Kajra Solar Power Plant: India’s Largest Battery Storage System Lighting Up Bihar’s Green Future Published By Anupam Nath India is entering a new era of renewable energy, and the state of Bihar is now set to take a giant leap forward with the Kajra Solar Power Plant, officially recognized as the country’s largest battery storage system. Located in the Lakhisarai district, this cutting-edge green energy project represents a tremendous stride toward sustainability, reliability, and affordability in India’s power sector.The Kajra Solar Power Plant, developed under the guidance of the Bihar State Power Generation Company (BSPGCL), is designed to supply 185 megawatts (MW) of clean solar power integrated with advanced battery storage. This innovative combination ensures uninterrupted electricity even during non-sunny hours and helps balance the grid during peak demand periods — a crucial breakthrough for Bihar’s power infrastructure.According to energy officials, the commercial supply of electricity will begin in February 2026, following successful trial runs. The energy generated here will be sold to South and North Bihar Power Distribution Companies at an initial rate of ₹4.60 per unit, decreasing gradually over time. This long-term rate reduction plan, spread across 25 years, reflects Bihar’s commitment to making green power not only sustainable but also economically viable.The impact of this project will be felt across the state. Over 20 million consumers are expected to benefit from affordable and reliable electricity, reducing dependency on fossil fuels and cutting CO₂ emissions considerably. The battery storage technology will stabilize Bihar’s power grid during high-demand periods, ensuring smoother distribution and preventing power outages, especially during extreme weather or summer peaks.Energy Secretary Manoj Kumar Singh hailed this development as a “major milestone in Bihar’s renewable energy journey,” emphasizing how the integration of solar power with battery storage will redefine the state’s energy reliability. This step aligns with India’s national goal of achieving 500 GW of renewable energy capacity by 2030, as envisioned under the clean energy transition roadmap.Beyond producing electricity, the Kajra project also serves as an inspirational model for other Indian states. It demonstrates how a well-planned blend of solar energy and storage technology can enable large-scale energy security and self-reliance. By leveraging natural resources and technological innovation, Bihar is not only powering its cities and villages but also positioning itself as a leader in India’s green revolution.As the sun shines over Kajra’s expansive solar panels, it reflects more than clean energy — it highlights hope, progress, and a sustainable future for millions of families across Bihar.
