摘要
為達成減碳目標,我國訂定2025年再生能源發電占比達20%之目標。爰而,本研究利用電力規劃模型,評估前述能源轉型政策對發電配比、售電成本、電力排放係數、備用供電容量率等之衝擊。在能源轉型對整體及各縣市之影響方面,本研究將全國投入產出表轉化(細緻)為各縣市投入產出表,以瞭解能源轉型對各縣市實質產值、GDP (國內生產毛額,Gross Domestic Product)以及就業之影響。分析結果顯示,在前述政策情境下,供電穩定及排放目標皆能達成,惟將推升我國電價上漲約43%。在電價上漲之衝擊方面,以六都遭受之衝擊最為顯著,就縣市別而言受影響程度依序為:高雄市(化學業)、臺北市(批發及零售業)、桃園市(電子零組件業)、臺中市(電子零組件業)、新北市(批發及零售業)、臺南市(電力與燃氣供應業)。此外,北部與南部受影響程度明顯不同,主要係產業結構差異所導致。

To reduce carbon dioxide emission, the government set a goal that energy production from renewables shall reach 20% in 2025. Therefore, this paper applies a power planning model to examine the effects of Energy Transition policy on generation mix, costs of power supply, carbon emission factor and reserve margin in 2025. In addition, to investigate the impacts of the said policy on the production value of city/county, GDP and employment, we construct inter-county input-output table aiming at 38 industrial sectors by applying Taiwan input-output table. Model results indicates that the appropriate level of electricity reserve capacity and electricity carbon emission factor will be met. Nevertheless, generation cost may increase by 39% by 2025. Empirical results of inter-county input-output model also indicates that the impacts on county/city in order are as follows: Kaohsiung (Chemical Industry), Taipei (Wholesale and Retail Trade), Taoyuan (Electronic Components), Taichung (Wholesale and Retail Trade), New Taipei (Wholesale and Retail Trade), Tainan (Electricity and Gas Supply). Due to geography industrial structure difference, the impacts between the north and the south Taiwan are also different.
