Even as the government continues its push for renewables, coal-fired power is expected to remain the main source of energy for the next decade or so, Power and New and Renewable Energy Minister R.K. Singh said on Tuesday.

The capacity of coal based generation would increase from the current about 195 gigawatt (GW) to 238 GW by March, 2027.

"Accordingly, the total coal requirement would increase from 698 MT for 2019-20 to 877 MT during 2026-27," Singh said in a written reply to the Rajya Sabha.

As there is a already shortage in coal supply, the government needs to raise production to meet the needs of thermal power plants.

"Besides meeting the present deficit in coal supply to power sector, Coal India Limited (CIL) may enhance its production to meet the growing requirement of the power sector," the Minister said.

As per the National Electricity Plan (2018), the share of electricity generated from coal-based power plants is likely to be 64 per cent at the end of 2021-22. Its share is projected to further come down to 58 per cent by 2026-27 from the current level of 72 per cent.

"The reduction of share of coal-based generation in the total generation over the period would be mainly due to addition of renewable energy," the Power Minister said.

The government has taken a slew of measures to expand installed capacity through renewable energy sources. They include waiver of inter-state transmission system (ISTS) charges and losses for inter-state sale of solar and wind power for projects to be commissioned up to March 2022.
