Socomec launches energy audit initiative for UKI data centres

Socomec, a manufacturer of low voltage power management systems, has launched an energy audit programme for data centres in the UK and Ireland, aimed at helping operators measure energy use and meet reporting requirements under the EU Energy Efficiency Directive (EED). Under EU EED rules, owners and operators of facilities with a capacity above 500kW must disclose their power usage effectiveness (PUE) and other environmental performance indicators each year. The next reporting deadline is 15 May 2026. The directive closely aligns with the UK’s Energy Savings Opportunity Scheme (ESOS) and the ISO 50001 standard, which requires organisations to monitor and report energy consumption and power utilisation accurately. Improving PUE is also becoming an operational priority for data centres as electricity costs increase and workloads linked to artificial intelligence raise power demand. Socomec estimates that improving PUE by 0.1 - from 1.6 to 1.5, for example - can reduce annual energy consumption by around 6–8%. For a 2MW data centre, this could equate to more than £100,000 in yearly energy savings while also extending the lifespan of existing infrastructure. Energy infrastructure assessments for operators Data centre operators in the UK and Ireland can apply for an assessment of their energy infrastructure through the programme. Socomec’s engineers will carry out site inspections covering IT and non-IT loads, including UPS systems, server racks, cooling equipment, lighting, and switchgear. The aim is to determine PUE and identify gaps in existing metering capabilities. Participating facilities receive a report outlining energy efficiency measures, estimated cost savings, and potential return on investment. The findings are intended to support decision-making across sustainability, finance, and engineering teams. The audits are particularly relevant for older colocation data centres seeking to measure PUE at rack level using Measuring Instrument Directive-compliant metering. More detailed measurement can also allow operators to allocate energy costs more accurately between tenants. Colin Dean, Managing Director of Socomec, says, “The EU EED represents a gold standard for sustainable energy management and it’s only a matter of time before other countries follow Germany’s example and start penalising non-compliance. "In addition, there is a fear - particularly among legacy data centre operators - that a rip-and-replace approach is needed to achieve modern energy efficiency. At Socomec, our aim is to plug this gap with proactive and practical guidance, showing that metering can be retrofitted to improve efficiency without infrastructure overhaul or operational downtime. “Our energy audit is designed to help operators of mission-critical data centres take informed action towards sustainability while maximising their investments. With clear, accurate insights into PUE, data centres can turn energy data into action, optimise operational costs, and drive long-term resilience.”

Reshaping data infrastructure to help carriers digitally transform

At MWC Barcelona 2026, Yuan Yuan, President of Huawei Data Storage Product Line, shared Chinese multinational technology company Huawei's key insights and innovations for enabling carriers to plan their data infrastructure, address challenges in AI adoption, and prepare for IT architecture transformation in the AI era. Data preparation for AI: From dormancy to awakening In the age of AI, data is an essential asset. Yuan noted that in the past two years, over 90% of enterprises actively embraced AI for business innovation, but fewer than 10% have successfully mastered and scaled AI technology. There are three primary challenges: persistent data silos that hinder data collaboration across regions and organisations; a lack of quality data supply, especially industry-specific knowledge; and inefficiencies in the data preparation phases like data collection, cleansing, and labelling. This results in AI applications falling short of commercial viability, raising doubts about the return on investment. Yuan predicts, "In the future, cold data will become a thing of the past. Data will shift from 'offline' to 'always online,' and retention policies will move from being compliance-driven to a principle of retaining and never deleting. Consequently, data volumes will expand from petabytes to exabytes, which will drive demand for greener, more efficient data infrastructure." Architectural transformation: From storing data to storing knowledge and memory As AI agents become the primary consumers of data, data infrastructure must evolve to embrace new data paradigms, including vector, graph, and key-value (KV) semantics. To eliminate AI hallucinations and enable continual AI evolution, data infrastructure must be capable of storing knowledge and memory. Yuan discussed Huawei's AI data platform, an innovative solution that integrates knowledge, memory, and inference acceleration services into a single storage system. This consolidated approach significantly reduces system complexity and O&M costs. The platform delivers a massive upgrade in performance. Inference efficiency (measured in tokens generated per second) is multiplied, while latency (time to first token) is reduced by 90%. Furthermore, the continual evolution of data, knowledge, and memory makes AI agents smarter over time. As Yuan explains, "In the future, every carrier will need its own AI data platform to help agents understand business processes, acquire domain-specific expertise, and iterate and upgrade rapidly. Otherwise, AI will remain nothing more than an expensive toy." AI adoption planning: From AI exploration to AI-driven service upgrades Although many carriers have made AI a strategic priority and are beginning to adopt it, significant challenges remain in real-world deployment: inference failure, inference costs, and inference speed. Yuan presented an intelligent computing service platform, jointly developed with a Chinese carrier, that tackles these challenges. The platform uses the KV cache technology to improve storage resource utilisation and supports inference applications of different large models like DeepSeek and Qwen. It optimises cost-effectiveness by innovatively eliminating repeated computing via querying. Through the collaboration of on-chip memory, DRAM, and AI storage, the platform enables PB-scale KV cache storage. This improves the overall throughput by more than 10 times, reduces inference costs by about 50%, and shortens response time to less than one second. In addition, algorithm optimisation addresses challenges like low KV cache hit ratios and inference failure due to long-sequence inputs in research report analysis. Serving as the foundation for AI, the platform has been deployed at scale at the group to enable multidimensional innovation across services, including internal IT systems, B2C services, B2B services, and B2H services. Yuan says, "Planning AI training and inference platforms requires more than focusing on computing power and models; deep collaboration between storage and compute is also essential to improve system-level efficiency and user experience." Yuan highlighted that AI is reshaping data infrastructure. In the AI era, storage systems will evolve into intelligent engines, which will not only store critical data assets, but also serve as the knowledge sources and memory carriers for the continuous evolution of AI agents. He called on carriers to prioritise accumulation and protection of quality data, and to plan and build a unified AI data platform that supports a wide range of large model applications while enabling service innovation for both internal operations and external offerings. Huawei says it will continue to advance technological innovation and architectural upgrades to help carriers digitally transform. For more from Huawei, click here.

