Conditions for the Development of Wind Energy for Individual Consumers: A Case Study in Poland

Abstract

This article presents the economic viability of using 10 m wind turbines in households with financial support from the government. The aim of this study was to indicate whether and how state subsidies affect the efficiency and estimated payback periods of wind energy investments for individual households. The research conducted thus far has focused on the analysis of effectiveness, feasibility, and economic profitability, but it has not taken into account government support for the investment readiness of households, which constitutes a research gap in the literature and economic practice. In addition, this study analyzed a new program that is scheduled to come into force this year. The analysis used the Homer Pro software (ver. x64) module, and simulations were performed for three locations in Poland. Due to differences in the location of wind zones, as well as the location of two locations on the Baltic Sea, an additional factor characterizing the studied voivodeships was introduced. Government support may therefore constitute a mechanism for correcting the geographical location and local wind potential. It has been shown that financial support significantly accelerates the payback period, even in locations with weaker wind potential. Complementary and substitutive possibilities for renewable energy sources, such as sun and wind, were indicated. The conclusions from this research can be used by decision makers and individual households to take advantage of government support to shorten the return on investment in wind energy and the validity of this support.
