To fix the “problem” a helicopter is employed (burning aviation fuel) to spray hot water (which is heated in the frigid temperatures using a truck equipped with a 260 kW oil burner) on the blades of the turbine to de-ice them.
The aviation fuel, the diesel for the truck, and the oil burned to heat the water, could produce more electricity (at the right time to meet demand) than the unfrozen wind turbine could ever produce. (Before it freezes up again).
Apparently we need global warming to keep the wind gennies running to prevent global warming.
Thank goodness they didn’t waste the avgas and diesel on something silly like producing electricity.
