The invention relates to the field of turbomachines and more specifically to a device (13) and to a method for temporarily increasing the power of at least one first turbomachine (5A). This device (13) comprises a tank (14) of liquid coolant and a first injection circuit (16A) connected to said tank (14) and opening onto at least one injection nozzle (22) that can be installed upstream of at least one compressor stage (8) of the first turbomachine (5A). This first injection circuit (16A) comprises at least a first switchover valve (23) configured to open when an overpressure crosses a predetermined threshold with respect to a pressure downstream of at least one compressor stage (8) of a second turbomachine (5B) so as to allow the liquid coolant to flow to the said injection nozzle (22) of the first injection circuit (16A).
