The Enguri Dam is a

Enguri River in Tsalenjikha, Georgia. Currently, it is the world's second highest concrete arch dam, with a height of 271.5 metres (891 ft).[1][2][3] It is located north of the town of Jvari. It is part of the Enguri hydroelectric power station (HES) which is partially located in Abkhazia
.

History

Bzyb River as his favourite resort was located near the mouth of the river at Pitsunda. However, his experts informed him that a dam built on the Bzyb River would have had catastrophic effects in causing beach erosion at Pitsunda, so in the end the dam was built on the Enguri River instead, where the impact upon the coastline was assessed to be considerably less pronounced.[4]

Construction of the Enguri 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

EBRD, the European Union, the Japanese Government, KfW and Government of Georgia.[1] In 2011 the European Investment Bank (EIB) loaned €20 million in order to complete the rehabilitation of the Enguri hydropower plant and to ensure safe water evacuation towards the Black Sea at the Vardnili hydropower cascade.[7]

In the early 1980's, a series of radio relays were built to connect the Enguri Dam with the Hudoni Dam, which was under construction. The relays were in remote territory with no access to electricity, and thus were powered with a series of eight radioisotope thermoelectric generators (RTGs). However, the Hudoni dam's construction was stopped as Georgian independence from the Soviet Union drew near. The stations and their RTGs were abandoned and eventually dismantled. The RTG's became lost at this time. Two were rediscovered in 1998, leading to no injuries. Two more were found in 1999, and again led to no injuries or significant radiation exposure. Two more were rediscovered in 2001, which led to the Lia radiological accident. The other two sources remain unaccounted for.[8]

Technical features

Distribution of the Enguri HES facilities in Abkhazia and Georgia proper.

The Enguri hydroelectric power station (HES) is a cascade of hydroelectric facilities including, in addition to the dam - diversion installation of the Enguri 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.

The facility's arched dam, located at the town of Jvari, was inscribed in the list of cultural heritage of Georgia in 2015.[14]
