VänerEnergi AB (49.9 kW)
Background
The district heating plant in Töreboda, owned by VänerEnergi AB, is located next to Moelven’s glulam factory and utilizes its by-products in the form of wood shavings to produce district heating. To increase the share of dispatchable energy and generate electricity during winter when demand is at its highest, VänerEnergi chose, with the help of Againity, to upgrade its heating plant in Töreboda to a combined heat and power (CHP) plant.
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 265 MWh of electricity annually, corresponding to annual emission reductions of 238 tonnes of CO₂ equivalents when replacing European marginal electricity. VänerEnergi has signed a service agreement with Againity to ensure long lifetime and minimal maintenance.
