| Abstract: | The aim of this article is to identify the relative importance of technical and economic variables in the financial feasibility of repowering wind farm projects. A financial valuation model is developed. We carry out a sensitivity analysis with several variables considered to be key in the repowering decision. The most relevant technical variable is the increase in production efficiency and the most relevant economic variable is the capital expenditures in new equipment. Furthermore, the decision to repower critically depends upon the level of support being provided. The repowering project would not be feasible in the absence of support. |
