Kolkata, India — Coal India Limited has secured a major battery energy storage project worth approximately ₹1,057 crore (about $127 million), marking a significant step in its transition toward clean energy infrastructure.
The state-run mining giant announced that it has received a Letter of Award (LOA) from Telangana Power Generation Corporation Limited for the development of a 750 MWh Battery Energy Storage System (BESS) project in Choutuppal, located in the southern Indian state of Telangana.
The company disclosed the development to stock exchanges, including the Bombay Stock Exchange and the National Stock Exchange of India, in compliance with regulatory requirements.
Project Details and Timeline
The project involves setting up a 187.5 MW / 750 MWh battery storage facility, designed to supply stored energy for up to four hours. Key highlights include:
- Project Cost: ₹1,057.09 crore (~$127 million)
- Tariff: ₹3.14 lakh per MW per month
- Execution Timeline: 18 months from the signing of the Battery Energy Storage Purchase Agreement (BESPA)
- Contract Type: Domestic order
- Promoter Interest: No related party transactions involved
Coal India is required to submit necessary documentation within 15 days and provide a Performance Bank Guarantee before finalizing the BESPA.
Strategic Shift Toward Clean Energy
The project represents a crucial milestone in Coal India’s broader strategy to diversify beyond its traditional coal mining operations.
As India accelerates its energy transition, the company has been expanding into renewable energy, solar power, and energy storage solutions. The BESS project aligns with national goals to reduce carbon emissions and improve energy efficiency.
Battery Energy Storage Systems play a vital role in modern power infrastructure by:
- Stabilizing intermittent renewable energy sources such as solar and wind
- Managing peak electricity demand
- Enhancing overall grid reliability
Boost for Telangana’s Power Infrastructure
The project is expected to strengthen Telangana’s electricity grid and facilitate greater integration of renewable energy into the state’s power mix. With increasing renewable capacity, energy storage is becoming essential for ensuring a stable and reliable supply.
Market and Industry Implications
This award signals Coal India’s growing ambition to reposition itself as a diversified energy company rather than solely a coal producer. The move reflects a broader trend in India’s energy sector, where investments in grid-scale battery storage are rapidly gaining momentum.
As demand for clean energy infrastructure rises, Coal India’s entry into large-scale storage projects could enhance its long-term growth prospects and relevance in a decarbonizing economy.
