Blast at 1000 MW Anpara D Power Plant

A tragic incident took place at the Anpara D power plant in Sonbhadra district of Uttar Pradesh, where a 500 MW turbine had a sudden blast starting a huge fire. Four engineers were injured in the incident.


The turbine was part of 2×500 MW unit number 9 of Anpara D. It was a BHEL supplied turbine currently under operation by Uttar Pradesh Rajya Vidyut Utpadan Nigam Ltd. (UPRVUNL). The fire started after the blast took a huge form, taking in vicinity the instruments on the turbine floor and spreading to the cable gallery. Intensity of the blast was so high that the whole generator was thrown apart with pieces flying into the control room through glass doors. Fire tenders from the nearby Anpara A, B and C units rushed in on the site and took fire under control after hours of effort. The production of 1000 MW has been stopped from the plant creating a crisis of power supply in the eastern districts of Uttar Pradesh.
