Background:

The heating plant in Svenljunga was established in 1983 and has been operated by Solör Bioenergi since 2011. The heating plant consists of a wood chip-fired steam boiler and delivers both steam and district heating. To supplement existing heat production with its own renewable electricity production, Solör Bioenergi chose in November 2019 to invest in an ORC turbine. The following year, the heating plant was upgraded to a combined heat and power plant. The heating plant in Svenljunga is the third of Solör Bioenergi’s facilities that has so far been supplemented with an ORC turbine from Againity.

Our solution:

Againity delivered an automated ORC system with a maximum capacity of 315 kW electricity production. The ORC system enables electricity production from the heating plant’s steam boiler. In total, the system is expected to produce 1.36 GWh of electricity annually, corresponding to annual emission savings of 1,200 CO2 equivalents when substituting
coal-based electricity.
