All or nothing attitudes result in the latter
I'd take the lower output for the deicing system than no output
I really don't know why de-icing is such a big deal in this thread... I mean, wind turbines have been employed in much colder regions - and deicing systems have been installed (ranging from microwave, thermo-electric and heated pneumatic jets). In Pori, Finland - electro-thermal deicers use ~1% of the annual output (yes, that's a lot - but no where near "a large part". There's more energy in cold wind - but not so much with a frozen blade (not to mention potential risk of overloading due to excessive weight)
I know it's nit picky - but I'm anal about it.... Power plants generate power - not energy
