Abstract The heat supply problem of the city of Baikalsk isconsidered. The most environmentally friendly solution of this problem is using of the timber, which was felled during forest sanitation outside the Anchuk village. Environmental friendliness and other advantages of the biofuel are the main reason of using this type of heat source. This article presents comparative analysis of the production and delivery costs of the fuel wood chips and pellets for Baikalsk. Pressed fuel wood chips and chips with standard bulk density are considered. The levelized cost of heat, unit cost and capital costs are used as indicators of the economic efficiency of pellets and fuel wood chips. According to the results of all three economic indicators, pressed fuel chips proved to be most effective type of heat source than others. Unit cost and LCOH are roughly the same for pellets and for pressed fuel chips. However, the capital costs of production and transportation of the pellets are almost 50% higher than for pressed chips. Thereby, it is preferable to choose pressed fuel wood chips burning for economic reasons of the reducing transportation expenses.
