Rolls-Royce is supplying 31 mtu generator-sets and a microgrid-level control system to support emergency operations at a new, hyperscale data center in Japan.
The data center went into operation near Osaka earlier this year. It has a designed capacity of 45.9 MW.
Rolls-Royce’s delivery includes the emergency mtu gen-sets and a complete mtu EnergetlQ control system package. The company’s group has installed eight of those gen-sets, based on the 20-cylinder mtu Series 4000 Tier-4 diesel-fired engines, all housed in a container with generator and switchgear and control and monitoring technologies.
The company will add additional gen-sets as the new data center’s capacity increases.
The EnergetIQ control systems provide automation and monitoring for distributed energy and microgrid resources. It monitors both incoming grid connections and generator status within the plant, according to Rolls-Royce.
The control system will start the emergency diesel generators in the event of a grid failure.
Rolls-Royce's press release did not name the data center customer for the backup power system. Companies which have built new data centers in Osaka over the past two years include ESR, Colt DCS, AirTrunk, Stack Infrastructure, Dimension Data and GLP, among others.
ResearchandMarkets two years ago predicted that the Japan data center market would grow 7 percent annually to US$10 billion by 2026.
Osaka Prefecture has a combined population of more than 8 million people and boast a gross domestic product equivalent to about US$45,000 per capita annually, according to reports. The area is home to more than a dozen data center facilities.
Germany-based Rolls-Royce Power Systems operates in more than 150 countries and employs close to 10,000 people worldwide. It has supplied approximately 5 GW of emergency generators to the global data center market.
