Shimla, Aug 8: Hydropower plant in Himachal Pradesh remained shut for the fourth day on Sunday, Aug 8, disrupting power supply to northern states, including Delhi.
The 1,500 MW Nathpa Jhakri hydropower project in Kinnaur district was closed on Thursday, Aug 5, as the silt level suddenly rose more than the permissible limit of 4,000 ppm (parts per million) due to heavy rains.
This affected supply to states like Punjab, Haryana and Delhi, among others.
Vijay Verma, deputy general manager of the Sutlej Jal Vidyut Nigam Ltd (SJVNL) said, "the power generation was stopped as silt content in the Sutlej river crossed 36,000 ppm."
This is the fourth closure of the plant in this fiscal. Earlier, the plant was closed for five days from Jul 26 due to rise in silt level.
The closure of power generation has caused a daily loss of Rs 9 crore.
