An improved model for calculating microeconomic criteria for the effectiveness of investments in energy projects

DOI: 10.33917/mic-3.116.2024.41-68

An improved methodology for calculating microeconomic criteria for the effectiveness of investments in energy projects (and other real sector projects) based on the UNIDO methodology is presented. It allows to determine the analytical relationship between the engineering and economic parameters of power plants (throughout their life cycle) and a set of microeconomic criteria for the effectiveness of investments. Strictly mathematically, the secondary criteria are derived from the definition of the main microeconomic criterion – net present value (NPV): the internal rate of return IRR, the levelized cost of electricity (LCOE) and the discounted payback period DPP.  Numerous examples and graphic illustrations of estimates of individual parameters of investment projects and criteria for investment efficiency are given. A significant difference between the proposed methodology for calculating investment efficiency criteria is the use of average annual values of revenue, operating costs and production, as well as the introduction of special coefficients (φ) reflecting the effect of discounting cash flows at each period of the life cycle (construction, operation and decommissioning).
