A new report puts India’s geothermal electricity potential at 28 times the world’s current total output.
On April 25, 2026, peak electricity demand in India jumped nearly 20 GW in two hours to 256 GW. An unseasonably early heat surge, compounding rising data center loads, compressed a grid already stretched thin. It will not be the last time.
A new report released this week by Project InnerSpace and the Council on Energy, Environment and Water makes the case that India has a largely untapped resource capable of addressing exactly this kind of structural pressure: geothermal energy.
The numbers in the report are difficult to absorb at first reading. India holds technical potential for 11,000 GW of industrial heat, more than 1,500 GW of cooling capacity, and 450 GW of electricity generation. That electricity figure roughly equals India’s entire current installed generation capacity from all sources combined. It also represents approximately 28 times the world’s total deployed geothermal capacity of 16 GW.
The Real Opportunity Is Not Electricity
The electricity number grabs attention. The more immediately deployable opportunity is industrial heat and cooling, and that is where the report focuses its near-term case.
India’s industrial sector is heavily fuel-based. Chemical plants, textile facilities, pharmaceutical manufacturers, and food processors all run on process heat that is difficult to electrify with intermittent renewables. Geothermal provides continuous, temperature-stable heat directly. Aarti Industries, one of India’s largest specialty chemical companies, is already exploring geothermal integration at its Jhagadia facility in Gujarat, identified in the report as one of the country’s most commercially compelling development sites.
The cooling case is equally compelling. Geothermal cooling systems can cut electricity use by 30 to 40% relative to conventional air conditioning. In a country where cooling demand is rising fast and data centers are projected to consume 13.56 GW by 2031, shifting cooling load off the grid is not an abstract efficiency gain. It is grid stability infrastructure.
Gujarat’s Cambay Basin and surrounding industrial zones concentrate geothermal resources alongside petrochemical, textile, and pharmaceutical manufacturing clusters with substantial heat demand. Dholera, emerging as a major data center corridor, sits within the same geography. The resource and the demand are in the same place.
What Changed to Make This Viable
India explored geothermal resources decades ago and largely stopped. High exploration risk, uncertain drilling returns, and the absence of policy frameworks killed early momentum.
Three things have shifted. Advances in drilling technology and subsurface data interpretation have reduced exploration uncertainty. India’s National Policy on Geothermal Energy, adopted by the Ministry of New and Renewable Energy in 2025, created the country’s first dedicated regulatory framework, with fiscal incentives, single-window clearances, and provisions for oil and gas companies to redeploy existing drilling capabilities. And the grid crisis has made the case for baseload, weather-independent clean energy sources considerably more urgent.
Reliance Industries is exploring a 50 MW enhanced geothermal system in Madhya Pradesh. Oil India is assessing a 20 to 25 MW plant in Arunachal Pradesh. A 25 MW pilot at Tatapani in Chhattisgarh is at the planning stage. India has no major operational geothermal plants yet, but the pipeline is moving.
Technical Potential Is Not a Deployment Forecast
The report is careful to distinguish technical potential from economic viability or near-term deployment. The 11,000 GW industrial heat figure represents what exists in the geology, not what will be built. Drilling costs, financing structures, permitting timelines, and transmission infrastructure all determine how much of that potential ever reaches commercial operation.
The comparison to solar tells the story. India’s solar technical potential was also enormous on paper for decades before the policy environment, financing models, and manufacturing costs aligned to unlock it. Geothermal is earlier on that curve. The report is making the argument that the curve has started to bend.
The priority targets are clear: direct-use heat for industry, cooling for data centers and cities, and electricity in regions with the highest-temperature resources. Even partial deployment across those three applications would meaningfully reduce grid stress in the world’s most populous country, which is adding energy demand faster than almost any other major economy.
