The pricing of thermal energy is an important component of the efficient operation of the heat supply system. The article deals with the calculation of the cost of heat for consumers and producers of heat as based on the optimization problem of operation modes of the heat supply system with its further reduction to the conditions of optimality. The latter is to be achieved on the basis of the Lagrange function, with undetermined Lagrange multipliers obtained in the calculation process to be interpreted as nodal (marginal) prices of heat. This approach allows one to determine the pricing at each node. Based on the calculation of nodal prices of heat we determine the cost of heat transportation. Backed by the methodological tools developed, we have performed a demonstration of the calculation of nodal prices of heat and developed an algorithm for calculation of nodal prices of heat generation and consumption and overall technical and economic performance indicators of the heat supply system.
