When demand is down, utilities end up reducing offtake from costlier coal plants, and buy more from other sources such as hydro, renewables and nuclear, said Sambitosh Mohapatra, partner for power and utilities at Pricewater-houseCoopers India.
Power generation from coal, the most polluting fossil fuel, slumped 11 per cent from a year earlier in November. Output in the year to November fell 2.4 per cent, the first ever drop for the 11-month period.
India has a coal-fired generation capacity of almost 198 gigawatts, which accounts for about 54 per cent of its installed generation capacity. That share has reduced over the past years and is set to come down further as the country adds more clean power to deal with air pollution and meet its climate goals. India’s coal fleet used barely 51.4 per cent of its capacity in November, compared with 60.5 per cent a year earlier, Central Electricity Authority data showed.
