Kakhovskaya HPP named after. P.S. Neporozh­niy is part of the Dnieper cas­cade of six hydro­elec­tric pow­er sta­tions. Com­plet­ed by the mid-1970s, the cas­cade of hydro­elec­tric pow­er sta­tions on the Dnieper (Kyiv, Kanevskaya, Kre­menchugskaya, Dne­prodz­erzhin­skaya, Dnieper and Kakhovskaya) and large reser­voirs with it made it pos­si­ble to car­ry out annu­al reg­u­la­tion of the Dnieper flow, to use it for pow­er sup­ply, water trans­port, and irri­ga­tion of lands in the south of the Ukrain­ian SSR ( now Ukraine) and the north­ern part of the Crimean Penin­su­la, improve water sup­ply to the indus­tri­al areas of Krivoy Rog and Don­bass.

Kakhovskaya HPP is the sixth, low­er stage of the Dnieper cas­cade.

The decree on the con­struc­tion of the sta­tion was adopt­ed on Sep­tem­ber 20, 1950. Coun­cil of Min­is­ters of the USSR. The hydro­elec­tric com­plex was erect­ed in 1950–1956 by the spe­cial con­struc­tion and instal­la­tion depart­ment “Dne­prostroy”. The first of six tur­bines was installed on Octo­ber 18, 1955. The hydro­elec­tric pow­er sta­tion with an installed capac­i­ty of 312 MW was put into com­mer­cial oper­a­tion on Octo­ber 19, 1959. New Kakhov­ka was formed on the site of the vil­lage of Klyuchevoe with the start of con­struc­tion of the sta­tion, and in 1952 it received the sta­tus of a city.

As a result of the con­struc­tion of the Kakhov­ka hydro­elec­tric pow­er sta­tion, the water lev­el of the Dnieper in 1955–1958 formed the Kakhov­ka reser­voir. Res­i­dents of sev­er­al dozen set­tle­ments were reset­tled from the flood­ed area — about 37 thou­sand peo­ple in total.

In 1979, the North Crimean Canal was put into oper­a­tion, through which water from the reser­voir flowed into the low-water and arid ter­ri­to­ries of the Kher­son and Crimean regions of the Ukrain­ian SSR.

After the col­lapse of the Sovi­et Union in Ukraine dur­ing the 1990–2020s, repair, recon­struc­tion and renew­al of hydro­elec­tric pow­er sta­tion equip­ment was car­ried out in sev­er­al stages. In par­tic­u­lar, the Tur­boatom enter­prise (Kharkov) replaced tur­bines on all six hydro­elec­tric units of the sta­tion, the installed capac­i­ty of the hydro­elec­tric pow­er sta­tion increased to 334.8 MW. Also on the ter­ri­to­ry of the sta­tion, a new san­i­tary build­ing was built, the hydraulic engi­neer­ing work­shop was restored, etc.

In 2000, the sta­tion was named after Pyotr Neporozh­ny (1910–1999), Min­is­ter of Ener­gy and Elec­tri­fi­ca­tion of the USSR in 1965–1985, cor­re­spond­ing mem­ber of the Russ­ian Acad­e­my of Sci­ences.

In Ukraine, a plan was being worked out to increase the installed capac­i­ty of the sta­tion by intro­duc­ing addi­tion­al hydraulic units — the con­struc­tion of the Kakhovskaya HPP‑2 with a capac­i­ty of 250 MW. In 2020, by order of the Cab­i­net of Min­is­ters of Ukraine, the sta­tion expan­sion project was includ­ed in the list of pri­or­i­ty invest­ment projects. As of 2022, pre­lim­i­nary sur­veys were under­way, but con­struc­tion of HPP‑2 had not begun.

In 2021, the sta­tion’s full-time work­force was 215 peo­ple. The own­er of the sta­tion was the Ukrain­ian state com­pa­ny Ukrhy­droen­er­go.

Kakhovskaya HPP is a run-of-riv­er, com­bined type, low-pres­­sure hydro­elec­tric pow­er sta­tion with rotary-blade tur­bines. It was equipped with a sin­­gle-cham­ber nav­i­ga­tion lock. A road and a rail­way passed through the sta­tion’s hydraulic struc­tures. The sta­tion includ­ed a 154 kV pow­er trans­mis­sion line.
