How does the Iron Gate project produce electricity and improve navigation?

The Iron Gate project, a joint development between Romania and the former Yugoslavia completed in 1972, utilizes a large dam and hydroelectric power plant to harness the energy of the Danube River. This facility provides significant energy to both bordering nations.12

Regarding navigation, the project transformed one of the most dangerous and difficult stretches of the river into a reliable waterway. By damming the Iron Gate rapids and incorporating two locks—each featuring two chambers—the project facilitates the passage of vessels through the gorge. These improvements have had a profound impact on river traffic, quadrupling the annual tonnage of shipping and reducing the journey time for vessels traveling from Black Sea ports to Belgrade, Vienna, and central Europe from approximately 100 hours to just 15 hours.321
