電力能源為一個國家在發展上的基本動力，近年來台電公司內部的相關發電量數據顯示，目前國家經濟發展正值用電劇增之際，從民國98年至99年在售電量方面由179,159百萬度增加至193,313百萬度，成長幅度7.9%，但因國內環保意識抬頭以及核電爭議，台電目前之發電規劃受到莫大影響，因此，本研究的目的是希望透過對台電主要的火力電廠進行經營績效分析，給予實質建議，希望對台電未來之能源發展規劃有所幫助，並試圖解答目前台電公司在火力發電上績效提升的差異點為何，以及是否還有改善的空間，未來是否能夠達到環保與發電量兼具之問題。在研究方法上，本研究運用DEA法不可切割模式，加入考量不良產出物部分，衡量從民國95年至99年台電火力發電部門的投入與產出數據。評估台電火力發電部門各火力電廠各項營運效率，利用總效率分析部分給予各火力電廠在總體營運改善上建議，藉由差額分析與敏感度分析提供各火力電廠在改善資源配置以及關鍵的改善效率投入產出因素上給予客觀與實質的建議。本研究在運用DEA法非意欲產出模式中的不可切割模式上，在台電火力發電部門各火力發電單位中，整體效率以興達汽力機組、林口電廠以及台中電廠相對表現較佳，以大潭電廠0.423表現最差，在效率相關參考集合分析當中，以林口電廠被參考次數22次為最多；在差額變數分析中，興達汽力機組、林口電廠與台中電廠表現最佳，設備利用與資源配置均無浪費或閒置情形，以大潭電廠表現最差，平均管理效率僅有0.425；在敏感度分析方面，產出項淨發電量為多數發電單位敏感度高之項目，其次是營運費用與設備容量因素。本研究在實質層面上之貢獻，透過加入不良產出物的考量因素，可以更客觀的資料數據進行分析，提供台電火力發電部門在面對現今之嚴苛環境下，進行更適切的營運規劃與資源配適，在新能源開發的過渡時期，能夠更穩健無虞的提供國家發展所需之能源，使用電量日漸提升的今日能夠持續獲得良好的用電品質，並且穩定國家日後的經濟發展。 The electrical energy is the basic motive power of the development of a country. Recently, the related data of electricity generation within the Taiwan Power Company (Taipower) shows that the national economic development is on the occasion of a surging need of electricity. From 2009 to 2010, the electricity sales increased from 179.159 billion to 193.313 billion kWh, at a growth rate of 7.9%. However, due to the rise of domestic environmental awareness as well as the nuclear dispute, the current electricity generation planning of Taipower is greatly influenced. Therefore, the purpose of this study aimed to provide Taipower with the substantial suggestions through conducting the operational performance analysis of its thermal power plants in hope of subserving Taipower’s future energy development plan and tried to answer the different points of Taipower’s improvement on the thermal power achievement. Also, it tried to see if there’s anything left to be desire and if it can achieve both environmental protection and power generation problems.As for the research methods, this study used DEA non-separable mode, adding the consideration of the defective products, to measure the input and output data of Taipower’s thermal power department from 2006 to 2010. It assessed the operational efficiency of the thermal power plants in the thermal power department, and used the overall efficiency analysis to partly give the suggestions to every thermal power plant for its overall operational improvement. Through using balance analysis and sensitivity analysis, it provided the objective and substantial suggestions to every thermal power plant on improving the resource allocation and key efficiency input and output factors.In this study, I used the non-separable mode in the DEA non-desirable output mode. In each of the thermal power sector in the thermal power department of Taipower, the overall efficiency of relatively better performance is Xingda steam power unit, LinKou power plants and Taichung thermal power plants, and the Datam power plant, whose number is 0.423, is the worst. Within the analysis of efficiency related referential set, the reference number of Linkou is 22 times, and it is the maximum. In the analysis of balance variable, the Xingda steam power unit, LinKou power plants and Taichung thermal power plants perform well, and there’s no waste or idling in the equipment utilization and resources allocation. The Datam power plant acts the worst, with the average management efficiency of 0.425. As for the sensitivity analysis, the output of the net power generation capacity is the high sensitivity item among the majority of the power generation units, followed by the factors of operational costs and equipment capacity.The substantial contribution of this study is to conduct the data analysis based on more objective information through adding the consideration of defective products factors, and make the thermal power department of Taipower conduct a more appropriate operational planning and resources allocation in face of the harsh environment. It can provide the country with the needed resources under her development in the transitional period of new energy development; also, it makes the country to keep obtaining better electricity quality under the steadily growing use of electricity nowadays, and stabilizes the country’s future economic development. |
