What Happened
- Coal India Limited (CIL) spent ₹961 crore on solar energy capital expenditure (capex) in the period April–January FY2025-26, a 2.33-fold jump from ₹412 crore in the comparable period the previous year.
- This spending has not only outpaced the year-on-year comparable period but also surpassed CIL's full-year FY26 solar capex target of ₹957 crore, reaching 132% of the progressive target of ₹729 crore set for April–January.
- CIL's long-term renewable energy goal is to install 3,000 MW (3 GW) of solar capacity by FY2027-28, contributing to its plan to become a net-zero entity.
- As of December 2025, CIL and its subsidiaries had installed 247 MW of renewable energy capacity; this is expected to rise to 675 MW by end of the current fiscal year.
- Upcoming major projects include a 100 MW plant in Patan, Gujarat, and a 300 MW project in Khavda, Gujarat.
- The cost of setting up 1 MW of solar capacity has fallen to ₹4–4.5 crore, down from ₹5.5–6 crore, reflecting technology cost deflation.

Coal India Limited (CIL): Corporate Structure and National Significance
Coal India Limited is a Maharatna Central Public Sector Enterprise (CPSE) under the Ministry of Coal. Incorporated in November 1975 as a government holding company, CIL is the world's largest coal-producing company. It accounts for approximately 80% of India's domestic coal production. CIL is listed on both the BSE and NSE and the Government of India holds over 63% equity stake. Coal supplies approximately 55% of India's primary energy and remains the backbone of thermal power generation (which accounts for ~75% of India's electricity).
- Incorporated: November 1975; Headquarters: Kolkata
- Classification: Maharatna CPSE (Ministry of Coal)
- Market share: ~80% of India's total coal production
- Government equity: ~63% (as of 2025)
- Annual coal production: ~773 million tonnes (FY25)
- Subsidiaries: 7 coal-producing companies + 1 mine planning company (e.g., SECL, BCCL, ECL, MCL)
Connection to this news: CIL's solar capex surge represents a strategic pivot by the world's largest coal producer toward renewables — significant both for India's energy transition and for understanding the role of legacy fossil fuel PSUs in the green economy.
Energy Transition and PSU Diversification Strategy
India's energy transition refers to the shift from fossil fuel-dominated to renewable energy-dominated electricity generation. Under the National Action Plan on Climate Change (NAPCC), the National Solar Mission (now PM-KUSUM and PM Surya Ghar Muft Bijli Yojana) and India's Nationally Determined Contribution (NDC) to the UNFCCC, India has committed to 500 GW of non-fossil electricity capacity by 2030 and net-zero emissions by 2070. CPSEs like CIL are being nudged to diversify into renewables through capex mandates, recognising that their mining land, financial resources, and infrastructure can be repurposed for solar parks.
- India's 500 GW renewable energy target by 2030 (per updated NDC submitted to UNFCCC)
- India's net-zero target: 2070 (announced at COP26, Glasgow)
- CIL's renewable target: 3,000 MW solar by FY28; broader coal sector target: 9 GW renewables by 2030
- Solar cost trajectory: ₹5.5–6 crore/MW (few years ago) → ₹4–4.5 crore/MW (now), reflecting ~25–30% cost reduction
- CIL's current installed RE capacity: 247 MW (Dec 2025); FY26 target: 675 MW
- CIL's diversification: Solar, wind, coal-to-chemical, underground coal gasification, critical minerals
Connection to this news: CIL's 2.33x capex jump in solar demonstrates that even the most carbon-intensive PSU can accelerate green investment when incentivised and mandated — a test case for India's just energy transition strategy.
Just Transition and the Coal Economy
"Just transition" refers to a policy framework that ensures workers and communities dependent on fossil fuel industries are not left behind as economies shift to clean energy. India's coal sector employs approximately 4 lakh workers directly (CIL alone) and supports millions of livelihoods indirectly in regions like Jharkhand, Chhattisgarh, Odisha, and West Bengal. CIL's solar diversification is one mechanism through which just transition is being operationalised — retaining the company and its workforce while shifting its revenue streams.
- CIL direct employees: ~2.5–3 lakh (as of recent data)
- Coal-dependent districts in India: 40+ districts classified as high coal-dependency (coal belt states)
- International Just Transition frameworks: ILO Guidelines on Just Transition; COP28 UAE Consensus on fossil fuel phase-down
- India's position: Supports "phasing down" (not "phasing out") coal, especially given energy access needs
- CIL's net-zero plan does not include shutting mines — it involves adding renewable capacity alongside coal operations
- Economic rationale: Solar parks on mine land leverage existing land-bank, reduce transmission costs
Connection to this news: CIL's ₹961 crore solar capex is not just a financial story — it illustrates how India's just transition approach allows the coal sector to co-exist with renewables rather than be displaced abruptly.
