$10mil a year? WOW. I am surprised the execs wouldn't go for it. Well, not really. It's a no brainer, and sometimes they have no brains.
So get this, my home electric usage is actually similar this time of year, 12 000-19000 kwh. Same service amperage size too. The only difference is the shop is 3ph. $0.27 shop $0.11 house.
