Adani Group plans Rs 27,000 crore thermal power investment in Bihar
Adani Group has announced plans to expand its investments in Bihar’s power sector, including a 2,400 MW ultra-supercritical thermal power project at Pirpainti in Bhagalpur district and large-scale smart meter deployment across north Bihar.
According to statements made by Gautam Adani during a visit to Bihar, the group is investing around Rs 27,000 crore in the 2,400 MW thermal power project, which is being positioned among the largest private sector investments in Bihar’s power sector. The project is expected to support the state’s energy self-reliance goals.
The project is being developed by Adani Power Limited at Pirpainti block across seven villages, Simatpur, Mariakol, Mundwa urf Tundwa, Sundarpur, Mayanagar, Pirpainti and Raipur, over 479 hectares allotted by Bihar State Power Generation Company Limited. It will comprise three units of 800 MW each using ultra-supercritical technology. In March 2026, the Expert Appraisal Committee (EAC) for Thermal Projects recommended environmental clearance for the project.
In the power distribution segment, Adani Energy Solutions Limited is installing nearly 3 million smart meters across north Bihar to modernise the electricity distribution system. As of March 2025, Bihar was among only five states with active prepaid meters and had achieved a 78% communication rate on installed meters, significantly above the national average for major states of 5.7%.
The state has also awarded all sanctioned meters and ensured that 100% of installed meters operate in prepaid mode. In comparison, implementation has not started in Tamil Nadu, while no data has been reported for Telangana. Bihar is also the only state with regulatory provisions specifying timelines for meter testing and recalibration, creating a stable policy framework for the deployment of the 3 million smart meters.
Overall, the Adani Group indicated plans to invest between Rs 50,000 crore and Rs 60,000 crore in Bihar over the next three to four years across multiple infrastructure sectors, including power and energy.
