Significance of the milestone
The successful completion of the 72-hour trial run represents a critical step in the commissioning process for STPL. A 72-hour continuous trial run is a standard requirement in the power sector before a generating unit is declared commercially operational, demonstrating the unit's ability to sustain stable generation over an extended period.
SJVN Chairman and Managing Director Bhupender Gupta stated that with the successful completion of the trial run, the company is now set for the commercial operation of Unit-2. Director (Finance) Parthajit De highlighted that this achievement strengthens SJVN's generation portfolio and reinforces its position as a multidimensional energy company.
The 1,320 MW Buxar Thermal Power Project, implemented by wholly owned subsidiary STPL, uses state-of-the-art supercritical technology. The project comprises two units of 660 MW each and is equipped with advanced emission control technology. Once fully commissioned, the project will generate approximately 9,828.72 million units of electricity annually.
Director (Projects) Rajesh Kumar Chandel described the completion as a significant achievement in SJVN's thermal power journey, while Director (Personnel) Ajay Kumar Sharma commended the team's professionalism and commitment despite various challenges.
