The Bihar government has commissioned the first phase of the Kajra Solar Power Plant, a large-scale renewable energy project in the Lakhisarai district designed to boost the state’s clean power mix. Developed under the Bihar State Power Holding Company Ltd, the project stands out for pairing utility-scale solar generation with grid-connected battery storage. This combination is intended to stabilize power supply and support rising electricity demand with lower emissions.
In its initial phase, Kajra features a 185-megawatt solar facility integrated with a 254-megawatt-hour battery energy storage system, backed by a new transmission line and transformer infrastructure for power evacuation. According to Bihar’s energy department, the battery system enables four to five hours of continuous supply during peak demand windows. A second phase is underway that will add another 116 megawatts of solar capacity and 241 megawatt-hours of storage, with full project completion targeted by January 2027.
For consumers, the Kajra project signals a shift toward more reliable, cleaner electricity in a region historically challenged by grid constraints. The solar-plus-storage model helps smooth intermittency, supporting steadier voltage and reducing outages during high-use periods. On a broader level, it illustrates how emerging markets are adopting hybrid renewable infrastructure to meet climate goals while enhancing everyday energy access, positioning battery-backed solar as a scalable template for future grid upgrades.
