NEW DELHI, July 17 - In a bid to deliver a big boost to power generation in North-East, the Cabinet Committee on Economic Affairs (CCEA) has cleared the largest ever Hydro Electric Project to be constructed in India. An expenditure on pre-investment activities and various clearances for Dibang Multipurpose Project (MPP) in Arunachal Pradesh an amount of Rs 1,600 crore has been sanctioned, official sources announced.
The CCEA meeting chaired by Prime Minister Narendra Modi estimated that total cost of Project is Rs. 28,080.35 including IDC and FC of Rs 3,974.95 crore at June 2018 price level. The estimated completion period for the project shall be nine years from receipt of Government sanction.
Official sources said that the project shall generate 2880MW (12x240MW) power to produce 11223MU of energy in a 90 per cent dependable year. The dam will be the highest dam in India once completed.
The project is located on River Dibang, in Lower Dibang Valley District of Arunachal Pradesh. The project envisages construction of a 278 metre high Concrete Gravity Dam (above deepest foundation level), 6 horseshoe-shaped Head Race Tunnels of length varying from 300 metre to 600 metre with 9 metre dia, an underground Power House and 6 horseshoe-shaped Tail Race Tunnels of length varying from 320 metre to 470 metre with 9 metre dia.
On completion, the Government of Arunachal Pradesh will get 12 per cent free power from the project i.e. 1346.76 MU. 1 per cent free power will be given in Local Area Development Fund (LADF). The total value of benefit to Arunachal Pradesh from Free power and contribution to LADF will be Rs 26,785 crore over the project life of forty years.
Dibang Multipurpose Project (Dibang MPP) is envisaged as storage based hydro-electric project with flood moderation as the key objective. The construction of Dibang MPP shall prevent the sizeable downstream area from floods. After implementation of master plan of Brahmaputra Board for flood moderation of all rivers contributing to river Brahmaputra, of which Dibang MPP is one of the components, sizable area will be protected from flooding and help in mitigating the perennial damage due to floods in Assam.
