The Paatsjoki River hydroelectric power plants are a series of hydroelectric installations on the Paatsjoki River.
The Paatsjoki River flows from Lake Inari in Finland and for most of its duration, it marks the border between Russia and Norway. On the river there are several Norwegian and Russian hydroelectric stations. The operations of the stations is governed by several international agreements (Agreement between the Soviet Union and Norway on 18 December 1957 about the usage of hydroelectric installations on the Paatsjoki River, Agreement from 29.04.59 about regulating the control of Lake Inari concerning hydroelectric installations and the Kaitakoski Dam between the Soviet Union, Finland, and Norway.) About 85% of the electricity produced by the series of Russian hydroelectric stations is exported abroad. The hydroelectric system operates automatically.
The Russian hydroelectric installations belong to Territorial Generating Company № 1, based in Saint-Petersburg, Russia.
Hydroelectric stations Kaitakoski (Russia), Jäniskoski (Russia), Rajakoski (Russia), Hevoskoski (Russia), Skogfoss (Norway), Melkefoss (Norway), Borisoglebskaya (Russia) form the series of hydroelectric installations on the river.
In total, all the hydroelectric stations have a power of 275.9 Megawatts, and produce 1475 GWh per year.
The list is in downstream order, from Lake Inari to the Barents Sea.
The Kaitakoski hydroelectric station (Russian: Кайтакоски ГЭС (ГЭС-4)) in Russia on the Paatsjoki River (68°56′19″N 28°36′02″E / 68.93861°N 28.60056°E) began operation in 1959. The power station is owned and operated by TGC-1 power company. At the uppermost three stations, the river is entirely in Russia.
