OP said his costs were fixed.
We've been in a fixed cost contract for 10+ years at this facility. No break out of usage, power, etc. There used to be upwards of 300 1U servers running there, but it's probably down to 50 at this point. The facility seems to be well under capacity compared to a decade ago.
To give you an idea right now, 150 Th/s on an S9 SHA 256 miner gets you about $200/day.
This is 15.0 TH/s for an S9, right? So more like $20/day? Thanks for the useful info!
Not 220V?
Trying to see if we can swap out the power in one of our cabinets and install something like:

Realistically maybe 4x. So a 42U cabinet with two of them could power 8x.
