Energy storage unit for peak load coverage and/or outage reserve in steam power stations, comprises a steam generating unit, a steam turbine and a storage vessel with steam and water chambers. The water chamber or the vessel is connected to a single or multi stage secondary steam generating unit, which on the steam side, is connected to the turbine via a steam delivery pipe, and, on the water side, via a hot water return pipe to the feed water pipe and/or to a compensating vessel. The steam chamber is connected via a steam pipe at a point in the main cycle upstream from the inlet point of the live steam pipe.
