Those Rp/kWh values (LV/MV/HV) are from the link Rocket provided. I now have him on ignore so can't provide the link myself sorry. From memory HV was around 990 Rp/kWh.
And Indo has voltage levels of 25/30/70/150/275/500 for HV and 6/12/20 for MV. The furnaces purchased (voltage rating 20 kV) would have been selected to match the Indo grid.
