The district heating plant in Svenljunga complemented steam from its wood chip boiler with an ORC turbine
Background
The district heating plant in Svenljunga was established in 1983 and has been operated by Solör Bioenergi since 2011. The plant includes a waste wood-fired steam boiler and supplies both steam and district heating. To complement its existing heat production with its own renewable electricity generation, Solör Bioenergi chose in November 2019 to invest in an ORC turbine. The following year, the plant was upgraded to a combined heat and power (CHP) plant. The Svenljunga facility is the third of Solör Bioenergi’s plants to be equipped with an ORC turbine from Againity.
Our solution
Againity delivered an automated ORC system with a maximum electrical capacity of 315 kW. The ORC system enables electricity production from the plant’s steam boiler. In total, the system is expected to produce 1.36 GWh of electricity annually, corresponding to annual emission reductions of 1,200 tonnes of CO₂ equivalents when replacing European marginal electricity.
