In hydro electric projects, grouting plays an important role in controlling the seepage and improvement in rock strength for the construction of underground as well as surface structures. The Nathpa Jhakri Hydroelectric Power Station (NJHPS) 1500 MW, the largest hydropower station in India under operation, and downstream Rampur Hydro Electric Project (RHEP) 412 MW, presently under advanced stage of construction, and planned to run in tandem are both located on river Satluj in the Himalayan region.
The Satluj Jal Vitaran Nigam (SJVN) Limited is set to generate 6,900 million units of power during the financial year 2011-12, which is beyond all the targets set and achieved in the past.
The SJVNL has signed an MoU with the Government of India for generation of 6,900 MU power with an expected revenue realisation of Rs 1,718 crore during the next financial year from its 1,500 mega watt Nathpa
New Delhi: In an indictment of ham-handed approach towards infrastructure projects, the World Bank is downgrading the 412mw Rampur hydel plant being constructed in Himachal Pradesh by Satluj Jal Vidyut Nigam Ltd, which recently concluded its IPO, on ground of tardy progress and management slack arising from long-pending vacancies on the board.
The Rampur hydroelectric project, downstream of Nathpa Jhakri hydro electric project (NJHEP) in Himachal Pradesh, is the second unit in the country that will use the water discharge of an upstream power station.
Facing huge financial losses on account of disruption in generation due to excessive silt and ensuring the mandatory 15 per cent water discharge, the Satluj Basin, Forum of Hydro Power Producers have sought the holding of a cumulative impact study to assess the problem.
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.
Power generation resumed after eight days at the 1,500-MW Nathpa-Jhakri project this afternoon. Engineers of the Sutlej Jal Vidyut Nigam (SJVN) decided to start the project after the discharge in the Sutlej started declining after attaining the peak of 1,550 cumecs last evening. The first unit of 250 MW started functioning at noon and four units out of total six had been made operational by the evening.
