India’s solar energy output growth slowed in September, a Reuters analysis of government data showed, at a time when coal-fired utilities are facing a shortage of a fuel that accounts for more than 70% of the country’s power generation.
Growth in solar energy is critical this year as half of India’s 135 coal-fired power plants have fuel stocks of less than three days. India expects the coal shortage to last for up to six months.
State-run Coal India, which accounts for over 80% of India’s coal output, saw production grow at the slowest rate in six months and supplies at the slowest rate in seven months during September as rain affected output in key mining regions.
Solar energy generation growth slowed to 24.7% year-on-year in September from 41% in August, an analysis of federal grid regulator POSOCO’s daily load despatch data showed.
Other key sources of electricity generation also fell in September, the data showed, with hydro declining 5% and gas-fired power falling 31.6% compared with the previous year.
