Chhattisgarh Solar Milestone: CERC Approves ₹4.01/kWh for 100 MW Solar-Plus-Storage Project
The Central Electricity Regulatory Commission (CERC) has greenlit a landmark ₹4.01/kWh tariff for Chhattisgarh’s 100 MW solar PV plant integrated with 40 MW battery energy storage (BESS) – a significant boost for Chhattisgarh’s solar energy policy and India’s renewable transition.
Understanding the Solar-Plus-Storage Tariff Structure
While ₹4.01/kWh appears higher than record-low solar tariffs, this hybrid project delivers crucial dispatchable power through battery storage integration, ensuring reliable supply even after sunset.
Project Specifications:
- 100 MW solar capacity (powers ~75,000 homes)
- 40 MW lithium-ion battery storage system
- 25-year power purchase agreement
Strategic Importance for Chhattisgarh
Known for coal reserves, Chhattisgarh is strategically expanding renewables with this project complementing its open access solar policies. The state’s 5.5 kWh/m²/day solar irradiation exceeds European averages.
Industry Implications
This approval establishes a valuable precedent for solar-plus-storage projects, potentially accelerating hybrid developments nationwide. It also validates location-specific tariff models for regions with unique infrastructure challenges.
Financing Considerations
While technically viable, financing remains challenging with Indian banks still cautious about battery storage technology, potentially requiring international financiers for similar projects.
Future Outlook
With battery costs down 80% in a decade, more states may adopt this model, testing discoms’ willingness to pay for reliable renewable power versus conventional alternatives.
