Baudouin 20M33 PowerKit Engines for Data Centre Critical Power
In 2024, ENI, a global energy leader, expanded its Green Data Centre in Northern Italy to host a new high-performance supercomputing system. Designed around innovative concepts, the facility is one of the most energy-efficient data centres in the world, with a certified PUE below 1.2.
To safeguard this critical HPC facility from mains power outages, OEM partner Margen S.p.A. designed and delivered a robust emergency power system, with Baudouin selected as the engine supplier.
The installation consists of five containerized, soundproof diesel generator units, each equipped with a Baudouin 20M33 PowerKit engine. Together, these five units provide 13.5 MVA of standby power capacity, enough to support the data centre’s full electrical load with N+1 redundancy.
The HPC6 supercomputer alone can draw more than 10 MVA at peak load, so the backup system was sized to comfortably handle the demand while keeping one genset as a spare. The result is a highly reliable power infrastructure designed to ensure uninterrupted operation of ENI’s mission-critical data centre, even in emergency scenarios.
Each of the five generator sets is powered by a Baudouin 20M33G2500/5 PowerKit engine: a 20-cylinder, 65.4-litre V-type turbocharged diesel engine with high-pressure common-rail fuel injection.
This engine is rated for up to 2,750 kVA of standby electrical output. In the ENI data centre project, the engines are integrated into fully self-contained power modules.
Margen engineered these modules with onboard step-up transformers installed inside each container, allowing the system to deliver 20 kV medium-voltage output directly to the facility’s electrical distribution. This design enables the gensets to feed the data centre’s power system without external transformer yards, reducing footprint and installation complexity.
The generator units are housed in specialized sound-attenuated enclosures to meet strict noise level requirements, given the proximity to operational areas.
The system is configured for automatic start and fast load acceptance. If a grid outage occurs, the gensets can ramp up and synchronize quickly, supplying stable power to the HPC servers and cooling systems within seconds.
The overall power architecture, with five identical genset units, provides both the capacity and the redundancy required for 24/7 uptime of ENI’s HPC data centre.
The success of this project highlights several key advantages of Baudouin’s PowerKit engine solutions.
The 20M33 engines deliver very high power density, allowing Margen to package five 2.7 MVA generators into containerized units with relative ease. This compact, modular design simplified transportation, on-site installation and future scalability of the backup system.
Baudouin’s PowerKit DCP engines are specifically engineered to meet the stringent demands of modern data centres.
Key features include a comprehensive product range from 590 to 3300 kVA, a robust and reliable design for secure power provision, dual starter options for increased redundancy, high transient and block load capabilities, and a market-leading warranty offering two years of coverage with unlimited working hours.
These features make Baudouin’s PowerKit DCP engines an ideal choice for data-critical backup power, helping facilities such as ENI’s Green Data Centre maintain uninterrupted operations.
