Turbines of hydroelectric projects in HP come to halt

Rains disrupts normal life in HP as well as power production

Shimla/ August 21

The high level of silt has shut down the turbines of many major hydroelectric projects in Himachal. These include country’s largest Nathpa-Jhakri hydropower (1500 MW), Karchham-Wangtoo (1000 MW) and Chamera -I and Chamera-II (231 MW) which were shut down since yesterday due to alarming rise in silt level.

While the other hydroelectric projects Bhawa ( 120 MW), Andhra in Shimla distrci  both owned by Himachal Pradesh State Electricity Board Limited (HPBSEL)  were also shut on early Tuesday morning hours. “Both these projects had stopped generating electricity on 3 A.M this morning due to increased level of silt,”Power Controller, HPSEBL, Joginder Singh said.

Nathpa Jhakri power plant has been closed from 10.30am on Monday after the silt level was found to be very high in Sutlej “In the evening hours silt level was found to be between 26,000 to 27,000ppm, additional general manager (corporate communication) of SJVN, Vijay Kumar Verma said .

“It is not safe to run the plant as high silt level in the water damages the machines. Plant would be started only when silt level would decrease,” he said. In 24 hours, Nathpa Jhakri plant produces 36 million units of power and on Monday the entire generation was lost.

The silt level rose to 57000 ppm (particle per million) at Khab while it was 13000 ppm at Nathpa dam against permissible level of 4000 ppm. The situation was worse in Karchham -Wangtoo  and Baspa projects was no better and all the units of these projects generating about 3400 MW power have been closed to avoid damage to heavy machinery due to high silt level  and in case the power generation was not resumed by tomorrow, the region would face acute power shortage.
The power generated through these three power plants is fed to the northern grid that caters to 28% of the country’s population.

Himachal Pradesh is witnessing heavy rainfall in the higher hills due to which the silt level has increased in the rivers.
