Default generator cost and fuel consumption

Hi again MG WIllia--

I know you asked for Kohler figures, but I thought I would give you my Generac figures, so you at least have a ballpark. 20KW with 100 amp automatic transfer switch, $9500.00, which included all parts, delivery, installation, etc. Purchase price is directly proportional to KW size of the generator. (Note that this is at my primary home in CT where EVERYHING is expensive. NH figures may be less). I use propane fuel and it burns approx. 3 gallons per hour. Current cost of propane is around $2.80-ish per gallon. I have a 500 gallon propane tank and could therefore go almost a week on the generator 24 hours per day.

good luck.

MM
