Standby power for PEER 1 Hosting’s greenest data centre

Fri, 11/16/2012 - 17:36 -- Ruth Williams

3-10Finning Power Systems has supplied a bespoke, standby diesel genset package for one of the UK’s newest and greenest data centres, operated by PEER 1 Hosting, to ensure complete power continuity in the event of mains power failure.

Housed in Building 5000 within the Langstone Technology Park campus, the data centre should be one of the most energy?efficient of its kind in the UK. This design is expected to achieve a power usage effectiveness rating (PUE) of 1.1. 

The infrastructure is already in place to eventually offer 10 MVA of available power and more than 5 000 m2 of available server racks. The data centre features a wide range of energy-saving technologies, such as all year free air cooling, heat recovery and lighting motion sensors to help reduce power consumption and achieve the PUE. 

Finning supplied two Cat 3516BHD, 2500 kVA-rated, standby diesel gensets, together with two 26 050 litre structural fuel tanks; working to a four?month timeframe from first contact to final commissioning.

The centre is built using a modular ‘POD’ system, each with its own discrete electrical room to give customers flexibility in their use of space. There is one POD currently operational and a further three pods will be provisioned as capacity grows, which will require a further three Finning gensets.

The existing pair of generators is configured in an N+1 arrangement, with one set providing up to 2 MW of standby power and one acting as a swing unit, providing redundancy in case the primary unit fails.
