This report describes a model for economic analysis of windenergysystems. It concerns an update of a previous published report (ECN/ESC-47; december 1998, which calculates the internal rate of return and the costs of the electricity produced for various systemconfigurations and management options. Calculations have been made for the economics of four types of windturbines (16, 25, 35 and 45 meter rotordiameter). Different types of windfarms (isolated windturbine and 10 or 40 windturbines in line or cluster) are distinguished. The electricity-production, investments- and exploitationcosts are estimated for the years 1991, 1995 and 2000. The economic calculations present results for two forms of management: by private enterprise or public utilities. A sensitivity analysis has been carried out with respect to differences in windregime, electricity prices, investments costs and economic lifetime. The report includes a database on the parameters used.
