Eastern WA (Avista) is at 0.07something with a $8 minimum (not in addition, but as a credit unless you don't use $8 of electricity) but if you run a farm it can be as low as 0.04kwh. When I lived there it was 0.065. There are still a ton of rebates and whatnot you can finangle your way into - I think I got it down to 0.06 for straight residential at one point. The lack of income tax might help as well, and rent's cheap as fuck - my apartment in NYC is the size of the kitchen in WA and cost 4 times as much. So 600sqft for $425 with everything included in the end except electricity and internet - and some places do actually include electric - with no income tax, I'd say it's a decent deal except you have to at least spend some time in Eastern Washington. Great place if you are in the right line of work, shit place otherwise.

Also, dude who claimed Indonesia was dominated by the British, you mean the Anglo-Javanese expedition under Sir Stamford Raffles between 1811 and 1814 with a total of 45 days of fighting and only on the island of Java? I don't think they had electricity back then. America subsidized a lot of it after the Konfrontasi in the early 60s til the Asian Financial Crisis and I'd be pretty careful calling the country stable since you got issues in Aceh, ethnic divisions, and any internal strife is one helluva wild card. At least the only two problems in Washington/Idaho are meth and white-supremacists-sovereign-citizens.

In fact, if this is at all a long-ish term investment I'd be very careful on relying on subsidized electric rates and take it for granted. Anyone who's played Transport Tycoon (Deluxe, hopefully) knows that subsidies can't really be replied on and in the US it's going away slowly as more domestic oil reaches the market. Northern Idaho's seeing about a 1% increase a year now. There's a general lack of transparency in rates and it's pretty confusing but I'd say you should consider Texas, especially places like Austin if you can find reasonable space - where commercial base tariffs are pretty low for your demands and transmission only applies in certain circumstances. 0.025 or so to start for commercial at your level of need, I think.

Oh, Native Americans will always have an advantage in tax credits and if you have an in on 2/3 of any sovereign tribe please contact me immediately (best I got was 2/5) because it may be one hell of a win-win-win situation if you can swing something like that. Tribes have been overproducing if they're involved and a few attorneys and I have planned a perfectly legal in every possible way, beneficial in increasing infrastructure and employment, have essentially no risk (we ran it by the BIA already and state agencies), and am incredibly lucrative way for a tribe to make a ridiculous amount of money in addition if only the tribal council would agree to it by an overwhelming majority, in exchange perhaps there's free or really cheap land/power for you to mine coins. Unfortunately while all the principle parties on this end are actually minorities or of mixed heritage nobody is a member of a tribe so we haven't gotten very far in convincing more than just a few on any tribal council in several states.
