Slovenské elektrárne, a.s., is primarily a nuclear generating company with four units in operation and two other units under construction. The share of nuclear generation on its own gross production reaches almost 80%. Its two nuclear sites are in Jaslovské Bohunice and Mochovce.
The Mochovce Nuclear Power Plant located in southern Slovakia between the towns of Nitra and Levice hosts two units in operation and two under construction. The two operating units 1 and 2 were commissioned 1998 and 2000 and with the current combined installed capacity of 940 MWe generate over 7,5 TWh of electricity annually, more than a quarter of electricity consumption in Slovakia. Water required for cooling is taken from a water dam built on the nearby Hron river, which ensures sufficient supply of water even in very dry climate conditions.
Units 3 and 4 of the Mochovce Power Plant are currently under construction, which was restarted in 2008 following a suspension in 1990’s due to lack of funding. The project is the largest private investment in Slovakia, and one of three nuclear power plant constructions in Europe. With over 5,000 workers on site, and more than 55 million man-hours worked by mid-2016, the project contributes significantly to the economic growth of Slovakia. The construction already incorporates a large number of unique safety upgrades, including state-of-the-art control room, and upon completion should rank among the most modern and safest power plants in the world. With more than 70% of contractors from Slovakia and the Czech Republic, the project draws from capabilities and know-how of regional experts. It is expected that the initial capacity of 471 MWe per unit will be increased up to 535 MWe in the future.
