Haapajärven Lämpä Oy was founded in 1979 in Finland and has since been responsible for the production and distribution of district heating in Haapajärvi. Today, the plant has an annual heat production of approximately 34 GWh. The boiler is fired with renewable fuels such as bark, wood chips, sawmill by-products and wood from local sawmills. The addition of the ORC system is in line with Haapajärven Lämpä Oy’s ambition to maximize the value of the resources they use and contribute to a sustainable society, motivated by lower energy costs from the ORC system.

Againity delivered an automated ORC system with a maximum electrical capacity of 250 kW. The ORC system enables electricity production from the hot water of the biomass boiler. In total, the system is expected to produce 1,102 MWh annually, corresponding to emission reductions of 1,032 tonnes of CO₂ equivalents when replacing European marginal electricity.
