The Cabinet Committee on Economic Affairs (CCEA) on Wednesday approved the expenditure on pre-investment activities and various clearances for Dibang Multipurpose Project (MPP) in Arunachal Pradesh for an amount of Rs 1600 crore.
The estimated completion period for the project shall be nine years from receipt of Government sanction.
The project will generate 2880 MW (12x240 MW) power to produce 11223 MU of energy in a 90% dependable year. This is the largest ever hydroelectric [roject to be constructed in India. The dam is 278 metres high and 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 m high concrete gravity dam (above deepest foundation level), six horseshoe-shaped headrace tunnels of length varying from 300 m to 600 m with 9 m dia., an underground powerhouse and six horseshoe-shaped tailrace tunnels of length varying from 320 m to 470 m with 9m dia.
On completion, Arunachal Pradesh government will get 12% free power from the project i.e. 1346.76 MU.
One percent free power (i.e. 112 MUs) will be given in Local Area Development Fund (LADF). The total value of the benefit to Arunachal Pradesh from free power and contribution to LADF will be Rs 26,785 crore over the project life of 40 years.
Dibang Multipurpose Project is envisaged as a 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 the master plan of Brahmaputra Board for flood moderation of all rivers contributing to river Brahmaputra, of which Dibang MPP is one of the components, a sizable area will be protected from flooding and help in mitigating the perennial damage due to floods in Assam.
The project is having all statutory clearances viz. TEC, Environment Clearance, Forest Clearance (Stage-l) and Defence Clearance except for Forest Clearance (Stage-II) for seeking Investment Sanction from Government of India, an official press release said.
The approval of anticipated expenditure on pre-investment activities and various clearances shall enable payment towards compensation for land acquisition and R&R activities (Rs. 500.40 crore) to project affected families and state government, payment of Net Present Value (NPV) of forests, Compensatory Afforestation (CA), Catchment Area Treatment Plan (CAT) to the state government for forest lands, to secure the Forest Clearance (Stage-lI) and construction of roads and bridges for accessing project site.
In addition to the mandated R&R plan, it is also proposed to spend Rs. 241 crore on community and social development plan and certain concerns raised by the local people during the public hearings. It is also proposed to spend an amount of Rs. 327 lakhs on a plan for the protection of culture and identity of local people, the release added.
