摘要
政府(2011)發佈新能源政策,確立國家逐步減核,邁向非核家園願景。然而,調降核能發電配比,將由何種能源(如煤炭、天然氣或再生能源)取代其發電缺口?不同替代能源,將影響發電成本及CO2減量目標等,是影響政府選擇替代方案的重要參考。本研究引入選擇價值方法(option value method),並納入碳價不確定性因子,評估三種替代方案(分別為燃煤機組加裝CCS、燃氣機組及混合方案) 彌補減核之發電缺口的政策選擇價值。評估結果發現:(1)在2020年減核達總發電量6%後,即不宜再繼續擴大減核至12%;(2) 燃煤機組加裝CCS相較擴大天然氣機組更適宜作為減核之替代方案。

The New Energy Policy was announced in 2011, by the Taiwanese’s government. Under this new energy policy, the nuclear power share will be gradually phased out to approach unclear free country. However, what’s the best alternative energy to make up the electricity generation gap, for the nuclear power to be phased out? This is a key issue to launch the New Energy Policy in the future. This paper uses a real option pricing method to estimate the value of low carbon electric technologies, as well as carbon capture and storage (CCS), in the face of uncertain carbon prices. This is to make sure the new energy policy is the optimum for Taiwan. The real option value analysis shows that 6% nuclear power share reduction is the highest option value by 2020. Furthermore, expanding the nuclear power share reduction by 12% is unsatisfactory result. In addition, the coal power plan is a better alternative one than natural gas power plan with CCS. This is because of the impact of lower electricity prices and an almost indifferent environmental benefit.
