US data centre pipeline growth slows in Q1

The pace of new US data centre developments slowed during the first quarter of 2026, with developers increasingly focusing on advancing existing projects rather than announcing new capacity, according to global research and consultancy firm Wood Mackenzie. Its latest US data center pipeline: Q2 2026 report found that 36GW of new data centre capacity was added to the development pipeline during Q1 2026, a 19% decline compared with Q4 2025. Total disclosed pipeline capacity now stands at 331GW, with around 40% of projects under active development. Wood Mackenzie says the slowdown reflects a more challenging development and regulatory environment, with established developers prioritising the delivery of existing projects. Caitlin Connelly, Senior Analyst at Wood Mackenzie, explains, "Established data centre developers continue to shift their focus to the maturation of their existing pipelines in the face of an increasingly challenging development and regulatory environment. "New entrants focused on gas supply and land access are targeting states such as Texas and Utah, but only a small fraction of those projects are under active development." Investment remains strong despite slower additions Texas continues to lead the US market with almost 100GW of planned capacity, followed by Ohio. New projects are also being planned in states including Utah, New Mexico, and West Virginia, although relatively few have progressed into active development. The report found that 53% of projects have passed the permitting stage, although these account for only 32% of total planned capacity. Meanwhile, signed construction or electricity supply agreements now cover 195GW of capacity, equivalent to around 26% of the United States' peak electricity demand in 2025. Wood Mackenzie also reports that disclosed capital investment in specific projects has exceeded $1 trillion (£743 billion). However, investment remains highly concentrated, with just 6% of projects accounting for 42% of total disclosed capital expenditure. The report also highlights increasing use of behind-the-meter power generation, particularly in Texas. Across projects where generation strategies have been disclosed, gas accounts for 48% of total site capacity, while renewable energy and battery storage represent 38%. Caitlin continues, "The regulatory environment for data centre development is increasingly complex and regionally diverse. Interruptible service options are being deployed, forcing companies to choose between speed to power and firm power. Policymakers tend to view firm service as an unnecessary friction to interconnection. "Fast-track capacity interconnection frameworks seek to bring new generation online quickly ahead of a supply crunch. It remains to be seen whether policy developments help or hinder demand growth, however, as policymakers seek to balance the often competing priorities of affordability and speed to power."

Data Centres APPG launches UK growth inquiry

The Data Centres All-Party Parliamentary Group (APPG) has launched a parliamentary inquiry to examine whether the UK's policy and regulatory framework is supporting the future growth and international competitiveness of the data centre sector. Titled Unlocking the UK's Data Centre Growth Opportunity, the inquiry will gather evidence from across the industry before publishing policy recommendations in December 2026. Written submissions are being invited from data centre operators and developers, investors, technology companies, utilities, combined authorities, regulators, academic institutions, and organisations representing environmental and community interests. Evidence must be submitted by 17:00 on 25 September 2026. Inquiry to examine key growth challenges The inquiry will include three oral evidence sessions between September and November, focusing on energy infrastructure and international competitiveness, investment and planning, and innovation and sustainability. It will also consider skills, workforce development, and the UK's long-term policy direction. Chris Curtis MP, Chair of the Data Centres APPG, comments, "Data centres are fast becoming some of the most significant infrastructure investments in the country and, with the right approach, they can deliver good growth, good jobs, good skills, and lasting economic and social benefit in the communities that host them. "This inquiry is about making sure that as the sector expands, it does so in a way that spreads opportunity across every region of the UK, not just where investment already concentrates. I'd encourage anyone with a stake in this agenda to submit evidence and help us build the case for growth that works for everyone." Alison Griffiths MP, Vice Chair of the Data Centres APPG, adds, "Data centres sit at the intersection of our national security, economic future, and environmental responsibilities. As demand for cloud computing and AI grows, communities are rightly concerned about the land, energy, and water they use. "As Vice Chair of the Data Centres APPG [...] and as a member of the Environmental Audit Committee, I want this inquiry to challenge operators to go beyond business as usual, improve their environmental performance, and demonstrate lasting value to the communities hosting them." David Reed MP, Officer of the Data Centres APPG, says, "The UK has a real opportunity to lead the world in data centre investment, but we should be under no illusion: other markets are competing hard for the same capital, the same skills, and the same technology. "This inquiry will look squarely at how the UK stacks up internationally, what's holding us back, and what reforms are needed to keep Britain at the front of the pack. I want this group to make the practical, evidence-led case for the policy changes that will secure our competitive standing for the next decade." The Rt Hon. Lord Philip Hunt of Kings Heath OBE, Officer of the Data Centres APPG, notes, "We cannot talk about data centre growth without talking honestly about energy, water, and sustainability. The sector's expansion will place real demands on our grid and our natural resources. This inquiry is an opportunity to hear from those developing the solutions, and to ensure sustainability isn't an afterthought but a condition of good growth."

