Gunib hydroelectric power station. Worker inspecting machinery in the turbine hall of the Gunib hydroelectric power station in Dagestan, Russia. The majority of the large cylindrical rotating structure is out of view below the floor. This power plant's other two turbine heads are seen in the background, with control panels for the machinery. Water runs through the turbines from the reservoir behind the hydroelectric dam, to the river below, generating electricity in the process. These are vertical Francis turbines, driving generators of 5 MW (megawatt) capacity. Construction of this dam, on the Kara-Koisu River, began in 1995. The power plant began operating in 2005. Photographed on 5 May 2005.
