Researchers report that misaligning wind turbines with respect to the incident wind in order to deflect the turbines' wake away from downwind turbines yielded a 7-13% increase in total power production and a 72% reduction in the variability of power production for near-average wind speeds, relative to the historical baseline, in field experiments on an array of 6 turbines over a 10-day period at a wind farm in Alberta, Canada.
