SECL Explores Joint Ventures with Chhattisgarh Government in Floating Solar and Coal Gasification
South Eastern Coalfields Limited (SECL), a subsidiary of Coal India Limited and the operator of some of India's largest coal mines, is exploring joint ventures (JVs) with the Chhattisgarh state government in two areas: floating solar power and coal gasification.
SECL's Chairman and Managing Director disclosed in February 2026 that the company has identified a coal gasification project for acquisition and plans to set up 700 MW of solar capacity, including floating solar on mine water bodies.
The Chhattisgarh government is keen to co-develop projects in critical minerals alongside the floating solar and gasification initiatives.
The diversification drive is part of SECL's stated goal to achieve net-zero status by 2030, requiring substantial renewable energy generation to offset coal-mining operations.
SECL operates India's largest coal mine complex at Gevra in Chhattisgarh, which is on track to become the world's largest coal mine by output by 2027.
These announcements signal a broader pattern among Coal India subsidiaries of diversifying into clean energy while maintaining their core coal production business.
Coal Gasification: Technology, Policy, and India's National Mission
Coal gasification is a thermochemical process that converts coal into syngas (synthesis gas — a mixture of carbon monoxide, hydrogen, carbon dioxide, and methane). Syngas can be used for electricity generation, production of chemicals (methanol, ammonia, urea), liquid fuels, and hydrogen. For India, which has vast coal reserves but high import dependence on petroleum and fertiliser feedstocks, coal gasification offers a domestic energy security route.
SECL's coal gasification JV with Chhattisgarh aligns directly with the National Coal Gasification Mission's 100 MT target — a state government co-investment structure that shares capital risk while leveraging SECL's mine infrastructure and Chhattisgarh's coal-bearing geology.
Floating Solar: Technology, Potential, and Policy Framework
Floating photovoltaic (FPV) or floating solar refers to the installation of solar panels on water bodies — reservoirs, lakes, mine pits, irrigation tanks, and ponds — rather than on land. For a coal mining company like SECL, which operates large open-cast mines with extensive water bodies (mine pits filled with water), floating solar is a natural fit for on-site renewable energy generation.
Key Details
- India's total floating solar capacity commissioned: approximately 700 MW (as of late 2025), against a technical potential of ~100 GW (TERI 2025 assessment — 55 GW from reservoirs/barrages, 37 GW from tanks/ponds).
- India's 2030 floating solar target: 10 GW — would save over 300,000 acres of land while generating clean power for approximately 10 million homes.
- MNRE (Ministry of New and Renewable Energy) has pushed states to identify water bodies for floating solar deployment; a draft national floating solar policy was under review in February 2026.
- Advantages of floating solar: Reduces water evaporation (15–35% reduction), avoids land acquisition costs and conflict, takes advantage of cooling effect of water to improve panel efficiency, and can be co-located with hydropower reservoirs (hybrid generation).
- NHPC (National Hydroelectric Power Corporation) has announced plans for 2+ GW of additional floating solar at reservoirs in Andhra Pradesh, Bihar, and Odisha by 2027.
- Key risk: Structural durability in monsoon conditions, biofouling, and water quality impacts require robust engineering standards — NISE and IIT Roorkee are developing national standards.
SECL's mine water bodies in Chhattisgarh — particularly in the Korba and Surguja coal fields — are well-suited for floating solar deployment. The JV model with the state government enables land-use clearance, power purchase agreements, and shared infrastructure cost, making it more bankable than a standalone SECL project.
Coal India and Its Subsidiaries: Energy Transition Context
Coal India Limited (CIL) is a Maharatna CPSE and the world's largest coal-mining company by output, accounting for approximately 80% of India's domestic coal production. SECL is one of CIL's seven operating subsidiaries (along with NCL, SECL, MCL, WCL, BCCL, CCL, ECL, and NEC). As India pursues its 500 GW renewable energy target, CIL and its subsidiaries face a dual mandate: continue producing coal to meet near-term energy security needs while transitioning their business model toward net zero.
Key Details
- CIL's coal production: Target of 1 billion tonnes per annum by FY 2026-27 (domestic energy security mandate).
- SECL's Gevra Mine (Korba, Chhattisgarh): Will become the world's largest coal mine by output (~100 MT/year) by 2027.
- CIL's renewable energy target: 3,000 MW of renewable capacity across its subsidiaries.
- Just Transition challenge: Chhattisgarh, Jharkhand, and Odisha are coal-bearing states where mine closure and energy transition have major implications for employment (CIL employs approximately 2.5 lakh workers) and state revenue.
- CIL subsidiaries are exploring diversification into solar power, critical minerals, coalbed methane (CBM), and coal-to-chemicals — SECL's JV proposals reflect this broader strategic diversification.
- Critical minerals connection: Chhattisgarh's geological profile also contains deposits of minerals like tin, bauxite, and rare earth elements — SECL and Chhattisgarh exploring critical minerals JVs aligns with India's Critical Minerals Mission.
The SECL-Chhattisgarh JV model — combining a state government's land/regulatory access with a CPSE's capital and technical capacity — is emerging as a replicable template for coal companies to fund their clean energy transition while maintaining operational viability during the energy transition period.
- SECL's solar target: 700 MW of solar capacity including floating solar.
- SECL's net-zero goal: 2030.
- Gevra Mine (Chhattisgarh): On track to become world's largest coal mine by 2027.
- National Coal Gasification Mission: 100 MT gasification by 2030; investment of ₹85,000+ crore.
- VGF for gasification: ₹8,500 crore (Cabinet approved, January 2024).
- India floating solar installed capacity: approximately 700 MW (late 2025); technical potential ~100 GW.
- India floating solar 2030 target: 10 GW.
- India's methanol import dependence: approximately 90%; ammonia: 13–15% — gasification can address both.
- CIL's coal production target: 1 billion tonnes/year by FY 2026-27.
- CIL renewables target across subsidiaries: 3,000 MW.
