Abwärme
There is a small power station comprising three Cummins B and C series diesel engines, offering an approximately 150 kVA 3-phase supply to most of the island buildings. Waste heat from the engine jackets is used for a district heating pipe. There are also plans to collect the waste heat from the engine exhaust heat gases to feed into the district heat network to improve the efficiency further. The power is normally switched off between 00:00 and 06:30.
