The Jurala hydro electric power house located in Atmakur of Mahbubnagar district of Telangana has been inundated due to dam flood water entering the power installations.

The Chairman and Managing Director of TS Genco, D. Prabbhakar Rao, along with chief engineers reached the Jurala project site today morning to speed up the restoration works.

Efforts are on to restore two units of 40 MW each which have been inundated.

The incident occurred late last night when the water released from Jurala flooded the power units.

Construction work

According to a statement from TS Genco, the construction works of Lower Jurala Hydro Electric Power House (6x40 MW) were in progress. All the works in respect of units 1 & 2 were completed during the last monsoon season and they were planned to be synchronised in August 2014.

In this process, all the necessary measures were taken to facilitate water filling of upstream intake and downstream and the flood water from dam was let out on July 30 at about 6 p.m.

Inspection of power house

After attaining an elevation of 297 m on upstream side at about 9 p.m. all the engineers concerned from TS Genco and the contractors were inspecting from inside of the power house to find any leakages and to take immediate measures.

The leakages during inspection were found to be very negligible up to 10.05 p.m.. Just about that time, a sudden gush of water was observed through the upstream gates of Unit No.4.

Inundation of power house

Immediately after forecasting the danger of inundation of power house, all necessary evacuation measures were taken up on a war footing and human loss was avoided. The downstream gate of Unit No.4 was opened to avoid complete inundation of power house. Further, the electrical control panels in the power house were also kept safe from inundation.

The extent of damage occurred to the power house would be known after carrying out dewatering of intake and power house areas. The formation of earthen bund on upstream side has been taken up along with dewatering after completing the bund. The earthen bund and dewatering are expected to be completed in about 5 to 6 days.

Meanwhile, water inflow into the Jurala project is in excess of one lakh cusecs and is being let out downstream. The water thus let out is reaching Srisailam dam.
