Hydro power stations at Borcka and Murati in Turkey will be supplied under turnkey contracts by a consortium led by va-tech Elin, it was announced in March. The order was placed by Turkey’s General Directorate of State Hydraulic Works and it is worth some ASh2.3B (US$184M) to VA Tech Elin. The total investment for the two projects is ASh7.5B (US$600M).
The Borcka plant takes advantage of an 86m high dam at the intersection of the Coruh and Murgul waterways, and it will house two power units each rated at 150MW. The reservoir at the site has a storage capacity of 420M m3. The Murati plant is the last stage of the 11 hydro power plants along the Coruh river. The 44m high dam, impounding 75M m3, will be equipped with two 57.5MW generators.
The consortia will also include VA Tech Voest, Verbundplan, strabag and Voith Hydro, as well as Turkish companies Temelsu and Yüksel. Among the scope of work, VA Tech Elin will supply, deliver and install two generators for each plant, along with high and low voltage plants, control systems, protection and excitation equipment. VA Tech Voest will engineer, deliver and install hydraulic steel construction equipment, penstocks and cranes, and will deliver two vertical Francis turbines for Murati. Voith Hydro will deliver two vertical Francis turbines for Borcka. Verbund- plan is responsible for basic construction engineering and co-ordination, while Strabag will execute some civil works.
Both the Borcka and Murati plants have been entirely financed from outside Turkey. The total US$600M financing includes two export credits and seven commercial loans, and the lenders are: Societe General; Nissho Iwai; ABN Amro; KFW; and Erste Bank and RZB.
