Data Centre Growth Is Creating New Opportunities for the Electrical Industry
The rapid growth of data centres across the UK is creating significant opportunities for the electrical industry – but new research suggests there could be a challenge finding enough skilled workers to deliver them.
Data centres are the buildings behind much of our increasingly digital world, housing the computer systems required for cloud computing, streaming, online services and, increasingly, artificial intelligence (AI). As demand for these technologies grows, so does the need for new data centre capacity.
Research reported by Electrical Review in September found that the number of data centre developments being proposed in some parts of Britain is growing much faster than the local electrical workforce available to support them.
Data centres need electrical skills
Although data centres are associated with computers and technology, constructing and operating them requires extensive electrical infrastructure.
Large facilities can require complex power distribution systems, switchgear, cabling, backup power, generators, uninterruptible power supplies and sophisticated control systems, alongside cooling and other mechanical services.
That creates work not only during construction and fit-out, but also through commissioning, maintenance and future upgrades.
The Electrical Contractors' Association (ECA) recently described data centres as an important opportunity for UK electrical and engineering services businesses, while warning that expansion must be supported by sufficient grid capacity and a properly skilled workforce.
The scale of the skills challenge is already becoming apparent. Research highlighted by Electrical Review in August found that 100% of UK respondents to Turner & Townsend's latest construction market intelligence survey were experiencing shortages of qualified mechanical, electrical and plumbing workers.
Demand isn't necessarily where the workers are
One particularly interesting aspect of the latest research is where new data centres are being planned.
Analysis by Horizon Platforms looked at 678 full or outline data centre planning applications dating back to 2000. Of 119 applications submitted since the beginning of 2024, 16 were in Wales – around 13% of the recent pipeline. However, Wales accounts for only around 4% of Britain's electrical-installation workforce.
Another significant cluster is developing around west London, Slough and Buckinghamshire. Electrical Review reports that National Grid is already investing in additional infrastructure in the area, including a new substation expected to provide 1.8GW of additional grid capacity and connect more than a dozen data centres.
For the electrical industry, this raises an important question: will there be enough skilled people in the right locations to deliver all of these projects?
What does this mean for people entering the industry?
Data centres won't provide the answer to every electrical employment challenge and there is ongoing debate about how many permanent jobs they ultimately create. However, their construction is another example of how changes in technology are driving demand for electrical infrastructure.
From AI and data centres to renewable energy, EV charging and the continued electrification of buildings and transport, many emerging technologies ultimately depend upon skilled people being able to install, inspect and maintain electrical systems safely.
For anyone currently training for a career in the electrical industry, that's an encouraging message.
Technology may be changing quickly, but behind that technology there remains a very practical requirement: we need people with the skills to build and maintain the infrastructure that makes it work.
