>Modern wind turbines generate ~ 1 Megawatt of power. That is a big number. After applying the 'capacity >factor' (the fraction of max. that you can hope to get 365 24/7) of ~ 35% that is still 350 Kilowatts. I have no feel >for these things but that is still a big number.

If 350 megawatt-hours is 1/8 of the annual power used at Bolton, their annual power use runs to 2.8 gigawatt-hours, heavily loaded in the December/January snowmaking season- not the summer air-conditioning period.

FWIW: The mill at Jiminy Peak is rated 1.5 megawatts peak and sports 37-meter (121 foot) blades- about an order of magnitude more mill than the Bolton unit.
