Consultancy services sought to design Dibang dam in India

Bids are sought from qualified consultants for a feasibility study into the design of the Dibang dam.

India’s state power producer NHPC, formerly the National Hydroelectric Power Corporation, invites bids by 9 January from qualified consultants to carry out a feasibility study to explore the design suitability of constructing the Dibang dam in the northeastern state of Arunachal Pradesh as an RCC structure.

The dam is planned with a height of 278 m, which would make it India’s largest dam and the world’s tallest concrete gravity dam, according to NHPC’s website.

The Dibang multipurpose project, which is to be located on the river Dibang in the Lower Dibang Valley, about 1.5 km upstream of the confluence of the Ashu Pani and Dibang rivers, is still awaiting central government approval. The project is also planned with a 2880 MW hydropower plant, equipped with 12 units of 240 MW, which would have a design annual output of about 11.2 TWh. In addition, the dam is designed to provide flood control during the monsoon period.
