Bihar has taken a major step in strengthening its renewable energy infrastructure with the commissioning of the first phase of the Kajra Solar Power Project in Lakhisarai district. Developed at an overall cost of ₹2,800 crore, the project is expected to significantly boost the state’s clean energy capacity and contribute to a sustainable energy transition.
The first phase includes a 185 MW solar power plant supported by a 254 MWh battery energy storage system (BESS), built at an estimated cost of ₹1,810 crore. The Bihar government has also completed the associated transmission infrastructure, including energisation of the transmission line and transformer facility, ensuring smooth evacuation of power from the plant.
Official Statement on Benefits
Bihar Energy Secretary and Chairman-cum-Managing Director of Bihar State Power Holding Company Limited, Manoj Kumar Singh, highlighted the benefits, stating,
“The battery energy storage system will enable the plant to supply uninterrupted electricity for four to five hours during peak demand periods. This is expected to improve grid stability and reduce dependence on conventional power sources.”
The project is being implemented in two phases. The second phase will include a 116 MW solar power plant along with a 241 MWh battery energy storage system, currently under construction at an estimated cost of ₹1,055 crore. This phase will further enhance Bihar’s renewable energy capacity and storage capabilities.
Total Capacity and Timeline
Once fully completed, the Kajra Solar Power Project will have a total installed capacity of 301 MW, supported by 495 MWh of battery storage. The Bihar government aims to commission the entire project by January 2027, marking a key milestone in the state’s renewable energy expansion.
The successful commissioning of the first phase is expected to improve grid reliability, support peak demand management, and reduce the state’s reliance on conventional power sources, reinforcing Bihar’s commitment to clean energy and a sustainable energy future.
