Four new units for a hydropower plant in Turkey
In May 2012, Özdogan Enerji A.S. signed a contract with ANDRITZ HYDRO for the supply of an electromechanical Water-to-wire solution for the new Ayvali hydropower plant in Turkey. In August 2013, this contract was extended to include two COMPACT units using the obligatory residual water flow.
HPP Ayvali is located on the Oltu branch of the Çoruh River, in the province of Erzurum in northeastern Turkey, close to the border with Georgia. It features a roller compacted concrete (RCC) dam with a height of 177 m, a maximum dam reservoir of 308 million m³ and an installed capacity of 130 MW.
