The Rudbar-e-Lorestan dam and hydropower project will consist of a 180 m high roller compacted concrete dam to create a reservoir with an estimated gross capacity of 228 million m3. Water from the reservoir will be diverted through a 3 km long headrace tunnel into the adjacent valley and hence in twin surface steel penstocks down to the power house on the bank of the Alkan river, developing a design gross head of 442 m and 450 MW total installed capacity.

Pöyry’s will provide the construction design and support during construction for the dam and headrace tunnel. The value of the assignment amounts to about €7 million.
