Most of the power is going to come from the vacuums, the spindle and your air compressor. So, for example, if you've got a 10hp spindle, two 20 hp vacuum pumps and you're using 10cfm air (from your 15hp compressor which puts out 50cfm) your max hp draw is 53. 1hp is about 750 watts - your wattage is about 40,000 watts or 40KW.
