Abstract

A water electrolysis system and a method for operating the water electrolysis system, capable of providing an adjustment capacity solely by controlling an amount of water supply are provided. A water electrolysis system which applies grid power to a plurality of water electrolysis stacks via a rectifier to provide hydrogen gas and oxygen gas as generated gas from water, and adjusts a power consumption in accordance with a command of a provision of an adjustment capacity. Upon reception of the command of the provision of the adjustment capacity in a contract timeframe in which the provision of the adjustment capacity is contracted, an amount of water supplied to the water electrolysis stack, temperature and pressure of the water electrolysis stack are made controllable in accordance with an amount of power derived from adding an amount of power for the adjustment capacity to be provided to an amount of power consumption of the water electrolysis stacks.
