A cryogenic process of supplying oxygen to a power generation plant including at least an air separation unit ( 9,11 ), a liquid oxygen tank ( 15 ) and an air derived component liquid tank ( 17 ), comprises: During a first period: feeding a first air stream to the air separation unit at a first flowrate, feeding liquid oxygen from the liquid oxygen tank to the air separation unit, recovering a gaseous oxygen stream with a higher flow than the liquid oxygen stream from the air separation unit, sending at least one air derived component liquid to at least one air derived component liquid tank. During a second period: feeding the at least one air derived component liquid stream from the at least one air component liquid tank to the air separation unit, extracting a liquid oxygen stream from the air separation unit to the liquid oxygen tank, recovering a gaseous oxygen stream from the air separation unit and increasing the flowrate of the first air stream, feeding the air separation unit to a value greater than the first flowrate.
