Orkhevi (settlement in Tbilisi)

Tetrikhevi (Georgian: თეთრიხევი) is a settlement and suburb within the Samgori District of Tbilisi, Georgia. Located in the eastern part of the city, north of the Orkhevi settlement on the Samgori Plain, it was founded in the early 1950s as a community for the builders and workers of the Samgori irrigation system and its associated hydroelectric power station.

Tetrikhevhesi (Georgian: თეთრიხევჰესი, pronounced [tʰɛtʰɾixɛvhɛsi]) is the common name for the Tetrikhevi Hydroelectric Power Plant Settlement (Georgian: თეთრიხევის ჰესის დასახლება, pronounced [tʰɛtʰɾixɛvis hɛsis dasaxlɛba] ), a settlement (dasakhleba) and suburb in the Samgori District of Tbilisi, Georgia. Located in the eastern part of the city, it lies north of the Orkhevi settlement and west of the Tetrikhevi settlement, on the Samgori Plain. It was founded in the early 1950s as a workers' settlement for the builders and staff of the eponymous hydroelectric power plant, a part of the Samgori irrigation system cascade. The history and daily life of the settlement are inextricably linked to the operation of this HPP, which has shaped its unique character over the decades. The settlement's name, a portmanteau toponym, is derived from the hydronym Tetri-Khevi (Georgian for "White Ravine") and the acronym "HPP". Historical sources emphasize the need to distinguish it from the neighboring settlement of Tetrikhevi, with which it was often confused, leading to domestic mix-ups recorded in the press. During the Soviet period, Tetrikhevhesi was built by the Gruzgidrostroy trust on previously undeveloped land and quickly became a well-maintained "green oasis." With the dissolution of the Soviet Union, the settlement underwent economic transformations, highlighted by the privatization of its core enterprise, the HPP. In the post-Soviet era, residents faced both the typical hardships of the period and new challenges, including environmental risks associated with its proximity to a mudflow-prone ravine. Today, Tetrikhevhesi remains a residential area whose infrastructure is closely tied to the power plant that gave it life.

Tetrikhevi Hydroelectric Power Station (Georgian: თეთრიხევის ჰესი) is a hydroelectric power station in Georgia, the third and final stage of the Samgori cascade, located on the Upper Samgori Main Canal on the eastern outskirts of Tbilisi in the settlement of Tetrikhevhesi. It is a key element of the Samgori irrigation and energy system, created in the post-war years to irrigate arid lands and generate electricity. The station is also notable for its status as an active training and laboratory base for power engineering students from the Georgian Technical University. Construction of the station was carried out as part of the "people's construction" of the Samgori system starting in 1947; the Tetrikhevi HPP was put into permanent operation in 1955. In 1995, the station was privatized by its workforce, which enabled its rehabilitation and a significant increase in electricity generation. The current owner is Georgian Water and Power. By design, it is a diversionary, canal-type HPP. The installed capacity of the station is 13.6 MW. The powerhouse contains two hydro-units with Francis turbines, operating at a design head of approximately 110 meters. A distinctive feature of the Tetrikhevi HPP's operation, like the entire cascade, is its seasonal regime: during the winter, the station generates peak electricity by transferring water from the Sioni Reservoir to the Tbilisi Reservoir, while in the summer, the stored water is used for irrigation.
