Investment Profitability Analysis for Wind Power Project in Taiwan

摘要

In this paper, fuzzy financial evaluation models are derived to analysis investment financial profitability and possibility for wind power generation project in Penghu, Taiwan. The financial subsidy and feed-in tariff (FIT) are two effective market mechanisms to promote wind power development in Taiwan. The performances of the proposed fuzzy profit models are verified by considering their application to a simulation case. The study shows the fuzzy financial indexes of the simulated 2,400 kW wind power project may little uneconomic possibility, with negative net present value, with benefit cost ratio smaller than 1, and with payback years longer than its life span, in both two scenarios. The FIT rates should be revised to match wind power current market to give more attractiveness for potential investors. The studied results are also consistent with those provided by the conventional crisp models, and provide readily implemented possibility analysis tools for use in the arena of uncertain finance.
