1. An apparatus comprising:
a thermal storage assemblage including a plurality of thermal storage blocks, wherein at least some of the thermal storage blocks include multiple fluid flow slots, wherein at least some of the fluid flow slots are configured to define fluid pathways through the thermal storage blocks;
a plurality of heater elements positioned within the thermal storage assemblage, wherein each of the plurality of heater elements is configured to heat at least one of the thermal storage blocks;
a fluid movement system configured to direct a stream of a first fluid through the fluid pathways to heat the first fluid to a specified temperature range;
a first steam generator configured to, using the first fluid, convert input feed water into input steam;
a steam turbine configured to cause generation of electricity using the input steam; and
a preheater configured to, using waste heat from the steam turbine, preheat feed water provided to a second steam generator.
