Coal India Funds 875 MW Solar Plant with ₹3160 Cr Subsidiary Guarantee

On March 23, 2026, Coal India Limited (CIL), the country's largest coal producer, announced its Board has approved a ₹3160 crore corporate guarantee. This financial backing is for CIL Rajasthan Akshay Urja Limited (CRAUL), CIL's 74% owned subsidiary. The guarantee will fund the capital expenditure for CRAUL's planned 875 MW Solar PV Plant. CRAUL is a joint venture; CIL holds the majority 74% stake, with Rajasthan Rajya Vidyut Utpadan Nigam Limited (RRVUNL) holding the remaining 26%.

Strategic Importance and Risk

This guarantee highlights Coal India's strategic push into renewable energy, supporting the development of a significant solar project that contributes to India's clean energy goals. However, it also means CIL faces a contingent liability. The parent company could be responsible for CRAUL's debt obligations up to the ₹3160 crore amount if the subsidiary defaults.

CIL's Renewable Energy Strategy

Coal India is steadily expanding its renewable energy operations as part of a wider strategy to lessen its reliance on coal and meet net-zero emissions targets. The company aims to have 3 GW of renewable capacity by 2027-28 and 9.5 GW by 2029-30. CIL Rajasthan Akshay Urja Limited (CRAUL) was established on June 12, 2025, to focus on renewable energy projects in Rajasthan. This 875 MW solar project is a key part of CIL's plan to develop large-scale capacity via its subsidiaries and joint ventures.

Key Implications

The guarantee increases Coal India's potential financial exposure by up to ₹3160 crore, tied to CRAUL's project financing. It directly enables crucial capital for adding significant solar capacity, supporting CIL's diversification. If successful, the solar plant could generate future revenue streams for CIL through its subsidiary. The guarantee will appear as a contingent liability on CIL's balance sheet, potentially affecting its overall risk profile and borrowing capacity for other initiatives.

Potential Risks

The primary risk is CRAUL defaulting on its debt obligations, which would require Coal India to pay up to ₹3160 crore under the guarantee. Delays or cost overruns during the construction and commissioning of the 875 MW Solar PV Plant could jeopardize CRAUL's financial health. Additionally, changes in renewable energy policies or regulations in Rajasthan could impact the project's economics. A past report from the Comptroller and Auditor General (CAG) also highlighted concerns about CIL's slow implementation of solar projects.

Industry Context

Coal India is not alone in its renewable energy push. Competitors like NLC India Limited and Singareni Collieries Company Ltd are also investing heavily in renewables as part of their diversification. NLC India aims for over 6 GW of renewable capacity by 2030, and Singareni has also made considerable investments in solar power.

Key Figures

• Corporate Guarantee Amount: ₹3160 crore
• Project Capacity: 875 MW Solar PV Plant
• CIL's Stake in CRAUL: 74%

Investor Watchlist

Investors will be watching the progress and timeline for the 875 MW Solar PV Plant's operational launch. CRAUL's ability to service its debt and its overall financial performance will be key indicators. CIL's broader advancement against its renewable energy installation targets also remains important. Future financial results from CRAUL will help assess the effective deployment of the guaranteed funds.
