India’s Coalfields Go Green with Repurposing of Decommissioned Mines into Solar Power Hubs

San Francisco

India’s transition from fossil-based power to clean energy has reached a pivotal milestone with a fresh wave of brownfield solar redevelopment that targets the nation’s vast network of abandoned coal mines. A recent industry analysis identifies 63 disused mine sites, together covering more than 500 km² of degraded land, that can be converted into high-yield solar power hubs capable of delivering 27.11 GW of solar potential, roughly 37 percent of India’s current installed capacity. Located primarily in Telangana, Odisha, Madhya Pradesh, and Chhattisgarh, these decommissioned coal mines offer India a double dividend: climate-aligned electricity and fast-tracked land restoration in some of the country’s most industrially scarred regions.

Unlike greenfield developments that often face delays over land acquisition or ecological clearances, mine-to-solar conversions benefit from existing industrial zoning and favourable land ownership and policy clarity. Detailed mapping shows that 96 percent of the selected sites lie within ten kilometres of transmission corridors and 91 percent sit near substations, allowing developers to tap into pre-built grid assets and slash both capital expenditure and lead times. Repurposing coal pits also mitigates methane leakage and environmental hazards typically associated with derelict mines, accelerating India’s commitments under its updated Nationally Determined Contribution while freeing prime agricultural land from competing land-use pressures.

The economic upside is equally compelling. Construction and operation of these solar parks are projected to generate tens of thousands of temporary and permanent jobs, creating a resilient employment bridge for communities historically dependent on coal. By embedding just transition frameworks, covering reskilling initiatives, local procurement, and long-term maintenance contracts, the programme ensures that renewable deployment directly offsets coal-sector job losses and stimulates ancillary industries across civil engineering, logistics, and digital operations.

Technical performance will be further bolstered by a new generation of passive-cooling composites engineered for harsh open-pit environments. A standout solution is a hydrogel overlay formulated from lithium chloride (LiCl) and polyacrylic acid sodium salt (PAAS). LiCl’s unrivalled hygroscopicity draws atmospheric moisture into the gel during cool night-time hours, while the PAAS polymer matrix stores the water until daytime heat triggers evaporative cooling. Field trials show module-rear temperature reductions of up to 14 °C and efficiency gains exceeding 12 percent without any parasitic energy draw. Costing under USD 40 per m², the composite not only boosts generation but also suppresses encapsulant yellowing and solder-joint fatigue, effectively doubling expected module life and lowering levelised cost of electricity across the asset lifecycle.

Demand created by India’s clean energy deployment on degraded land is resonating up and down the supply chain. Manufacturers of corrosion-resistant mounting structures, precision geospatial survey firms, and smart-inverter vendors are lining up to service these brownfield projects. Financial institutions are crafting innovative blended-finance instruments that recognise both the carbon-abatement benefits and the reclamation of contaminated terrain, while insurers report lower long-tail liabilities once environmental monitoring is embedded from day one.
