India’s largest hydroelectric plant at Nathpa Jhakri in Himachal Pradesh has been shut for close to 18 days due to the heavy silt the river on account.
The permissible silt limits are are 4000 ppm (particles per million), the river has silt levels of around 10000 ppm.While they have done some special coating of the turbines, there is some quartzite element in the silt that corrodes the blades.
The cloudburst over Leh in Ladakh, floods in Pakistan and China, and a crippling drought over Russia have left meteorologists poring over weather models and historical data to make sense of why conventional monsoon patterns aren’t playing out over India and its neighbors.
SJVNL, the owner of Nathpa Jhakri has seven HEPs with a combined capacity of 4074.5MW.
