Due to all upgrades in past decades NEK produces one TWh more electrical energy

Through optimisation of fuel cycle and constant improvement to organisational and work processes, constant training and technological upgrades, in last decades NEK on average increased its production from 4.5 TWh to 5.6 TWh per year. As a comparison, this is more than what all hydro plants on the Sava river produce in one year.
