"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?"

I think you don't understand...the electricity produced from the 350k solar plant is only about 1-6% of all electricity used by the PetaMine.
