Managed IT service provider Redcentric has completed a multi-million-pound electrical infrastructure upgrade as part of a wider data centre refurbishment project at its facility located at Heathrow Corporate Park in London.
The project, which included a UPS replacement, was part-funded through the Industrial Energy Transformation Fund (IETF), now closed for applications, which supports the deployment of technologies that enable businesses with high energy use to transition to a low-carbon future.
As part of Redcentric’s high-profile project, leading UPS manufacturer CENTIEL has delivered equipment to protect an existing 7 megawatts of critical load through its multi-award-winning, highly efficient, true modular uninterruptible power supply (UPS), StratusPowerTM. The deployment of this modular UPS technology enables Redcentric to scale to 10.5 megawatts without the need for any further infrastructure change.
The facility, which is popular with FTSE 100 companies, is now seeing UPS efficiency improvements from below 90% to above 97% since the upgrade. This represents the potential to reduce more than 8,000 tonnes of CO₂ emissions over the next 15 years, supporting ESG compliance for both Redcentric and its household-name clients.
Paul Hone, Data Centre Facilities Director, Redcentric, confirmed, “Our London West colocation data centre is a strategically located facility that offers cost-effective ISO-certified racks, cages, private suites, and complete data halls, as well as significant on-site office space. The data centre is powered by 100% renewable energy, sourced solely from solar, wind and hydro.
“In 2023, we embarked on the start of a full upgrade across the facility, which included the electrical infrastructure and live replacement of legacy UPS before they reached end of life. This part of the project has now been completed with zero downtime or disruption. At Redcentric, we pride ourselves on the high level of uptime across all of our data centres. The continuous reinvestment into new equipment to gain efficiencies now means we can continue to offer our valued clients a 100% uptime guarantee at our London West facility.
“In addition, for 2026, we are also planning a further deployment of 12 megawatts of power protection from two refurbished data halls being configured to support AI workloads of the future.”
Aaron Oddy, Sales Manager, Centiel, added, “A critical component of the project was the strategic removal of 22 megawatts of inefficient, legacy UPS systems. By replacing outdated technology with the latest innovation, we have dramatically improved efficiency, delivering immediate and substantial cost savings.
“StratusPower offers an exceptional 97.6% efficiency, dramatically increasing power utilisation and reducing the data centre’s overall carbon footprint – a key driver for Redcentric.
“The legacy equipment was replaced by Centiel’s StratusPower UPS system, featuring 14 x 500 kW modular UPS systems. This delivered a significant reduction in physical size, while delivering greater resilience, as a direct result of StratusPower’s award-winning, unique architecture.
“StratusPower provides an unprecedented level of resilience and availability, guaranteeing near-zero system downtime, ensuring the data centre can offer its clients the highest standard of power protection. Standardising with this design across the site enables UPS modules to be seamlessly redeployed between systems, ensuring maximum asset utilisation and operational agility.”
Durata, a leader in modular data centre solutions and critical power infrastructure, completed the installation to the highest standards.
Hone continued, “Environmental considerations were a key driver for us. StratusPower is a truly modular solution, ensuring efficient running and maintenance of systems. Reducing the requirement for major midlife service component replacements further adds to its green credentials.
“With no commissioning issues, zero reliability challenges or problems with the product, we are already talking to the Centiel team about how they can potentially support us with power protection at our other sites.”
