The agreement says the power station will guarantee up to 20 MVA, that's enough for the first 2 furnaces.

And according to this research note

A price of 0.11 USD/kWh is a fair assumption.

0.11 USD/kWh is currently 1540 Rp/kWh, which is higher than the price that Low Voltage (LV) connections (households essentially) currently pay in Indonesia. Medium Voltage (MV) connections (which is what GMC will have) pay 1114 Rp/kWh, or 0.079 USD/kWh.

So, do we think they're undisclosed agreement (which is commercially sensitive by the way) is ~38% higher than the going rate for MV connections? If so then its close to what the research note has assumed and GMC still make a healthy profit. It's more likely to be closer to 0.079 USD/kWh than 0.11 though.

Yes they need to pay for at least 40 hours a month (USD 61k/month), this is nothing, and not the concern, the concern will be why the furnaces are down...

And PT PLN is state-owned, it's not going anywhere
