UK First as AI Power Infrastructure Takes a Major Step Forward
ABB and Ark Data Centres are installing the UK’s first medium-voltage uninterruptible power supply (UPS) system to support high-density AI workloads, marking a major step forward in data centre power infrastructure. Designed to handle the intense energy demands of artificial intelligence, the system offers improved efficiency, scalability, and resilience compared to traditional low-voltage UPS solutions, helping ensure reliable, uninterrupted power as AI-driven computing continues to grow across the UK.
Clean Energy Targets at Risk Without Major Workforce Investment, Committee Warns
A parliamentary committee has warned that the Government will only meet its clean energy and decarbonisation targets if there is significant investment in the UK workforce, clearer policy direction for industry, and a stronger role for local authorities. Stephen Melton, Director of Commercial and Compliance at NAPIT, said the UK needs around 250,000 additional workers to meet housing targets alone, with further demand driven by retrofit and renewable projects. The Climate Change Committee estimates up to 725,000 new jobs could be created in the next four years, highlighting major opportunities for electricians and installers, while reinforcing calls from Bill Esterson for long-term policy certainty, clearer guidance on environmental levies, and the swift delivery of the Warm Homes Plan.
