India: NTPC targets 149 GW by 2032 as thermal and renewables expand together

• Renewables targeted at 60 GW, but thermal rises to 83.6 GW
• INR 16.86 lakh crore plan targets generation, storage and nuclear

NTPC plans to increase its generation capacity from around 91 GW currently to 149 GW by 2032 and 244 GW by 2037, backed by cumulative capital expenditure of INR 16.86 lakh crore across thermal, renewable, hydro, pumped storage, battery storage, mining and nuclear projects.

The expansion reflects a broader shift in India’s electricity transition. Renewable energy will account for most new capacity additions, but thermal generation will continue to expand as rising electricity demand increases the need for reliable, round-the-clock supply. Batteries, pumped storage and nuclear power are expected to play a larger role over time, but coal-fired generation remains central to meeting demand through the current decade.

Thermal generation remains the foundation of NTPC’s portfolio

Coal continues to dominate NTPC’s generation fleet. Thermal capacity, including gas-based plants, exceeds 73 GW, accounting for almost three-quarters of the company’s installed capacity, while solar and wind together contribute around 12.45 GW.

NTPC is already executing a substantial expansion programme, with more than 35 GW of generation capacity under construction. The pipeline includes thermal projects at Darlipali-II, Gadarwara-II, Lara-II and III, Nabinagar-II, Singrauli-III, Sipat-III, Talcher-III, Telangana Stage-II, Meja-II and Patratu, alongside a growing portfolio of renewable projects.

The construction pipeline shows that thermal generation continues to expand alongside renewable capacity rather than being replaced by it. NTPC’s capacity roadmap to 2032 reinforces that trend.

Renewable capacity is expected to increase nearly five-fold, from around 12.45 GW currently to 60 GW by 2032, however, thermal capacity is also projected to rise from around 73.9 GW to 83.6 GW over the same period. Coal’s share of the generation portfolio will therefore decline as renewable capacity grows, but its absolute capacity will continue increasing. The distinction is significant for India’s coal market. Faster renewable deployment does not necessarily reduce thermal capacity where electricity demand continues to expand.

Electricity demand continues to require firm generation

India’s power system increasingly relies on multiple technologies to balance rising electricity demand. Solar generation supplies large volumes of low-cost electricity during daylight hours, but dispatchable capacity remains essential during evenings, overnight periods and episodes of weak renewable output.

Hydropower can provide part of that flexibility, although generation varies with rainfall and reservoir levels. Gas-fired power remains relatively expensive for sustained baseload operation. Coal therefore continues to provide the firm generation required to maintain grid stability while renewable capacity expands.

Storage and nuclear become the next phase of the transition

NTPC plans to develop 22 GWh of battery energy storage by 2032, alongside pumped-storage projects, while evaluating a substantially larger long-term pumped hydro portfolio.Greater storage capacity will allow surplus renewable generation to be shifted from periods of high solar output to evening demand peaks. Until storage reaches sufficient scale, thermal generation will continue providing much of the balancing capacity.

Beyond 2032, nuclear power forms the next stage of NTPC’s expansion strategy. The company has set a target of developing around 30 GW of nuclear capacity by 2047, contributing towards India’s national ambition of 100 GW. Its immediate programme includes the 2.8 GW Mahi Banswara project in Rajasthan, while additional locations are under evaluation.

Outlook

NTPC’s expansion plans indicate that India’s electricity transition is being shaped by rising demand rather than fuel substitution alone.

Renewables will account for most new capacity additions through 2032, but thermal capacity is also expected to increase as the power system continues to require firm generation alongside variable renewable output. Batteries, pumped storage and nuclear power are expected to assume a larger balancing role over time, but their expansion will be gradual.

For coal markets, the implications are clear. Coal’s share of NTPC’s portfolio will continue to decline as renewable capacity expands, but its absolute thermal capacity is still expected to increase through the current decade, reinforcing coal’s role in supporting India’s growing electricity demand while the broader transition continues.
