Background:
The heating plant in Elverum is owned by Eidsiva Bioenergi, a subsidiary of the Eidsiva Group which is the third largest district heating producer in Norway. The heating plant consists of a 10 MW hot water boiler from Jernforsen which is fired with recycled wood. To increase the share of renewable energy in the electricity grid and reduce the heating plant’s costs, Eidsiva Bioenergi chose to invest in an ORC turbine from Againity.
Our solution:
Againity delivered an automated ORC system with a maximum capacity of 450 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 2.1 GWh of electricity annually, corresponding to annual emission savings of 1,890 CO2 equivalents when substituting coal-based electricity. Eidsiva Bioenergi has chosen to sign a service agreement with Againity to ensure a long service life and minimal maintenance.
