The winter electricity outlook: Will the data centre sector weather another energy crisis

Prior to last winter the media made dire forecasts of the potential for electricity blackouts in Great Britain, which of course didn’t materialise. They did sell a lot of newspapers though… As reported in my previous blog, it’s true that last winter we were in a more precarious position than we are today; still emerging […]
The UK electricity outlook for winter 2023/24

We’re just a short time into the second half of 2023 and it’s time to start thinking about the energy outlook for next winter. In the run up to last winter the media predicted, wrongly, electricity blackouts in the UK. Quite to the contrary I forecast that there would be no blackouts, which was the […]
From London to Atlanta and beyond… PUE can help counterbalance rising energy costs

At the end of this week I’ll be heading across to Atlanta in the United States to attend the excellent ASHRAE Winter Conference and their Technical Committee (TC) 9.9 meetings, as well as the AHR Expo (between 6-8th February). It’s another fantastic opportunity to represent our growing industry, meet colleagues and peers, and share insight. […]
Energy Vampires! Are data centres really to blame for housing delays in West London and Slough?

Back in July 2022 the Greater London Authority (GLA) wrote to the electricity distribution and transmission network operators Scottish & Southern Electricity Networks (SSEN), National Grid Electricity Transmission (NGET) and National Grid Electricity System Operator (NGESO) regarding the issue of insufficient electricity network capacity and delays to connection applications in west London. SSEN is the […]
Pushing the Boundaries of Data Centre Sustainability

Much has been said about the energy crisis unfolding in the UK in the last six months, especially given the unfolding events in Ukraine. To complicate matters further, the climate crisis is accelerating at the same time. As a large scale energy user, both of these serious issues directly impact the data centre industry. The […]
Data centre operators must weather the energy crunch

As we head into the traditional end-of-year season of high energy demand, power prices are continuing to spike, causing concern to consumers and businesses alike. Between August and mid-October 2021, more than 13 UK energy suppliers went out of business. They were casualties of an energy supply crisis that has seen prices rise massively. Wholesale […]
Powering the next generation of Net Zero data centres with HVO

Today the five-nines principle, or 99.999% uptime, is something that practically all data centre providers will promise customers. And to achieve this, many operators across the globe will rely on fossil-fuelled backup generators as a means of mitigating power or grid failures. The overwhelming majority of these gen-sets are powered by traditional, mineral diesel, which […]
PUE – The data centre measure of efficiency that is still going strong…

I’ve spent almost three decades working within the data centre industry and around this time of year it’s usual to see blogs, articles and commentary on “industry predictions” outlining new ways of operating, cooling and monitoring data centre capacity. Despite all this annual change, one measure of efficiency that has always steadfastly remained is the […]
