- 摘要
- 為因應地球暖化及穩定能源供給，政府長期以來推動能源多元化，並發展包括核能在內的低碳能源使用，惟因福島事件後，政府頒布之新能源政策以「穩健減核」為推動主軸，並大幅度提高再生能源發展目標。因此，本文目的在於評估各項能源成本變動下電力配比的可能情境，透過可考慮基、中、尖載及輔助電源特色之經濟計量模型，研析在成本最小化條件下，我國各類發電技術之最適配比，同時考量不同碳稅課徵稅額時最適配比影響和變化。本文發現，依成本極小化原則所估計之最適配比，核能發電比重在未課徵碳稅情境應占發電系統13%以上，若為課徵碳稅情境時，隨著稅額越高，則核能最適配比將進一步增加。以碳稅稅額40美元/噸CO2為例，核能最適配比將近16%，顯示核能仍扮演重要的電力供應來源，而不宜完全排除核能，故能源政策制訂可考慮將核四商轉或既有核能機組全部／部分延役作為選項。其次，再生能源最適配比在未課徵碳稅情境下約為6.40%，低於目前規劃的2025年再生能源發展目標配比(11.7%)，惟隨著稅額越高，再生能源最適配比亦將進一步增加到8.16%，顯示欲達到規劃之再生能源發展目標，在能源政策上可考量搭配碳稅稅制，將各類發電技術的碳排放成本合併考量，作為支持達到再生能源發電目標之方式。

- In order to response the issue of global warming and stable energy supply, Taiwanese government has been continuously promoting the diversification of energy and developing the low-carbon energy, including nuclear power. However, after Fukushima Nuclear accident, government issued the new energy policy to settle the principal of a nuclear-free homeland and enhance the renewable energy development plan. Hence, the purpose of the study is to build an econometric model that considers base load, medium load, peak load and auxiliary power under the condition of minimum cost and to evaluate the optimal electricity allocation. We also calculate the optimal electricity allocation in different carbon tax scenarios. The results show that the optimal electricity allocation of nuclear power in Taiwan is 13% under the condition of minimum cost (exclusive of carbon tax). In the scenario of levying carbon tax, the optimal electricity allocation of nuclear power will rise. For example, the optimal electricity allocation of nuclear power is almost 16% when carbon tax rate is $40/ton CO2. The policy implication is that the nuclear power is still one important resource of power supply and we can consider that the Lungmen nuclear power plant is commercially operated or the existed three nuclear plants extend the lifespan. Besides, the optimal electricity allocation of renewable energy is 6.4% in the scenario excluding carbon tax. It is lower than the renewable energy development plan (11.7%) in 2025. However, the optimal electricity allocation of renewable energy will increase with higher carbon tax rate. If the carbon tax rate is $40/ton CO2, the optimal electricity allocation of renewable energy will be 8.16%. It shows that to achieve the renewable energy development goal, we could collocate with levying carbon tax and take the cost of carbon emission in different power supply source into consideration. That will be one of the measures that supporting for renewable energy.
