Uses data envelopment analysis to evaluate relative efficiencies of power plants in Taiwan Power Company

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.
