The Australian Antarctic Division employs a co-generation system to heat Antarctic Stations. Waste heat created by diesel generators is used to heat water. This water is pumped around station as part of the site services to provide heating for each building.
By analysing how much heat is lost from the water after it has been pumped around the station, the amount of heat energy being used can be calculated. This is known as the thermal load, measured in kilowatts (kW). Buildings can also be examined on an individual basis to locate any inefficiencies.
