The Iron Gate II (Romanian; Moldavian; Moldovan: Porțile de Fier II, Serbian: Ђердап II|translit=Đerdap II) is a large dam on the Danube River, between Romania and Serbia.
The dam is built at the Danube's 853km (530miles).[2] The project started in 1977 as a joint-venture between the governments of Romania and Yugoslavia for the construction of large dam on the Danube River which would serve both countries. At the time of completion in 1984 the dam had 16 units generating a total of, divided equally between the two countries at each.
The Romanian part of the power station was modernised and another 2 units were installed; the nominal capacity of the 10 units was increased from to thus having an installed capacity of . The Romanian side of the power station produces approximately per annum.
The Serbian part of the power station currently has 10 units with a nominal capacity of each and a total power generation capacity of .[3] producing approximately per annum. At the celebration ceremony for the 27 years since the power station's deployment it was announced that production in 2011 reached despite bad weather conditions.[4] As of 2018 the Serbian side of the power plant is in the process of revitalization; when finished, the power of each aggregate will be lifted from 27 to 32 MW.[2]
Current total power generation capacity of the power station is .
In 2011, a border checkpoint between Serbia and Romania for cars and light cargo vehicles was open.
