Industrial wind turbines (IWT) had delivered 83.3 TWh and curtailed 10.5 TWh over that time.  The combined cost of the generation and curtailment represented an average delivered cost per kWh of 15.32 cents without factoring in costs of gas plants being at the ready when the wind wasn’t blowing or spilling clean hydro.