Secure I.T. completes UPS and AHU upgrades for NHS

Secure I.T. Environments (SITE), a UK design and build company for modular, containerised, and micro data centres, has completed uninterruptible power supply (UPS) and air handling unit (AHU) upgrades at two live data centres operated by an unnamed NHS Foundation Trust. The projects were carried out while both facilities remained operational and were designed to improve resilience, energy efficiency, and future scalability for the Trust's critical digital infrastructure. The UPS upgrade replaced two end-of-life systems with modular Riello Multi Power infrastructure. SITE installed two 252kVA UPS chassis, each configured at 84kVA N+1 using 42kW power modules. The modular design allows additional capacity to be added in the future without replacing the entire platform. Cooling upgrade improves efficiency The second project involved replacing ageing AHUs at a data centre originally designed and built by SITE during the 2000s. The facility supports a hospital with more than 800 beds, outpatient services, and one of the South East's busiest emergency departments. As part of the works, the existing condenser compound was decommissioned and replaced with a new ground-level installation designed to improve heat rejection performance. The upgraded FläktGroup AHUs were specified to maintain environmental conditions during higher ambient temperatures, whilst also incorporating physical security measures and remote monitoring capabilities. According to SITE, the new cooling equipment is expected to reduce carbon emissions by more than 58,000kg annually and deliver energy cost savings of approximately £32,305 per year, with a projected return on investment of just over three years. Working around ongoing operations The projects were delivered in carefully planned phases to minimise disruption to hospital operations. The UPS systems were replaced one at a time over two weekend shutdowns, with construction work for the cooling upgrade being scheduled to reduce the impact on visitors and nearby clinical services. A spokesperson for the Trust comments, "This was a big and critically important project for the hospital, carried out smoothly by Secure I.T. Environments. We were really grateful for the work and professionalism of the team, and its partners Riello, throughout the project." The UPS project also included new underfloor containment and cabling, DC transition boxes, integration with the existing battery strings following testing, remote monitoring, commissioning, load bank testing, and operational training for estates engineers. Jo-Anne Garvie, Commercial Director at Secure I.T. Environments, says, "In hospital environments, the resilience of supporting infrastructure has to be treated with the same discipline as the IT systems it protects. "These projects have resulted in a more flexible and maintainable power platform and energy-efficient cooling infrastructure. Together, they support the Trust's current operational needs and give it a clear path for future expansion." For more from SITE, click here.

Quantum chip concept aims to improve scalability

Researchers at The University of Warwick and Canada's National Research Council (NRC) have proposed a new chip architecture that could address one of the main barriers to scaling quantum computers by enabling communication between qubits over much greater distances. Published in APL Quantum, the research introduces the concept of Quantum Phononic Links (QPLs), which use sound-like vibrations, known as phonons, to transfer quantum information between qubits located across a semiconductor chip. The researchers say the approach could help overcome a limitation of current quantum chips, where qubits typically communicate only with neighbouring qubits, as future large-scale quantum computers are expected to require communication between millions of qubits distributed across an entire chip. Maksym Myronov, Department of Physics at The University of Warwick, says, "One of the key challenges in quantum computing is long-range qubit connectivity. Our work introduces a new concept in which phonons act as a quantum bus, enabling distant qubits to exchange quantum information while remaining fully compatible with semiconductor technology." New material supports long-range qubit communication The proposed architecture is based on compressively strained germanium on silicon (cs-GoS), a material developed at The University of Warwick using epitaxial growth techniques. According to the researchers, qubits within the material are highly sensitive to vibrations travelling through the germanium layer. By controlling these vibrations, quantum information could, in principle, be transferred between qubits positioned either adjacent to one another or separated across semiconductor chips measuring up to 300mm in diameter. The team says this differs from other approaches that rely on microwaves or externally generated surface acoustic waves, which typically require additional hardware and more complex chip designs. Instead, QPLs are integrated directly into the semiconductor material hosting the qubits. The researchers suggest that compatibility with existing semiconductor manufacturing processes could support the development of more scalable quantum processors in the future.
