Waste incineration plant in Elverum, Norway invested in a 450 kW ORC turbine
Background
The heating plant in Elverum is owned by Eidsiva Bioenergi, part of the Eidsiva Group, Norway’s third-largest district heating producer. The plant includes a 10 MW hot water boiler fired with waste wood. To increase renewable electricity generation and reduce operational costs, the company invested in an ORC turbine from Againity.
Our solution
Againity delivered an automated ORC system with a maximum electrical capacity of 450 kW. The ORC system enables electricity production from the hot water of the heating boiler. In total, the system is expected to produce 1.7 GWh of electricity annually, corresponding to annual emission reductions of 1,530 tonnes of CO₂ equivalents when replacing European marginal electricity. Eidsiva Bioenergi has signed a service agreement with Againity to ensure long lifetime and minimal maintenance.

Roy Hovden, Head of Eidsiva Varme Elverum
In a Norway that is expected to face a power deficit in the coming years, installing ORC units in more heating plants could be part of the solution to increase electricity production. One of the advantages of generating electricity with an ORC unit is that power can be produced when demand is highest, for example during the coldest days in the middle of winter.
