We'll all be sending our miners to data centres in Russia at this rate - Russia 2.4 to 9.58 c/kw according to Wikipedia
I was able to find space mainland USA with 2c offpeak & 3.5 cent peak rates, which is where the miners are going...
and where exactly are your miners? plugged in at a power plant near you?!?
No... my apartment/soon to be warehouse

In the US don't forget there is a 'transmission charge' also. Here in the wonderful state of NJ, it is $0.12 Kwh. Now add the $0.067 transmission charge for a marvelous total of $0.187 Kwh.
Most of the 'alternative' electric companies fail to mention that you are still going to get charged for transmission. So the guys that are offering $0.10 Kwh, your final cost is $0.167.
Lets see: 750 Watt 400Gh/s miner - from .187 to .167 yields a savings of $131 per year; and from .187 to .08 yields a savings of $600 per year, down to $579 per year.
I did a search for Russian electric costs, found a .pdf at academia.edu... $.08 Kwh this year, $.10 Kwh next year and rising $.01-.02 cents each year until 2020. This is because they are going the deregulation route.
Really, if you are going to use COMED RRTP program, watch that 4pm spike to $.078 Kwh. Oh to be in Illinois again.

The rates everywhere are high, going to impact ROI in the long term. In MA i'm paying .14 through a local muncipality, nearby towns are paying .17-.18.
My partner and I found a site where we can get .04 at commercial rates. He's a network specialist so we're working on leasing the space and setting up hosting with it's own pool. Costs should be significantly less this way.
