Investment projects in renewable energy sources represent an increasing economic activity in all countries of the world, especially in the countries of the European Union which had set ambitious plans to increase the share of produced energy from renewable energy sources as their main goals. In this regard, the analysis of the investment power project of the virtual power plant defined in this paper represents one of the possible directions of the solution for further increase of the share of renewable energy sources. Virtual power plants are an additional opportunity to install renewable power plants in power systems in countries / regions that are already burdened by the variable and unpredictable production of various renewable energy sources. The financial analysis of the project was carried out on the basis of the method of capital budgeting and modern concepts of risk management, according to which risks are defined as various statistical functions, ie as a combination of the magnitude of the impact and the probability of its occurrence. The above definition of risk enables the use of Monte Carlo simulation, as any numerical method of statistical simulation, to test the success of any investment project. The financial decision-making methods used to make decisions about the success of an investment in a project virtual plant, namely NPVs and IRRs, are suitable for use in Monte Carlo simulations. The simulation proved the profitability of investing in a virtual power plant using risk management rules as a basis for maximum economic efficiency of the project.
