Your goal will be very hard without experience in growing, period!
If you live in an illegal state......Your looking at the possibility of major law issues!
They do track electrical usage in residential homes and even a home with a 200 amp box. Is going to be hard pressed to deliver what you want.
Sigh, Ok, here is some advise on how to overcome your electrical issues..... Buy a building that was an operating tool and die or heavy machine shop. Others would be any business that required high electrical amp/watt draws.
This covers use amounts. Your GOING to HAVE to cover scent elimination. These buildings usually have roof exhaust. This is good BUT, It MUST still be filtered!
Another plus for these buildings is that some have pretty good cooling to build on. High ceilings - so the use of DE bulb HID is clear! You want big harvest? Big plants go a long way to helping that, and keeping plant #'s down. High plant #'s can in some places....cause bigger legal issues! They will have sufficient water and drain availability, and have little to no windows to inside past the office area. You will have truck docks to load and unload your supplies with out drawing attention to the operation....
Get a tour of the building and look for petro chemical spills in/on the floor surfaces......Not the best choice but, usable.....You buy it and you could become liable for on-site pollution issues not disclosed in the sale or hidden and later discovered by off-site neighbors.....So ask about that on the land it's self...
Leasing is ok, as long as the lessor does not pop in for a visit at any time!
