I find it strange that you pay 0,05 US for hydro power on Iceland. I pay 0,055€ for hydro power on Iceland for a farm of more than 200kW and thats only because i have been with them since beginning 2014, so one of the first i believe. In my price hosting, vpn is part of the price. Every 3-6 month I put out some inq. to other hosting companies on Iceland, and non of them is able to match my present price.
Im willing to dig in to this, so send me a PM with your hosting company and I will let them make me a quote.
One thing I came across is the possiblility to make my own building for my farm, but living expenses, hardware and internet gear eats up the bennefits.
I buy it directly from farmers (as in actual livestock farmer) that have their own hydro power, not a hosting company.
They include hosting and internet connection, they usually get considerably less selling their power to the grid (about 1-2 cents ). I provide them with an reasonable alternative by buying power at a higher rate than the power companies pay them. I move in the gear, they get a better price and have to give me some space which is usually abundant on livestock farms.
More importantly, I pay little for transmission since we don't buy much from the grid (or at all). Provided the mining gear is behind the metering station of the hydro generator you will only pay for power use that is in excess of the generator capacity.
Right now both my locations have limited capacities available, around 55 kW.
If you are interested in such arrangements you have to meet some of the livestock farmers, see if they have the capacity you need and negotiate with them individually. This is usually requires patience since farmers have very long time scales in their operations, they center their work around the seasons and you can expect to wait a few months before it's possible to move in gear.
There are locations that have power available in the 100-150 kW range but they are fairly remote, you can even find upwards of 1 MW sites that sell to the grid but would rather want to sell locally.
