Data Centres
Diesel generators for data centres: UPS-compatible, redundant (N+1, 2N) and synchronized systems, containerised solutions and long-duration fuel planning.
In data centres, servers, storage and network equipment and cooling systems must run on uninterrupted power. When the mains fails, a data centre generator comes online before the UPS batteries run out and supplies these loads for the duration of the outage.
What matters in a data centre?
- UPS compatibility: The generator must be specified with an alternator and regulator suited to the UPS’s non-linear load characteristics and harmonics.
- Redundancy: In an N+1 or 2N architecture, several generators run in parallel via a synchronization panel, so capacity is maintained even during maintenance or a fault.
- Load steps: Chillers and UPS charging currents create sudden load steps; the generator must accept these steps without a dip in voltage or frequency.
- Fuel and runtime: The fuel tank and day tank system are planned around the target runtime. You can estimate fuel consumption with our fuel consumption calculator.
- Space and noise: Containerised solutions allow fast installation on a roof or on site, with good sound insulation.
Data centre projects with Terex Diesel
With our high-power canopied and containerised sets, synchronization panels and medium voltage solutions, we build the redundant architecture a data centre needs. Every set passes a full-load test at our facility, and our commissioning and scheduled maintenance teams stay by your side after installation.

Frequently asked questions
Why does a data centre need a generator if it already has a UPS?
The UPS carries the load for the first seconds and minutes of an outage, but battery autonomy is limited. The generator comes online during this window, while the UPS bridges the gap, and supplies the data centre however long the outage lasts.
What do N+1 and 2N mean in a data centre?
N is the number of generators needed to carry the load. N+1 adds one standby generator; with 2N, the entire system is built as two independent paths. The choice depends on the availability level the data centre is targeting.
