Abstract
Abstract A method and system is described which employs a thermal energy accumulator in which a thermal energy fluid and hot water coexist with each other. Hot water is taken out of the accumulator and supplied as thermal energy to an energy utilization compound arrangement of a total flow turbine and a steam turbine driving an electric power generator. The thermal energy fluid may be in the form of saturated steam, for example.
