The Eisernes Tor 1 power plant ( Serbian Ђердап I Đerdap I ; Roman. Porţile de Fier I ) is the most powerful run-of- river power plant in the Danube with 2280 megawatts .

location

It is located on the border between Serbia and Romania at the Iron Gate as the penultimate Danube power plant in front of the Danube Delta and the Black Sea , only followed by the Iron Gate 2 power plant .

technology

The power plant output of 2280 megawatts is made up of the 190 MW nominal output of the twelve vertically arranged Kaplan turbines with a diameter of 9.5 meters. The power plants arranged along the dam wall form a structure more than a kilometer long across the river. Between the two machine houses there is a gravity dam consisting of 14 fields, each 25 meters wide, with double hook gates to regulate the water level. The standard energy capacity of the Romanian side is 5.4 TWh per year, the Serbian power plant side comes to 5.65 TWh despite the small bottleneck capacity (as of 2010). The two-stage lock Đjerdap was built for shipping and repaired in 2006–2008.

history

The planning of a power plant, for which a dam with a reservoir first had to be built, began in 1964. Both neighboring countries participated equally in the work, as the energy generated should also be shared. The flooding began in 1968, the backwater created the 150 kilometer long Djerdapsee . Several villages and islands sank in the floods and with Cetatea Tricule also a former castle. The water level rose permanently by 35 meters. In addition to generating energy, the waterway on the Danube has also been expanded and the passage of ships has been made easier by means of appropriate locks.

At the time of completion in 1972, the Eisernes Tor 1 power plant was the world's largest river power plant with a bottleneck capacity of 2,052  MW . In 1999, what was then Sulzer Hydro, and since 2009 Andritz Hydro , began renovating the Romanian part of the power plant, increasing the bottleneck output of the six generators from 171 MW each to 194.4 MW, bringing the total power plant output to 2,192 MW increased. The renovation of the Serbian part of the power plant in cooperation with the Ryazan mechanical engineering company (Russian: Рязанский станкостроительный завод ) began in July 2008 and was completed by the end of 2010.

ecology

The two parts of the power plant together with the corresponding locks form an insurmountable obstacle for fish, especially the sturgeon that come from the sea to spawn in the Danube.
