Worldwide Independent Power (WiP): How To Save Energy In Data Centres

We share some top tips on how to save energy in data centres using efficient, modern modular UPS.

With the number of interconnected devices set to top 50 billion by 2020, data centres will face increased demand for storage and processing capacity. But UK facilities already consume nearly 3 TWh of power a year. They can’t just burn more electricity to meet these growing needs.

To start with, Chris explains just how a data centre uses power at present. Energy costs can make up to 60% of a site’s total overheads. For a hyperscale data centre that can mean electricity bills of more than £3 million a year.

The article moves on to discuss some of the metrics used to measure the efficiency (or otherwise) of data centres. Although the most recognisable measuring stick, Power Usage Effectiveness (PUE) has its drawbacks. It doesn’t take into account climate differences. While many critics argue it’s been hijacked as something of a meaningless marketing tool.

Help is at hand though, in the technological advances being made in the uninterruptible power supplies sector. Chris explains how the rise of modular UPS is leading to significant energy savings across server rooms.

He highlights Riello UPS’s recent win at the DCS Awards 2018 as evidence of how to save energy in data centres. Upgrading critical power protection to our Multi Power UPS delivered a 72% reduction in carbon emissions. The client also saved 1.25 million kWh of energy – enough to power 316 houses for a year – and cut its annual electricity bill by £335,000.

Other significant savings achieved by the move to modular include reducing energy-intensive air conditioning by 71.81%. In addition, the project also delivered a 59% per m2 reduction in footprint.
