Summary

The construction of Telli Hydropower Project is in operation since 2012. Project makes use of the head between 665 m and 455 m of Akdere Creek.

Penstock, one of the most important components of the project, is made of steel pipe with a length of 3.037 m and diameter of 1.70 m. The penstock was placed such that the first 2 312 m of it will be laid under the nearby village road and the reaming 725 m part will be placed in a tunnel coated by concrete. The penstock is connected to the power plant via the bifurcation at the tunnel exit, thereby eliminating the need for forebay which in turn reduces the negative social and environmental effects as well as the total cost. An economical design of penstock was achieved by taking the advantage of the use of Pelton type turbines which are able to keep pressure rise at a reasonable level.
