Buxar Thermal Power Project Uses Supercritical Technology
The Buxar Thermal Power Project is being developed at Chausa in Buxar district, Bihar, using advanced supercritical technology.
The technology is designed to provide higher operational efficiency compared with conventional subcritical thermal power generation while helping reduce the environmental footprint of the project.
Key Project Details
- Project: Buxar Thermal Power Project
- Location: Chausa, Buxar district, Bihar
- Total capacity: 1,320 MW
- Configuration: 2 × 660 MW
- Unit-II capacity: 660 MW
- Technology: Supercritical
- Developer: SJVN Limited through SJVN Thermal Private Limited
- Scheduled commercial operation of Unit-II: September 12, 2026
- Expected annual generation: 9,828.72 Million Units
Project to Generate 9,828.72 Million Units Annually
Once fully operational, the 1,320 MW Buxar Thermal Power Project is projected to generate around 9,828.72 Million Units of electricity annually.
The project is expected to play an important role in meeting growing electricity demand and strengthening the reliability of power supply in Bihar and the Eastern Region.
The use of supercritical technology is also aimed at improving the overall efficiency of the power generation facility.
85% Power Allocated to Bihar
A significant portion of the electricity generated by the Buxar project has been allocated to Bihar.
Under a long-term Power Purchase Agreement (PPA), 85% of the project’s power has been allocated to Bihar.
The allocation is expected to:
- Improve power availability across Bihar.
- Support the state’s growing electricity demand.
- Help reduce peak-hour power shortages.
- Strengthen energy security in Bihar.
- Contribute to improved power availability in the Eastern Region.
The project is therefore expected to have a significant role in supporting the state’s power requirements once both units are fully operational.
Buxar Project Strengthens SJVN’s Power Generation Portfolio
The commercial operation of Unit-II represents another major step in SJVN’s expansion of its power generation capacity.
The company is developing the project through its wholly owned subsidiary, SJVN Thermal Private Limited. With its strategic location and large generation capacity, the Buxar project is expected to contribute significantly to India’s power infrastructure.
The commissioning also strengthens SJVN’s presence in thermal power generation alongside its established portfolio in hydropower and other renewable energy projects.
