India must integrate renewable and coal-based power sectors for successful energy transition: CSE study
The study, Flex to Fix: Deciphering India's Coal Flexibilisation Challenge for RE Integration, said coal power flexibilisation could help create an additional 18-34 GW of renewable energy space and reduce power-sector emissions by 7.66-8.37 per cent, equivalent to 92-101 million tonnes of carbon dioxide annually. CSE released the report at a national dialogue on coal flexibilisation and reforms in thermal power purchase agreements (PPAs), attended by representatives of the Central Electricity Authority, Central Electricity Regulatory Commission, GRID-India, BHEL, NTPC and Torrent Power, besides experts from think tanks, civil society and academia. CSE Director General Sunita Narain said India's power sector must work towards greater grid flexibility as renewable energy expands. "We are not talking about renewable vs coal here. We are talking about renewable and coal, and about how to integrate the two. The task is not to replace coal, but to displace it," she said. The study noted that India reached 50 per cent non-fossil-based installed power capacity in November 2025, five years ahead of its original 2030 target. However, rapid growth in renewable energy, particularly solar power, has altered the demandsupply balance and increased operational stress on conventional generation.
