Where do you live, Hawaii? Break-even is around $.20/kwh on a decent rig. The days of running a farm with electricity rates that high are over. Liquidate your hardware now.
Tawsix said below he pays $.15/kWh during the day and $.08/kWh during the night. My guess is that he made the mistake of building a farm mostly from 5830s which have terrible power efficiency. At $.15/kWh his cost of production on a 5830 is about $5.9/BTC, clearly losing money when the exchange rate is $4.8/BTC.
**Something I didn't take into account when calculating power costs: I have a variable rate where 10am-7pm is charged at ~15 cents / kWh and 7pm-10am is charged at ~8 cents / kWh, so that drastically lowers operating costs**
Tawsix: I suggest you stop operating during the day to profit from lower night rates.
