Do we know if petamine is selling themselves electricity?
If so it should be less than $0.05 × 1.5 (PUE + hosting costs)
Even if they are buying electricity for $0.1/kwh they shouldn't be charging more than $0.15/kwh.
$0.45/kwh is ludicrous. How do we know $0.25 is anywhere near their costs when they managed to simply cut the price in half as soon as hosting costed ~50% of what they mined.
I bet they can go as low as $0.1/kwh and still profit. Especially if they are selling electricity to themselves.
We have a 350,000 Watt solar facility at site, which is owned by another company of us. To give you all an idea what this means:
In Belgium a 350kW installation has a yearly revenue of about 300,000 Kwh. The PetaMine consumes about 500 kw or 1285 kw after IPO (500*1 + 1000*0.785), this means between 4,380,000kwh and 11,256,600kwh each year. This is without any growth!
So our own electricity is only between 6.8% and ?? 1,1% of all electricity needed. What do you think such an installation costs?
