Nuozhaodu Hydropower Project
Norconsult is carrying out the consultancy services for the project. The Nuozhadu Hydropower Project is located in Yunan Province, China, close to the boundaries to Thailand and Myanmar (Burma), in the downstream part of the Lancang (Mekong) River.

The project is under construction utilizing 187m head in 9 units with a total install capacity of 5850 MW. It is planned to be completed in June 2015.

The earth and rockfill dam is 261.5m high. The underground powerhouse complex consists of three major caverns, i.e. the machine hall (418m x 31m x 81.6m; length x width x height), the transformer hall (346m x 19m x 23.6m) and three tailrace tunnel surge chambers (shafts of  33m diameter after concrete lining and height of 92m), with overburden from 184m to 220m.
