- China has the largest thermal power installed capacity worldwide, which has caused severe greenhouse gas emissions. To reduce the emissions and facilitate the development of energy savings and emission abatement, it is imperative to improve power-generating efficiency. In this paper, the nonparametric weighted Russell directional distance method (WRDDM) was used to evaluate the overall efficiency of thermal power plants in 30 provinces in China. The results show that the efficiency of East and North China is higher than that of Northeast and Southwest China. Furthermore, the correlations between scale, ownership and efficiency are discussed. The nonstate-owned plants with large generation capacity have a higher efficiency than the small and state-owned plants.
