New energy agreement for nLighten’s UK data centres

nLighten, a provider of sustainable edge data centre services operating across the UK, Germany, France, and the Netherlands, has entered into a new renewable energy supply agreement with UK-based provider Conrad Energy, covering all of nLighten’s edge data centre locations across the UK. Unlike traditional supply contracts, the agreement enables nLighten to monitor its renewable energy consumption with granularity – down to the asset level and on an hourly basis. The partnership, which initially started in April 2024 with the delivery of renewable power, was enhanced in January 2025 with the introduction of detailed tracking and reporting capabilities. Previously, nLighten’s UK energy procurement was based on market-driven purchases supplemented by annual Guarantees of Origin. Conrad Energy has progressively onboarded all nLighten UK meters, consolidating what was previously a fragmented energy procurement approach. Each month, nLighten receives a breakdown of its renewable energy supply from Conrad Energy. This includes asset-level insights into the share of wind, solar, and biomass sources contributing to the energy mix. The data allows nLighten to track its renewable coverage over time and calculate avoided CO₂ emissions based on the actual generation profile. “This collaboration goes beyond what most energy suppliers currently offer in the UK,” claims Francesco Marasco, VP of Energy Operations & Sustainability at nLighten. “Not only can we align our procurement with real-time pricing, but we now also have full transparency over how – and where – our renewable energy is being generated. It’s another step towards building the most sustainable edge data centre platform in Europe.” This model builds on learnings from a similar agreement nLighten established in Spain with Shell. However, the Conrad Energy agreement takes transparency a step further by providing visibility down to individual generation assets, not just the source. “We’re proud to support nLighten’s efforts to lead the way in data centre sustainability,” says Tim Foster, Director of Energy for Business at Conrad Energy. “By combining flexible supply structures with granular data visibility, we’re helping digital infrastructure operators align more closely with today’s energy realities and decarbonisation goals.” For more from nLighten, click here.

ZTE urges industry to rethink energy efficiency

ZTE Corporation, a Chinese multinational telecommunications equipment and systems company, showcased its AI-embedded solution for data centre infrastructure at Data Centre World Frankfurt 2025. As artificial intelligence becomes deeply integrated into every layer of enterprise and cloud computing, the foundation of digital infrastructure is undergoing a fundamental transformation. Speaking at the event, Hans Neff, Senior Director of the CTO Group at ZTE, delivered a keynote address that challenged traditional efficiency metrics and static data centre models. He emphasised that in an AI-driven future, conventional benchmarks such as Power Usage Effectiveness (PUE) are "no longer sufficient" to measure the performance and adaptability of modern data centres. In his address, Hans highlighted the paradox facing today's data centres: at the very moment when sustainability has become a strategic priority, AI is driving up compute intensity and energy demand at an unprecedented scale. He believes traditional benchmarks, originally designed for static, legacy systems, are no longer capable of capturing the complexity and dynamism of AI-driven workloads. "AI workloads are fundamentally different," says Hans. "They're denser, hotter, and more variable. To stay ahead, we can’t keep optimising for a world that no longer exists." ZTE says its approach, drawn from global deployments and internal R&D, envisions energy efficiency not as a fixed target, but as an evolving system. The company states that it is engineering data centres that sense, predict, and respond to changing computational demands in real time. In his keynote address, Hans also called on the industry to adopt more holistic metrics that better reflect the realities of modern data environments. He proposed a new composite framework that evaluates energy use not only by its efficiency, but also by its effectiveness in supporting intelligent operations, resiliency, and sustainability. "PUE is no longer enough," argues Hans. "We need smarter metrics that account for how power is used — not just how much." For more from ZTE, click here.
