The main design parameter for the station’s power system was efficiency. The quantity of Diesel fuel consumed at Dome C must be strictly limited both to limit local impacts and limit the quantities of fuel to be transported long distance by traverse then stored on-site. Under normal operations the fuel demand is only driven by the electrical load and by vehicle use. All space heating needs are met using the Diesel generator sets’ waste heat recovered from the jacket water cooling system and the exhaust.
The generator sets deliver an average of 110 kW electrical. The same power is wasted in the cooling system and the exhaust. This is a total of 150 kW of waste heat which is recovered and distributed inside the three station buildings through the heating circuit outlined in the diagram. Additional heat is generated within the buildings by all electrical appliances.
