In 2016, heating and power plants consumed a total of 19.3 million solid cubic metres of solid fuelwoods, representing an increase of 6 per cent from the previous year, and more than ever before. The total consumption of wood fuels reached an all-time record as well.
In 2016, wood fuels were the most important source of energy in Finland, accounting for 26 per cent of the total energy consumption.
Forest chips used as in the previous year
The most significant solid wood fuel used by heating and power plants was forest chips, the consumption of which increased by one per cent year-on-year to 7.4 million cubic metres.
– The use of forest chips in the combined production of heat and power continued to decrease, shrinking by 6 per cent year-on-year to 4.5 million cubic metres, says Senior Statistician Esa Ylitalo of Natural Resources Institute Finland.
However, the use of forest chips in the generation of heat only increased by 14 per cent, to 2.9 million cubic metres. Together with the forest chips burned in small-scale housing, total consumption reached 8.1 million cubic metres.
Small-sized trees the most significant raw material of forest chips
More than half, or 3.9 million cubic metres, of the forest chips consumed by the plants were manufactured from small-sized trees, i.e. pruned small-diameter stems and unpruned small-sized trees. The second most common source, 2.5 million cubic metres, was logging residues. The use of stumps as raw material for forest chips came to 0.8 million cubic metres, and that of large-sized timber, not suitable for the manufacturing of forest industry products, to 0.3 million cubic metres.
The use of solid by-products for energy generation on the rise
Plants consumed 8 per cent more forest industry by-products and wood residues than in the previous year, a total of 10.9 million cubic metres. The main material used in burning was bark, accounting for almost 70 per cent, or 7.3 million cubic metres, of by-product wood. The use of nearly all types of solid wood fuels increased from the previous year. Proportionally, the greatest increase (+31%) was seen in the consumption of wood pellets and briquettes, and recycled wood (+29%).
The consumption of solid wood fuels was highest in the Central Finland region, while most forest chips were burned in Uusimaa and most forest industry by-products and wood residues in South Karelia.
Record-high amounts of wood used in energy generation in 2016
Based on preliminary data by Statistics Finland, the consumption of wood fuels in energy generation was record-high in 2016, a total of 96 terawatt-hours (TWh). Of the total consumption of wood fuels, solid wood fuels of heating and power plants covered 37 TWh, the combustion of black liquor 41 TWh, the small-scale combustion of wood 17 TWh and other wood fuels 2 TWh. Wood fuels were the most important source of energy, accounting for 26 per cent of the total energy consumption.
