Ystad heating plant, Sweden

Ystad heating plant, Sweden


Ystad Energi AB owns the heating plant in Ystad, which produces 100% renewable district heating. The plant’s two main boilers have a capacity of 10 MW each and are mainly fired by chipped branches and tops that remain after logging. To become less dependent on electricity supply via the electricity grid, where capacity shortages are becoming a common problem, Ystad Energi chose to invest in three ORC turbines. The two 10 MW boilers will each be equipped with an ORC turbine and a third turbine will be connected to a 5 MW boiler.

Our solution:

Againity delivered three automated ORC systems with a maximum capacity of 750 kW electricity production. The ORC system enables electricity production from the boilers’ hot water. In total, the systems are expected to produce 3220 MWh electricity annually, corresponding to annual emission savings of 2,900 CO2 equivalents when substituting coal-based electricity. Ystad Energi has chosen to sign a service agreement with Againity to ensure a long service life and minimal maintenance.
