Vattenfall's heat production in Vänersborg utilises waste heat from the company Vargön Alloys as far as possible. Bio-oil has been used as peak and reserve power since 2003.
The Vänersborg plant was commissioned in 1985. Since 2017, Vänersborg's district heating network has been connected to Trollhättan's, which means that the waste heat from Vargön Alloys can be utilised even more efficiently.
In 2025, the Vänersborg facility was expanded to meet the growing demand for district heating. The new plant, named 'Lignum' (Latin for 'wood'), uses wood pellets, a by-product of the forestry industry.
