TSE Turun Seudun Energiantuotanto Oy, Kakola’s heat pump station
Kakola’s heat pump station
TSE’s (Turun Seudun Energiantuotanto Oy) heat pump plant in Kakola utilizes wastewater’s heat in order to produce both district heating and cooling for buildings at Turku region. The plant was finished in Spring 2009 next to Kakola’s wastewater treatment plant and the second heat pump was installed in Summer 2013. With the help of heat pumps the remaining heat energy from the water can be recovered instead of discharging it directly to the sea.
The heat produced in the heat pump plant corresponds to the heating needs of ca. 24 000 citizens of Turku. The wastewater cools down in heat pumps while releasing the heat energy to the water circulating in district heat network, after this the cooled down water is still used to district cooling. The plant is situated in a cave inside of Kakola’s rock. Besides the heat pumps there is a cold water reservoir (16 000 cubic metres) which is used to level daily variations in the district cooling network.
