NEK is equipped with a Westinghouse Pressurised Light Water Reactor of 2.000 MW thermal power. The power plant's net electrical power is 696 MW. It is connected to the 400kV grid supplying power to consumer centres in Slovenia and Croatia.
NEK generates over five billion (109) kWh of electrical energy per year, which represents approximately 40% of the total electricity produced in Slovenia.
Thanks to its operating characteristics, NEK covers the base load throughout the year. Additionally, as a reliable source of active and reactive power, it is an important supporting point of the electricity supply system as part of the European Network of Transmission System Operators for Electricity (ENTSO-E). It is a significant factor in the stabilisation of critical operating and voltage conditions, especially in the case of large transients within the ENTSO-E.
The operation of the power plant between two outages is called a fuel cycle. During an outage, part of the spent fuel is replaced with fresh fuel, preventive equipment overhauls are carried out and parts are replaced, the integrity of material is checked, surveillance tests are carried out and corrective measures are taken as needed. The twenty-eight fuel cycle, which began with the connection of the power plant to the grid on 17 May 2015, will last for eighteen months. This is the operational orientation of the power plant for the future.
