Abstract
From a developer’s point of view the construction of a wind farm in Poland is an investment project assessed in terms of economic efficiency. This paper discusses the selection of methods to be used for the assessment of such investments: it proposes to consider wind farm construction as an option and price it using models developed for the financial market. The purpose of the paper is to present a practical application of the option pricing method to the assessment of wind farm construction efficiency, in particular to compare the option and discount methods. Calculations are based with the example of an actual wind farm completed by one of the authors. The values of the project are different depending on the chosen method of estimation. The pricing carried out using the options method will lend legitimacy to the DCF result or suggest the verification of its correctness and review of the assumptions made. In both cases the application of the options method will have an advantageous impact on the investment decision.
