A method performed by a control unit for controlling flooding of at least part of an energy storage space. The energy storage space comprises at least one Energy Storage System, ESS. The control unit detects that a critical condition associated with the at least one ESS is present. When the critical condition has been detected, the control unit initiates flooding of at least part of the energy storage space with a fluid from a reservoir. The control unit controls the flooding of the energy storage space such that the at least one ESS is submersed to a submersion level where the critical condition is no longer present.
