Giz Galasi Dam
History
The main goals of building the Giz Galasi Dam were hydroelectric power production and irrigation. The project was developed with the agreement between the Soviet Union and Iran in October 1977. The project was completed in 1982.
In 1993, the area where the dam was to be built was occupied by the Republic of Nagorno-Karabakh.
Between 28 June and 2 July 1994, during the first official visit of the President of Azerbaijan Heydar Aliyev to Iran, a memorandum on the implementation of the project was signed.
In February 2016, the governments of Azerbaijan and Iran signed an agreement on cooperation in the field of construction, operation, use of energy and water resources of the Khoda Afarin and the Giz Galasi reservoirs.
On 18 October 2020, Azerbaijan returned control over its side of the dam.
On 19 May 2024, President of Azerbaijan Ilham Aliyev and President of Iran Ebrahim Raisi met at the site of the Giz Galasi hydroelectric complex to inaugurate it, in addition to commissioning the Khoda Afarin hydroelectric complex. Later that day Raisi and other high-ranking Iranian officials died in a helicopter crash on their way to Tabriz.
