Abstract

Consideration of the feasibility of building combined power plants (CPP) based on renewable energy sources (RES) and the choice of parameters, type of equipment, layout, and design solutions is based on an assessment of economic efficiency, the indicator of which is the ratio between the required investments and the achieved technical and economic effect. An accurate assessment of economic efficiency is a rather difficult task since it is necessary to take into account a large number of factors, for example, specific features of design solutions, operating conditions of the CPP depending on the requirements of the consumer, the stochastic nature of the manifestation of energy resources, the possible mode of operation of the CPP for the needs of individual consumers and others. An approach based on the minimum cost criteria has been widely used for the economic justification of the objects under construction for a long time. In rigidly centralized economic management, such an approach based on ensuring optimal construction planning played an important role in increasing the scientific validity of economic decisions. It proceeded from the global and national economic goals of economic development. In the conditions of a free market economy, a method of evaluating the effectiveness of taking into account all the main features of it is necessary.
