1982 - Unit 1 of VVER-1000/302 with a capacity of 1000 MW was commissioned. In December 2013, the operation of the power unit No. 1 of the South Ukrainian NPP was extended for 10 years.

1985 - VVER-1000/338 unit 2 with a capacity of 1000 MW was commissioned. In December 2015, the operation of the power unit No. 2 of the PNPP was extended for 10 years.

1989 - the 3rd unit of VVER-1000/320 with a capacity of 1000 MW was commissioned. In December 2019, the operation of power unit No.3 of the PNPP was extended for 10 years.
(EO license No. 00000064).

1999 - Aleksandrovskaya HPP with an installed capacity of 25 MW was commissioned. Two hydraulic units are in operation at OlHPP.

1981 - construction of the Tashlyk PSPP with a total capacity of 3000 MW was started;

2006 - the first hydroelectric unit of the Tashlyk PSPP was commissioned;

2007 - the second hydraulic unit of the Tashlyk PSPP was commissioned;

2021 - the first test run of the third power unit of the Tashlyk PSP was carried out.

The operation of the 3rd hydropower unit creates new opportunities for balancing and more efficient operation of the domestic nuclear generation, which is especially important during winter peak loads.

On June 14, 2012, Tashlyk PSP produced its first billion kilowatt-hours since the start of generation. The power complex generates about 17-20 billion kW of electricity annually. It is the only energy enterprise in Ukraine that uses basic nuclear, maneuverable hydro and pumped storage capacities in a comprehensive manner. South Ukrainian NPP is a pioneer among domestic nuclear power plants in diversifying nuclear fuel supply sources. For the first time in Ukraine, fresh nuclear fuel produced by the American company Westinghouse was loaded at the plant, which started Ukraine's successful path to diversifying nuclear fuel supplies. Since 2018, power unit No. 3, and since 2020, power unit No. 2 of the plant have been operating exclusively on Westinghouse fuel.
