Kyiv Hydroelectric Station (Ukrainian: Київська [[wikt:ГЕС|ГЕС]]|Kyivska HES) is a run-of-river power plant on the Dnieper River in Vyshhorod, Kyiv Oblast, Central Ukraine. The 288m (945feet) long dam creates the Kyiv Reservoir with the purpose of hydroelectric power generation and navigability with the dam's associated lock. The first of 20 generators in the power station was commissioned in 1964, and the last in 1968. Together with the Kyiv Pumped Storage Power Station, it creates a hydroelectricity generating complex. It is operated by the Ukrhydroenergo. Turbines for the plant were produced by the Kharkiv Factory Turboatom, and generators by the Kharkiv Factory "Elektrovazhmash".
The Kyiv Hydroelectric Power Plant project was developed by the leading project research institute "UkrHydroProekt". Construction of the Kyiv Hydroelectric Power Plant began in October 1960. Construction was carried out by Kremenchugs'bud Trust collective. During the construction, many new organizational and constructive solutions were introduced. In particular, the reduction of the cost of construction, and reducing its term when improving the quality of construction structures, was achieved thanks to the use of prefabricated reinforced concrete. The Kyiv HPP also introduced new technologies for high-frequency installation of large concrete constructions for the first time.

During the construction of the Kyiv Hydroelectric Power Plant, groundworks were carried out in an amount of 79 400 thousand cubic meters; 825 thousand cubic meters of monolithic concrete was made.
For the first time in the former USSR, in Kyiv HPP low-pressure horizontal capsule hydro units were used.
The Kyiv hydroelectric plant is unique in that for the first time in the practice of domestic hydro-building the hydroelectric power plant was combined with a concrete spillway dam with 20 waterways.
Hydroelectric power station - 51 m wide and 285 m long connected type, structurally divided by temperature-sediment seams into five blocks with 4 horizontal capsule units in each.
The water reservoir of Kyiv hydroelectric power station - channel, river type, with limited seasonal regulation. The total length of the protective structures is 70 km; the highest elevation of the channel dam is 22 m.
The structure of the main hydroelectric power plants includes: a hydroelectric power plant with right and left bank facilities, an open distribution unit (GRP) of 110 kV, and a combined concrete spillway with 20 waterways. The hydro-unit also includes the right-bank and left-bank dam, the protective dam of the right bank, the dam - the insert between the gateway and the building of the hydroelectric power station, the dam-wave separation, channel rowing and pressureless dam of the left bank and the Kyiv navigable gateway (which today belongs to the State Enterprise "Ukrvodshlyah").
In general, at the hydroelectric power station, 20 horizontally-capsule aggregates with rotary-shovel hydro turbines type PL/GK-600M manufactured by the Kharkiv turbine plant and horizontal synchronous generators of type SGK-538/160-70 were installed at the plant "Electrotyazhmash", installed capacity for today (after carrying out of the reconstruction of hydrounits) is 440 MW.
Over the overlap of the flowing part in the generating premises are located: the main outputs of generators, oil pressure equipment with speed regulators, pumps, and the like.
The upper ceiling of these premises in a complex with a deformed metallic lid forms the threshold of spillage. From the bottom seating along the entire surface of the building.
On February 24, 2022, during the Russian invasion of Ukraine, Andrii Valeriiovych Nikonchuk died defending the Kyiv Hydroelectric Power Plant from Russian air raids.[2]
