The Expert Appraisal Committee for River Valley and Hydroelectric Projects has recommended environmental clearance for SJVN Limited's 680 MW Attunli Hydroelectric Project in the Dibang Valley district of Arunachal Pradesh.
Attunli is a run-of-river project built around an 85-metre concrete gravity dam on the Tangon, also called the Talo, river.
Its underground powerhouse will hold four Francis turbines of 170 MW each and the project is expected to generate about 2,728 million units a year.
The project needs the diversion of 261.53 hectares of forest land, for which Stage-I forest clearance was granted in June 2026.
Originally conceived by a joint venture of Jindal Power and the Hydro Power Development Corporation of Arunachal Pradesh, the project was later allotted to SJVN.
Under the Environment Impact Assessment Notification of 2006, a project of this category is appraised by an Expert Appraisal Committee constituted by the Ministry of Environment, Forest and Climate Change. The committee examines the environmental impact assessment and management plan and then recommends grant or refusal; the actual environmental clearance is issued by the regulatory authority, not by the committee itself. Running in parallel and quite separately, any diversion of forest land requires approval under the forest conservation law, which comes in two stages: Stage-I, an in-principle approval carrying conditions, and Stage-II, the final approval once those conditions are met. A project can hold Stage-I forest clearance and a favourable environmental appraisal and still not be free to start work.
Simple Analogy: The appraisal committee is the examiner who recommends a pass; the certificate is issued by someone else, and the forest department runs a completely separate examination.
