Heat-only and combined heat and power plants in Finland consumed 20.8 million m3 of solid wood fuels, equal to 40.8 TWh, in 2025, down 5% from 2024, according to preliminary data from the Natural Resources Institute Finland (Luke).
Forest chip consumption fell 13% to 9.1 million m3. Combined heat and power plants used 5.6 million m3 of forest chips, down 13%, while heat-only plants used 3.5 million m3, down 14%.
Of all forest chips, 6.3 million m3 came from roundwood. The use of roundwood chips fell 17% from the previous year. Logging residues totaled 2.6 million m3, down 3%, and stump use fell by one-tenth to 0.2 million m3.
Forest industry by-products totaled 10.4 million m3, up from the previous year. Bark accounted for 6.4 million m3, up 7%, industrial chips totaled 1.0 million m3, down 13%, sawdust totaled 2.8 million m3, up 2%, and unidentified mixtures of industrial residues totaled 0.2 million m3.
Recycled wood consumption was 1.0 million m3, down 6%. Plants also consumed 460 thousand tonnes of wood pellets and briquettes, up 15%.
Including fuelwood burned in small-scale housing, total solid wood fuel consumption in Finland was 27.7 million m3 in 2025.
Solid wood fuel consumption at heat-only and CHP plants was highest in Uusimaa at 2.5 million m3, and the region also recorded the highest forest chip consumption at 1.5 million m3. South Karelia recorded the largest use of forest industry by-products and wood residues at 1.3 million m3.
