In the charge mode, the one or more electrochemical cells may reduce metal from an oxidized state to a zero valence state with a first electric current applied across the one or more electrochemical cells. In the discharge mode, the one or more electrochemical cells may oxidize at least some of the metal from the zero valence state to the oxidized state to generate a second electric current, oppositely charged relative to the first electric current, to generate electricity (e.g., for delivery to the grid). Operation of the one or more electrochemical cells of the electrowinning plant may be selectively changed between the charge mode and the discharge mode based on, for example, availability/cost of electricity from the grid.
