even in a remote location I recommend this:
first- Dig a big hole for your generators to sit in, and line it with egg cartons, to include the top you should make for it (this will reduce the amount of noise to almost none),
second- convert your generators to use veggie oils instead of diesel or gasoline, it may cost a bit at first, but it will save you tons of bucks in the long run, and make way less pollution, and less chances of fire,
Third- Cover the top of your structure with soil that is native to the area (about 3 inches thick is perfect) and have some kind of vegetation growing from it (so line your roof to something resistant to the soil, and use metal for the roof), it would be way harder to detect the building from the air this way... especially if you painted it camo colors,
Fourth- run your electricity through a couple alternators to boost the efficiency of your generators.
Any cheap alternative methods of electricity is recommended... do it semi close to a really large water source (like within 5 miles), so you can dig a long trench from the water source to your spot, and run nice new piping to your spot to fill a reservoir tank that is on site (at least 6 inches deep).
I know some people that are doing it, and that is what they told me, and they also said: "Go Big or Go Home" because it wouldn't really be worth it otherwise. They are doing it in 50'x100'x20' (WxLxH) steel frame buildings that are in thickets of trees to cover them, and divide the buildings like 2/3 flowering and 1/3 vegging. They run 5 10,000w generators per building. I have no idea what their harvests are like, but I know that about two years after they started they bought new houses and cars, and started a few more "Grow Factories" as they like to call them. They started out running on regular fuels, but it cost them too much money, and they HAD to convert to make it worth it.
Good luck, that was the best advice that I got, and I got it from a people that are actually doing it in Colorado...
