Inguri Dam

The Inguri Dam is a hydroelectric dam on the Inguri River in Georgia. Currently it is the world's highest concrete arch dam with a height of 272 metres (890 ft).[1][2][3] It is located north of the town Jvari. It is part of the Inguri hydroelectric power station (HES) which is partially located in the partially recognised Abkhazia.

[edit] History

Construction of the Inguri dam began in 1961. The dam became temporarily operational in 1978, and was completed in 1987. In 1994, the dam was inspected by engineers of Hydro-Québec, who found that the dam was "in a rare state of dilapidation".[4] In 1999, the European Commission granted €9.4 million to Georgia for urgent repairs at the EInguri HES, including replacing the stoplog at the arch dam on the Georgian side and, refurbishing one of the five generators of the power station at the Abkhaz side.[5] In total, €116 million loans were granted by the EBRD, the European Union, the Japanese Government, KfW and Government of Georgia.[1]

[edit] Technical features

The Inguri hydroelectric power station (HES) is a cascade of hydroelectric facilities including, in addition to the dam - diversion installation of the Inguri HES proper, the near-dam installation of the Perepad HES-1 and three similar channel installations of the Perepad HESs-2, -3, and -4 located on the tailrace emptying into the Black Sea.[6] While the arch dam is located on the Georgian controlled territory in Upper Svanetia, the power station is located in the Gal district of Abkhazia.[5] Inguri HES has 20 turbines with a nominal capacity of 66 MW each[7], resulting in a total capacity of 1,320 MW. Its average annual capacity is 3.8 billion kW/h, which is approximately 46% of the total electricity supply in Georgia as of 2007.[8]

[edit] Operation

The dam located on the Georgian side is maintained by Georgian company Enguri Ltd.[1] The power plant located on Abkhazian side is operated by state-owned Abkhazian company Chernomorenergo. According to the agreement between Georgia and Abkhazia, Georgia receives 60% of produced electricity, while 40% is consumed in Abkhazia and in Southern part of Russia.[9] In September 2008, the President of Abkhazia, Sergei Bagapsh, announced that Abkhazia will revise this deal while foreign minister Sergey Shamba said that Abkhazia is not calling for any revision of the power distribution balance at the moment.[9]
