Back when hurricane Sandy hit, there was a neat appearing resi, uoscale, probably in the 1mil plus range that had the on grade level flodded out. Power was cut, like the rest of that town.
Turns out about 6 weeks after the locals were allowed back, a local cop noticed activity at that house, in the dark. Turned out the grade level (4 car garage; 2 wide, 2 deep, plus the 20’ deep balance was a ‘farm operation’ and not ‘grow your own’! 3 guys arrested, and the house was seized, and later found to have been in foreclosure.
Lighting was 36-400 watt metal halide fixtures, roughly 15KW. The lighting, and a front & rear doorway light were the only items on the 400/320 service.
Depends on the quantity of crop I guess.
