productivity and variability of output of Ontario’s wind farms. The tendency of more productive wind farms to produce power with greater annual variability of output is observed. An error in the data reported in the April 6, 2010 edition of the report with respect to Prince Farm is noted and corrected in this edition. The life-to-date capacity factor of Ontario’s large wind farms considering only full power years is 29.0%.
