The article discusses the possibility of ensuring sustainable energy supply for remote forest terminals through the use of logging residues as an energy source. A technological chain has been proposed for converting the energy of logging residues into electrical energy, including a chipper, a steam generator and a steam screw machine. To justify the system of machines for remote forest terminals, a mathematical model was developed, implemented in the MS Excel software package. This model helps determine the optimal machine system for powering timber terminals, taking into account various input parameters such as volume of roundwood harvested, skidding distance, percentage of roundwood sawn and lumber drying. Based on these parameters, the model optimizes the choice of technological equipment used to achieve maximum productivity of the timber terminal for a certain volume of fuel chips produced from logging residues. The developed model revealed limitations in the application of the proposed technology, primarily associated with the minimum volume of roundwood harvested per shift. The data obtained showed that to ensure efficient operation of the timber terminal, a minimum volume of roundwood harvesting is required, at least 274 m3 per shift. In addition, the model allows you to reduce peak energy load due to the optimal distribution of technological processes, such as chip production, sawing round wood and drying lumber during the shift. The system also has a database of equipment and machinery into which new units can be added. Based on this information, the system proposes the optimal combination of technical equipment to improve the efficiency of the timber terminal. In addition, this model addresses the problem of excess accumulation of logging residues, increasing their use for electricity production and creating environmentally sustainable energy solutions.
