I'm wondering about the repliers putting the decimal point in the correct place in the replies.. 0.002USD/kWhr means 0.2 cents per kWh which is insanely cheap..!
Here in Australia, flat tariff prices were $0.36/kWhr which is 36 cents per kWh.. though we had a price drop recently down to 27c/kWhr. We also pay a network access fee of $1.50 per day. 1 Oz dollar = 0.72 USD
With miners returning maybe 16c/kwhr then it is not productive to mine here.. I'm setting up my mining system to use my 400kW solar farm as I can't sell my power to the network for more than 6c/kWhr.
If you have power at only 0.2 cents per kWh.. can we be friends. I have a bunch of miners I can send over to run

0.2 USD/KWh is my rate, yeap....
However, finding a place to host a large amount of miners is a feat, as i'm looking already for someone that asked me and i haven't found a single place i could consider without making a considerable investement on power transformation.
So, for small scale mining, it is good, but for large scale (PH/s domain) it is a no-go atm.
