Background:
The heating plant in Töreboda, which is owned by VänerEnergi AB, is located next to Moeleven’s glulam factory and uses their residual products in the form of cutter chips to produce district heating. To increase the share of planned energy and produce electricity during the winter when the need is greatest, VänerEnergi chose to upgrade its heating plant in Töreboda to a combined heat and power plant with the help of Againity.
Our solution:
Againity delivered an automated ORC system with a maximum capacity of 49.9 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 265 MWh of electricity annually, corresponding to annual emission savings of 238 CO2 equivalents when substituting coal-based electricity. VänerEnergi has chosen to sign a service agreement with Againity to ensure a long service life and minimal maintenance.
