Wow, the norm around where you are is 80kw generators? Must have a bunch of electricians smiling ear to ear... a 60kw single phase generator can push 250amps... and that's a bone that we get tossed only once every now and again.

Just sell them a generator, a natural gas connection and then convince them they need it to be on an automatic transfer switch - then find an electrician and plumber and make some nice referral fees.
