India's geothermal energy sector, with a potential of 10,600 MW across 381 sites, is gaining momentum following the 2025 National Geothermal Energy Policy. ONGC is spearheading efforts with its Puga Valley project, while SCCL operates the only functional geothermal power plant.

Major players like Thermax, Greenko Group, and ReNew Power are exploring opportunities. The Ministry of New and Renewable Energy is key in policy and regulatory support, facilitating research funding and inter-agency collaboration. Challenges include high costs and limited expertise, but international partnerships may accelerate growth.
