Media reported that about 30 engineers and employees working at operationalizing a new turbine at the Uhal Stage III hydropower project in Mandi district of Himachal Pradesh had a miraculous escape when the feeder penstock pipeline burst and flooded the hydropower station. On Saturday night when the engineers were working on the heavy machinery, there was a sudden blast in the penstock pipeline and it burst. It took a 6 hour rescue operation to rescue the 20 engineers and employees who were working at the station when the accident occurred. The accident occurred when the engineers were testing the installation of a 33.3 MW new turbine at the plant when the generation was increased to 16 MW. The load of machinery was to be increased up to 32 MW but the penstock could not sustain the water pressure. The powerhouse now contains debris that must be cleared out, and commissioning will be delayed

The Uhl hydropower project is owned and operated by the HP State Electricity Board
