1. A system (200), comprising:
a first gas turbine (GT) system (210R) operatively coupled to a first generator (212) to generate a baseload power (260), wherein a first portion (237) of the baseload power (260) generated by the first GT system (210R) is transmitted to a wide-area electric grid (204) controlled by a transmission system operator, (TSO) (239);
a second GT system (220) operatively coupled to a second generator (214) to generate power (262) for transmission to the wide-area electric grid (204);
wherein the system (200) further includes:
a hydrogen-producing electrolyzer (242) operatively coupled to deliver hydrogen fuel (244) to one or both of the first GT system (210R) and the second GT system (220), the hydrogen-producing electrolyzer (242) configured to be selectively powered by either a second portion (246) of the baseload power (260) generated by the first GT system (210R); and
a controller (238) configured to:
in response to a demand for power (262) from the TSO (239) not exceeding a threshold, instruct that the second portion (246) of the baseload power (260) generated by the first GT system (210R) be transmitted to the hydrogen-producing electrolyzer (242) to generate hydrogen fuel (244) for one or both of the first GT system (210R) and the second GT system (220); and
in response to the demand for power (262) from the TSO (239) exceeding the threshold, instruct that a third portion (240) of the baseload power (260) generated by the first GT system (210R) be transmitted to the wide-area electric grid (204), stopping, if not already stopped, supply of hydrogen fuel (244) to at least the second GT system (220), and turning off, if not off, the hydrogen-producing electrolyzer (242).
