Tamil Nadu is launching its first solar-plus-battery energy storage projects, marking a pivotal shift toward round-the-clock (RTC) green power. Discover how a 30 MW/90 MWh Solar+BESS hybrid plant and a 500 MW/1,000 MWh standalone storage system, set for operation by December 2026, will store excess solar energy for use during non-solar hours . Learn how M/s eclouds Energy LLP is enabling smarter, cost-efficient, and sustainable energy solutions for a greener future.

Industry Review: Tamil Nadu Accelerates Storage Deployment to Deliver Reliable Renewable Power

Clear Transition Toward Round-the-Clock Renewable Energy

TNGECL's finalisation of multiple battery storage tenders signals a decisive move by the state to overcome solar power's intermittency. By storing surplus energy generated during daylight hours and discharging it during evening peak periods, these systems ensure grid stability, reduce power purchase costs, and make renewable energy dependable—24 hours a day .

Battery Storage Becomes the Preferred Enabler for Renewable Integration

The exponential growth in solar and wind installations across the state has created an urgent need for storage solutions. Tamil Nadu has now finalised tenders for 1,000 MWh of battery energy storage systems (BESS) to provide assured round-the-clock green power, with a landmark 375 MW/1,500 MWh project already awarded in January 2026 at a discovered tariff of ₹3.15 lakh per MW per month . These systems provide long-term tariff stability, better financial planning, and compliance with sustainability norms—making storage the most preferred model for ensuring reliable renewable supply.

Role of Hybrid Projects in Driving Market Innovation

A 30 MW/90 MWh Solar+BESS hybrid plant is also in the pipeline, representing the state's first integrated solar-plus-storage project . Combined with multiple policy initiatives including the Pumped Storage Policy 2024, these projects have become a strategic tool for Tamil Nadu to firm up renewable power while diversifying its energy mix.

Implications for the Future Energy Market

TNGECL expects commercial operation of the 500 MW/1,000 MWh BESS project by December 2026, with additional storage capacity in development . The future will see stronger adoption of integrated renewable projects with storage, hybrid models combining solar, wind, and batteries, and energy storage solutions as the state optimises cost structures and enhances operational resilience. A new Integrated Renewable Energy Policy is set to be released soon to accelerate this transition .

Conclusion

The market shows that battery storage and solar-plus-hybrid projects are no longer optional—they are now the main way Tamil Nadu plans to deliver round-the-clock green power.
