49.9 kW electricity production at the district heating plant in Bräkne-Hoby
Background
Ronneby Miljö & Teknik operates district heating production based on renewable fuels. To increase local electricity generation and strengthen energy resilience, the company invested in an ORC turbine.
Our solution
Againity delivered an automated ORC system with a maximum electrical capacity of 49.9 kW. The ORC system enables electricity production from the hot water of the heating boiler. In total, the system is expected to produce 300 MWh of electricity annually, corresponding to annual emission reductions of 270 tonnes of CO₂ equivalents when replacing European marginal electricity. Ronneby Miljö & Teknik has signed a service agreement with Againity to ensure long lifetime and minimal maintenance.
