In the article a novel approach toward a power facility is proposed, focusing on clean electric energy generating, during peak loads of a power system (PS). In such system, the primary energy is generated in a nuclear energetic installation that, by its nature, is suitable for continuous delivery of energy at a relatively constant load. Based of this primary energy, through electrolysis, hydrogen (H) and oxygen (O) can be produced, and stocked in special reservoirs.During peak load, H and O should be recombined in a combustion process, by generating steam at very high temperature. The steam is further sent to a condensation turbine, which is generating in return second level energy that is leveling the peaks in the PS load.
