The rate of growth of generation capacities in public sector is in line with the additions to the installed capacity. During the last 50 years the thermal generation registered a spectacular growth. However, the growth in hydro generation was very poor. Also on the nuclear front, 10 Nuclear power plants accounted for only around 2% of total utility generation.Owing to the decline in hydro development and prevailing peak power deficits, coal-fired thermal power units are often used for meeting peak loads. Poor performance of India's existing generating units has been a principal cause of worry. The average plant load factor (PLF) of thermal power stations in India is less than 60%, but varies considerably across the regions. In contrast, hydro power stations have far better track record due to the fact that their performance relies largely on water flow.The sector wise and region wise generating capacities are given in the table 1 below:
