Rolls-Royce supplies mtu emergency gensets to Osaka hyperscale data centre

7 February 2024

Rolls-Royce is supplying a total of 31 mtu diesel fuelled containerised emergency gensets, based on 20-cylinder mtu Series 4000 engines, and a complete mtu EnergetIQ control system for a hyperscale data centre near Osaka, one of the largest data centres in Japan, with a designed capacity of 45.9 MW.

According to Mordor Intelligence, Japan is one of the fastest growing digital content delivery markets in Asia, driven by the increasing use of mobile devices and the adoption of cloud technologies.

The mtu containers contain the diesel engine with generator, plus switchgear – including the mtu EnergetIQ control and monitoring system. The fully redundant mtu EnergetIQ Manager used in Osaka monitors both the incoming grid connections and the status of all generators within the plant. It starts the emergency diesel generators in the event of a grid failure, regulates the supply of electricity to the consumers and ensures that the load is transferred back to the grid and the generators are stopped when the grid is stable again. The mtu EnergetIQ Manager is part of the new mtu automation ecosystem mtu EnergetIQ. It can control groups of power generation and storage facilities, as well as power distribution from generation to consumer.

Rolls-Royce says it is one of the three leading suppliers of emergency power systems for data centres worldwide and has supplied a total capacity of approximately 5 GWe of emergency generators to the global data centre market.
