Abstract

The present paper attempts to measure the technical efficiency of 75 coal fired public sector thermal power plants in India for the period 2014-15 to 2017-18 using non parametric approach,  Data Envelope Analysis (DEA) with a single output i.e. Power generation and five inputs viz. installed capacity, planned maintenance, forced outages, auxiliary power consumption and specific coal consumption.  The mean technical efficiency for the period under study varied from 66.1% to 100% under CRS, VRS and Scale efficiency.  The technical efficiency of Central Government operated power plants far exceeded compared to those plants operated by the respective State Governments.  The mean technical efficiency has remained more or less same with minor fluctuations but the number of thermal power plants with technical efficiency above the mean technical efficiency shows an increasing trend.
