Introduction For years there have been significant efforts to implement data envelopment analysis DEA for meas- uring the relative efficiency of similar units Charnes et al. 1978 Banker et al. 1984 . DEA has been commonly applied when input output are not measurable by applying financial figures. For example in educational systems one may be interested in promoting schools with students who reach academic excellence. In electricity industry there are many units in the world which are reporting lost in their statements due to various reasons and any additional budgets must be based on non-financial numbers such as the number customers covered the volume of electricity transmitted etc. Fig. 1 shows a sample of different factors influencing on efficiency .
