摘要
隨著2050年淨零碳排的目標在世界各國中逐漸成為共識,能源轉型議題成為了各國的首要之 務。電力產業的主要供應者,由非再生能源為主的大型集中式電廠,須逐漸轉向朝著以再生能源為 主,小型的分散式電源為主。而農牧業通常具有土地面積相對遼闊,建築物相對較大的特性,於是 各國政府也積極推廣「農能共構」的概念,將綠色能源相關之設施系統導入於農牧業之場域中。 本研究以國立中興大學溪心壩農牧場為實證場域,發現超約罰金之情形嚴重,且其每日負載曲 線呈現明顯尖、離峰差距極大的問題。以此為動機,本研究以成本有效性之方式,分別由農牧場經 理人之觀點,以及全社會之觀點,分析農牧場在以下三種模擬情境下之各項成本和收益:情境一、 分析未導入任何綠能設施,更改契約容量之效益;情境二、模擬導入小型綠能設施,分析是否具成 本有效性;情境三、模擬將實證場域打造為淨零能源智慧綠能農牧場(Net-Zero-Energy Smart Green Farm),分析是否具有成本有效性。 研究結果顯示,不論是由全社會或是農牧場經理人之觀點,皆以模擬情境三,當農牧場建置 337瓩太陽能板達成淨零碳排後,選擇不建置任何儲能櫃系統,並將所生產之綠電全部委由售電業 者轉售,相較於其他任何可行方案,更加具有成本效益。此時,農牧場須選擇與台電訂定經常契約 容量119瓩,並採用三段式時間電價,才可獲得最高之效益。

As the goal of net-zero carbon emissions by 2050 has gradually become a consensus among countries around the world, the issue of energy transition has become a top priority for all countries. The main supplier of the power industry, large-scale centralized power plants using non-renewable energy sources, must gradually shift towards renewable energy-based distributed power sources. Agriculture and animal husbandry usually have relatively larger areas or barns. Therefore, governments around the world are promoting the concept of agrivoltaic systems, introducing green energy systems into the field of farms and ranches. In this context, this study focuses on the Hsi Hsin Pa Farm of National Chung Hsing University. It is found that in this empirical field, the peaks exceed the Taipower’s contract capacity almost every month. In addition, two main electricity consumption peaks occurs each day, while the peaks exceed a lot from the trough. Taking this as the motivation, this study adopts the cost-effectiveness analysis (CEA),analyzing the costs and benefits of farms and pastures in the following three simulated scenarios, from both manager’s perspective and societal perspective: in Scenario I, without introduction of any green energy facility, we analyze the benefit of changing the contracted capacity; in Scenario II, we simulated introducing smallscale green energy facilities, and analyze whether it is cost-effective; in Scenario III, we analyze whether it is cost-effective to build this empirical field in to a Net-Zero-Energy smart green farm. The results show that from both societal and managers’ point of views, among all the other alternative strategies, the most cost-effective one happens in Scenario III, in which the farm should build 337 kW of solar panels in order to achieve net zero carbon emissions. The most effective strategy is for the farm to seek for an green-power retailer and sell all the green electricity produced by the PV systems, without building any energy storage systems. At the same time, the farm should set a regular contract capacity of 119 kW, and adopt the three block TOU rate in order to obtain the highest benefit.
