國營發電部門之營運績效常受一些如能源政策、調度因素等非可控因素所影響，這些非可控因素大多是複雜到無法具體化，為求投入及產出的單純化，本研究為僅針對裝置容量、人力、運維費三種投入要素及淨發電量為產出要素進行資料包絡分析法的結果所下的結論，來探討台灣發電廠目前之經營績效，並針對差額變數分析結果提出各部門實際問題所在。
本研究主要結論有：
一、由整體18座發電廠為分析對象得知平均相對效率最佳的5座發電廠為台中火力、核三、核二、核一及東部水力發電廠；最差的5 座發電廠為大觀水力、明潭水力、大林火力、南部火力及卓蘭水力發電廠。針對18座發電廠績效之提昇可從差額變數分析結果進行改善，應先從8個有閒置裝置容量、3個有閒置人員及7個運維費過高的發電廠進行檢討。
二、由水力7座發電廠為分析對象得知平均相對效率較佳之電廠為明潭發電廠；而相對效率較差為卓蘭發電廠。就提高水力發電部門之經營績效部份，應先從4個有閒置裝置容量、3個有閒置人員及2個運維費過高的發電廠進行檢討。
三、由核能3座發電廠為分析對象得知其相對效率值以核三發電廠最佳，核二發電廠最差。就提高核能發電部門之經營績效部份，應先從1個有閒置人員及2個運維費過高的發電廠進行檢討。
四、由8座火力發電廠為分析對象得知相對效率值以台中發電廠最佳；而相對效率較差者為大林發電廠。就提高火力發電部門之經營績效部份，應先從4個有閒置裝置容量、4個有閒置人員及6個運維費過高的發電廠進行檢討。
五、由以上四類分析可知台電發電廠之技術效率均大於總效率，表示較差之總效率均來自規模效率，意即發電廠對於投入項目均能有效使用；但其投入與產出之比例不適當造成規模效率不佳；故台電發電廠總效率不佳應從規模效率著手。

The achievements of operation in Taiwan Power Company, a state-run power supply enterprise, affect by the non-controllable factor such as energy policy and dispatcher factor and so on. The conclusion based on simplification for input and output because that these factors too complicated to concreted. This research uses data envelopment analysis (DEA) to evaluate relative efficiencies of power plants in Taiwan Power Company by involving variables of the capacity, manpower, the cost of operation and maintenance, net power output, through relevant documents. The slack variable analysis show that where these shortcomings are.
This main conclusions of this study are summarized as follows:
The empirical results indicate that the best average relative efficiency of 5 power plants are the TaiChung thermal power plant, 3rd nuclear power plant, 2nd nuclear power plant, 1st nuclear power plant and the Eastern hydropower plant. The worst 5 power plants are The Takuan hydropower plant, Mingtan hydropower plant, DaLin thermal power plant, Nan-Pu thermal power plant and the Jhuolan hydropower plant.
The slack variable vnalysis show that there are the eight idle installed capacity, three idle personnel and seven over cost of operation and maintenance of the power plant to carry on the self-criticism.
The good average relative efficiency power plant among seven hydropower plants are Mingtan; But the bad relative efficiency is Jhuolan power plant. Enhances management achievements of the hydropower plant department, should first have the four idle installed capacity, three idle personnel and two over cost of operation and maintenance of the power plant to carry on the self-criticism.
By the three nuclear power plant for the analysis object knew its relative efficiency to be best by the 3rd site, the 2nd site is the worst. Enhances management achievements of the nuclear power plant, should first have the one idle personnel and two over cost of operation and maintenance of the power plant to carry on the self-criticism.
For analyzing the object knowing relative efficiency by eight thermal power plants, the best is the Taichung power plant; but relative bad efficiency is the DaLin power plant. Enhances management achievements part the thermal power plant should first have the four idle installed capacity, four idle personnel and six over cost of operation and maintenance of the power plant to carry on the self-criticism.
From four type of analyses, the technical efficiency is bigger than overall efficiency in Taipower company. Because the input efficiency over the output efficiency ratio is inadequate, therefore, we may promote overall efficiency by the way of the improvement of scale efficiency.
