India nuclear capacity target 100 GW by 2047: SHANTI Act, SMRs, and project progress

India is pushing to grow its nuclear power capacity from the current 8.8 GW to 100 GW by 2047. The article covers the status of ongoing reactor construction, including five PHWRs totaling 3,500 MW and four PWRs adding 4,000 MW, with commissioning expected by 2031-32. NTPC plans to develop around 30 GW of nuclear capacity across 14 states, and the newly passed SHANTI Act opens the door for private sector participation in building, owning, and operating plants. Emerging technologies like small modular reactors (SMRs) are also discussed as a way to expand nuclear applications beyond baseload power. The Tarapur plant has resumed operation after refurbishment. This is a concrete look at how India intends to use nuclear as a round-the-clock low-carbon complement to renewables, though timelines and regulatory details will determine whether the 100 GW target is realistic.
