Bihar has successfully commissioned the first phase of a large solar-plus-battery storage project in Kajra, Lakhisarai district.
Key Points
- Implementing Agency: The project is being executed by Bihar State Power Generation Company Limited (BSPGCL), the state-owned power utility.
- Project Capacity: The total project capacity is 301 MW solar power combined with 495 MWh battery storage.
- This makes it one of the largest solar-plus-storage projects in eastern India.
- Phase-I: The first phase consists of 185 MW solar capacity with 254 MWh Battery Energy Storage System (BESS).
- Technology Used: The battery storage system uses Lithium Iron Phosphate (LiFePO₄) technology, known for higher thermal stability and safety.
- BESS Function: The BESS enables storage of excess daytime solar power and supplies electricity during peak evening demand hours.
- Grid Integration: Power from the project is evacuated through a 132 kV transmission system, ensuring seamless integration with the state power grid.
- Second Phase: The remaining 116 MW solar and 241 MWh BESS will be commissioned in the next phase, expected by January 2027.
- Strategic Importance: The project supports Bihar’s long-term goal of increasing the share of renewable energy and reducing dependence on conventional fossil-fuel-based power.
- Environmental Significance: Solar-plus-storage projects help reduce carbon emissions, improve energy security, and promote sustainable power generation.
