Hydro power plants located on the Himalayan rivers, typically, have had to endure high silt content in the water passing through the turbines causing enormous damages to the under-water parts of the turbine. The hydro power generating companies are engaged in mitigating this menance and optimizing generation and profits. The Nathpa Jhakri Hydro Power Station (NJHPS) - the flagship power station of the Satluj Jal Vidyut Nigam (SJVN)- bore the brunt of heavily silt laden water consisting of highly erosive Quartz particles, in the first few years of operation after commissioning in 2003-04. Through a series of silt control measures, based on expert advice and experience gained by SJVN over the years, SJVN is close to finding a lasting solution to the problem towards achieving an optimum interval between successive repairs.
