Data centre cuts emissions with shift to hourly renewable power


A large UK data centre has reduced its carbon emissions by 75% after changing how it sources electricity, aligning its power use with renewable generation on an hour- by-hour basis. Stellium Datacenters, which runs a major


high-performance computing campus near Newcastle, said the change allows it to match its electricity demand directly with output from renewable sources rather than relying on annual accounting methods. The company worked with Good Energy to implement the system, drawing on power from more than 3,300 independent UK generators. The approach comes as scrutiny of data


centres intensifies amid concerns that the rapid expansion of artificial intelligence and cloud computing could put strain on electricity networks. The issue is under investigation by MPs through the Environmental Audit Committee, which is examining energy use, water consumption and pressure on local infrastructure. Stellium said its site now achieves


an hourly renewable matching score of 95.4%, compared with an estimated market average of about 43%. Planned battery storage is expected to raise this figure further. The system also enables the company to identify which renewable assets are supplying its electricity at specific times. Many data centres currently rely on


certificates showing that renewable electricity has been generated somewhere on the grid over a year, even if fossil fuels are used during periods of peak demand. Stellium said its method provides a more precise account of real-time energy use. Nigel Pocklington, chief executive of Good Energy, comments: “By matching electricity use with renewable generation hour-by-hour, Stellium can show when clean power is actually being used – not just claimed on paper. That kind of transparency cuts carbon emissions, reduces reliance on fossil fuels at peak times and proves that digital growth and a resilient energy system can go hand-in-hand.”


Port of Dover reaches net zero


target ahead of schedule The Port of Dover has reached net zero emissions for its direct operations, significantly earlier than both industry and government timelines. Its Scope 1 and 2 emissions for 2025 have been reduced by 98.3% compared with


2007 levels. The achievement follows external verification of emissions data against international standards, including ISO 14064 and the Greenhouse Gas Protocol. The milestone was achieved through a combination of operational changes, including the use of hydrotreated vegetable oil to power machinery, installation of 1.5MW of on-site solar generation, and wider energy efficiency measures such as switching to renewable electricity and upgrading lighting and heating systems. Remaining emissions have been offset through a locally based regenerative farming scheme certified under the UK Carbon Code of Conduct. The port reached the target at


least five years ahead of other UK port ambitions and 25 years before


the UK government’s maritime net zero goal. Activity in the Dover Strait accounts for around 8% of the UK’s maritime emissions, making the reduction notable for the wider sector. Chief executive Doug Bannister comments: “We are proud to be celebrating this


milestone moment, which has seen our carbon emissions reduce drastically from nearly 14,000 tonnes 18 years ago. Since setting our goal four years ago, people from across the Port have all contributed to this incredible result.” Attention is now expected to shift towards reducing indirect emissions across the wider maritime supply chain, which requires coordination between ports, operators and government.
