Lower Kalekoey, Turkey

Successful synchronization of unit #1

In May 2020, the first unit of Lower Kalekoey, Turkey, was successfully synchronized.


The unit is in operation and the reliability run was successfully stopped on 25.06.2020. Erection of unit #2 and #3 is ongoing. The project should be finished by end of November 2020.

As a member of an international consortium, ANDRITZ has received a contract from the privately owned company Kalehan Genç Enerji Üretim A.S., part of the Kalehan Energy Group for the electro-mechanical equipment for the Lower Kalekoey hydropower plant on the Murat River. The scope of supply includes design, manufacturing, installation and commissioning of three 186 MVA generators and all associated equipment. Each of the three main generators for the plant weighs more than 700 t. Moreover, the contractual scope of work covers excitation and monitoring systems for the three main units, as well as for an environmental unit which will generate power from ecological water flows.


The overall output of HPP Lower Kalekoey amounts to 500 MW and the hydropower plant will produce about 1,200 GWh of electrical energy per year, thus providing important support to the Turkish grid. Commissioning of the plant is scheduled in 2020.
