Doing the math here, I think I'll even be ok during summer pricing, which goes just over 12 cents/kWh.
Although, I have been wondering about the peak pricing option. Not worrying about it now, because I don't have enough machines yet, but if I had considerably more would it be beneficial to switch to the peak pricing and then shut down for five hours M - F. That's 25 hours of downtime out of 168 hours, skips 30+ cents/kWh and runs during off-peak for lower 7 cents/kWh.
If I ran straight through, the average would be about 12.05 cents/kWh. Less than the normal pricing by about .5 cents.
Sounds like more math. Let me take a swing at it using a 13.5TH 1452 (at the wall) Watts as a basis. Of course, everything would scale linearly with that. Lets calc on a week.
168 hours at $0.1205 = $20.24 for power and yields 13.5TH * 168 hours = 8.1648 EHashes = $2.4789/EHash
143 hours at $0.07 = $10.01 for power and yields 13.5Th * 143 hours = 6.9498 Hashes = $1.44/EHash
That is the cost side. You need to figure your profit side, subtract the cost, and see which is better.
Thank you ccgllc. I think my main question might be how ramp down/up with five hours of off time might affect it. I don't think it would be noticeable but I wonder how I might be able to calculate that.
