Iron Gate (Serbia-Romania)

Iron Gate is the largest dam on Danube River. Located between Romania and Serbia, this is one of Europe's largest Hydroelectric power plants (two stations). 

Iron Gates is a scenic gorge that forms part of the Serbia-Romania border. The waterway is approx 134 km (83 mi) long. The hydroelectric dams are two, the larger being "Iron Gate I" (1971-opened, reservoir capacity 2,1 km3 / 0,5 mi3, surface area 104,4 km2 / 40,3 mi2) and the smaller one is "Iron Gate II" (1984-opened, reservoir capacity 0,6 km3 / 0,14 mi3, surface area 52 km2 / 20 mi2). Iron Gate 1 station's combined annual capacity is 10,89 TWh (5,24 TWh Romanian + 5,65 TWh Serbian). Iron Gate 2 station's combined annual capacity is 2,61 TWh (1,3 TWh Romanian plus 1,31 TWh Serbian).

The Iron Gate Dam's construction started in 1964 as a joint venture between both communist countries - Romania and Yugoslavia (of which Serbia was part until 1992). When completed in 1984, the Dam's both stations had a total of 16 generators producing 432 MW (megawatt) power in total. The generated hydropower back then was equally divided between both countries.

Today, Serbia produces more power annually due to its newer (more efficient) equipment. The Serbian power station has 10 generators (total power output 270 MW) producing approx 1,46 TWh per year. The Romanian power station has 10 generators (total installed capacity 321 MW) producing approx 1,3 TWh (terawatt-hours) per year.

Currently, the Iron Gate powerplant's total generation capacity is 591 MW.
