摘要
非核家園與20%再生能源目標已是我國既定的能源政策,為探討達此政策目標對於我國電力結 構之影響,本研究運用線性規劃分別建立最小成本及最小碳排放電力組合評估模型,評估2025年目 標達成對於電力結構、發電成本、碳排放、天然氣供需及備用容量之影響。考量社會意向對於政策 影響甚劇,特納入民眾非核情境願付電價為限制並設計最小成本與碳排放情境進行政策評估。分析 結果顯示:滿足非核願付電價的最小成本電力組合需由40.48%的燃煤、36.41%的燃氣與20%的再生 能源組成,相對2015年發電成本將增加約17%,碳排放將增加約2%,採用此情境須面對電力碳排 放不減反增,恐抵銷發展再生能源可減碳的良善之意,再生能源滿足政策目標即可。滿足非核願付 電價最小碳排放電力組合需由57.19%的燃氣、20.17%的燃煤與21.59%的再生能源組成,相對2015年 發電成本將增加約33%,碳排放可減少約13%,採用此情境雖可大幅度減少碳排放,但須面對發電 成本大幅增加及天然氣接收站規劃不足的問題,而再生能源須超越政策目標方能達成最小碳排放目 標。另外,兩情境達成政策目標的系統備用容量率皆可大於12%,顯示電力系統仍可維持穩定供電。

The purpose of this paper is to investigate effects of Taiwan’s nuclear-free homeland and renewable energy targets set for 2025 were fulfilled to power portfolio, generation cost, carbon emission, supply and demand of natural gas and reserve margin. This paper employed the linear programming to establish respectively the least-cost and least-carbon emission power portfolio assessment models. Social intentions always influence policies greatly. Therefore, Taiwan’s public willingness to pay for electricity which supports nuclear-free homeland was considered. Least-cost power portfolio which satisfies public willingness to pay is composed of 40.48% coal-fired, 36.41% gas-fired and 20% renewable energy. Generation cost and carbon emission increases respectively 17% and 2% compared to 2015. Least-carbon emission portfolio which satisfies public willingness to pay is composed of 57.19% gas-fired, 21.59% renewable energy and 20.17% coal-fired. Generation cost increases 33% but carbon emission can be reduced13% compared to 2015. According to assessment, electricity reserve rates are more than 12% and thus power system can still keep stable power supply for both power portfolios.