Power supply options for data centres

In this exclusive article for DCNN, Tania Arora and James Wyatt, Partners at Baker McKenzie (London), examine the evolving landscape of data centre power supply, highlighting why a tailored approach - blending grid connections, on-site generation, microgrids, and emerging technologies such as SMRs and battery energy storage - is increasingly essential for resilience, sustainability, and commercial optimisation: No universal solution Data centres presently require considerable energy resources, with projections indicating a marked increase in their consumption in the coming years. Securing a steady, sufficient, reliable, and scalable power supply is crucial for the financing, operational success, and long-term resilience of any data centre. A universal strategy does not exist for procuring power for data centres; each project requires a tailored approach. The market offers a wide range of power supply options and these are frequently combined to address the specific requirements of each project. The exact power procurement strategy for each project is determined by several factors, most notably the location of the data centre, local regulatory frameworks, its current and future operational needs, and the strategy of the developer (particularly considering other assets / other electricity supply arrangements they own). This article considers power procurement options available in the market and how these could be combined to achieve a successful power supply strategy. The key power supply options available at present include grid power, on-site or adjacent-site power generation, and microgrids (renewable or conventional), supported by backup generators, battery energy storage systems (BESS), and fuel cells. On-site or adjacent-site nuclear power is increasingly viewed as a panacea solution for data centre energy needs, although there are still considerable political, technological, and risk-allocation problems to solve. Data centres usually connect to public electricity grids, but most grids were not designed for their high load. Upgrades and expansions are often needed, which can be time-consuming and expensive. Sometimes, users must pay for these improvements, and further upgrades may be required if the data centre expands. Furthermore, securing a grid connection is rarely guaranteed; capacity reservations may be needed and are often subject to legal conditions. In some cases, installing on-site generation and microgrids can help address grid challenges. This could involve constructing solar and wind power plants (supported by BESS), gas-fired power stations, and/or combined heat and power (CHP) units adjacent to the data centre and supplying electricity directly without relying on the public grid. Furthermore, fuel cell and linear generator systems - as well as small modular reactors (SMRs) - are emerging as low-carbon, scalable power solutions for data centres. While the ongoing costs for self-generated energy are generally much lower, building such a dedicated energy infrastructure typically entails significantly higher upfront costs compared to connecting to the public grid. Furthermore, on-site projects are often constrained by space and planning restrictions, particularly in urban or suburban markets where demand is highest. Sustainable options Sustainability is a key consideration for a number of data centre market participants. Even if on-site wind or solar energy is economically viable for a project, these renewables alone cannot provide a stable base load due to their intermittency. To ensure base-load coverage, additional infrastructure such as energy storage systems, fuel cells, and conventional backup generators are required. SMRs and advanced nuclear technologies are emerging as promising solutions for the rising power needs of data centres. They offer reliable, consistent base-load power, load-following capability, scalable output, low carbon emissions, and a small physical footprint. They can operate independently of the grid or alongside renewables and are designed to be more cost-effective and quicker to deploy than traditional large-scale nuclear plants due to modular construction and established supply chains. SMRs are becoming a tangible reality for data centres. For example, the UK Government recently provided a considerable amount of support for SMRs for data centres through planning reforms, regulatory acceleration, funding, and explicit policy direction encouraging SMR–data‑centre colocation. However, SMRs face challenges: they are largely unproven and most jurisdictions still lack regulatory frameworks tailored to their unique characteristics. Key considerations for deploying SMRs include understanding local nuclear regulations, licensing and approval processes, decommissioning requirements, nuclear waste management, fuel supply security, and site suitability. Addressing these legal and regulatory issues is essential before SMRs can be widely adopted for data centres. BESS has become a key part of data centre power strategies, serving not only as resilience infrastructure but also helping to unlock commercial opportunities. It provides load shifting and peak shaving, thus reducing exposure to volatile wholesale prices and network charges by charging during low-cost or high-renewable periods and discharging power at peak demand. BESS also delivers instant backup power during outages and enables participation in grid services for additional revenue. Key issues include permitting and safety (especially for large-scale systems near nuclear or high-voltage facilities), complex grid connection agreements, and risk allocation where BESS is delivered via third-party energy-as-a-service contracts. Final considerations The near to mid-term future of data centre power lies in combined strategies. Every option in the combination presents its own distinct legal and commercial considerations. Consequently, as strategies become more complex, market participants should anticipate navigating a greater number of legal issues within the context of rapidly evolving regulatory frameworks.
