Claim 10:
11. A method comprising:
receiving an amount of electricity from a power generation plant;
operating a pumped-heat energy storage (“PHES”) system in a charge mode consuming a first amount of the received amount of electricity during conversion of at least a portion of the received electricity into stored thermal energy in a hot thermal storage (“HTS”) medium by transferring heat from a working fluid to a warm HTS medium, resulting in the hot HTS medium;
reducing a power level of the PHES system such that it consumes a second amount of the received amount of electricity that is lower than the first amount; and
heating the hot HTS medium with an electric heater while the power generation plant is in a generation mode by consuming at least a third amount of the received amount of electricity.
