India may need additional up to 28GW of coal-fired power generation capacity by 2032 apart from the 25GW thermal projects that are under construction, said a report by advisory body Central Electricity Authority (CEA). “It is seen that apart from under construction coal-based capacity of 25GW, the additional coal-based capacity required till 2031-32 may vary from 17 GW to around 28 GW,” CEA said in a draft national electricity plan.
