Main power house
Apart from the expeditioners, the main power house is the life line of the station with four generators that supply power and heat to the station buildings. The heat energy that is produced by the engines is captured through water heat exchange units and then circulated around the station via a complex site services system. The pipe and cable system is all above ground and often in the winter months will be buried under snow. The hot water enters each building passing through a heat exchange unit before circulating back to the main power house to be reheated and start the cycle over: this runs 24/7. The number of engines that are running at any given time is related to the power load required.
