In case of absence of the electrical power for time intervals greater than ten minutes, during which the power supply to the DataCenter is ensured by the UPS system, the ReCaS DataCenter is fed by an auxiliary generator, Green Power GP 1650, capable of providing 1500 kVA in continuous operations, and 1650 kVA for short periods. The size of the generator can be guessed by comparing with that of the bus in transit in via Omodeo.
