Centiel has won the Modernisation & Retrofit Project of the Year category at the Data Centre Review DCR Excellence Awards 2026, for the electrical infrastructure upgrade completed at Redcentric’s Heathrow Corporate Park colocation facility.
For a Facilities Manager weighing a UPS retrofit, the award is a headline. The detail underneath it is the part worth reading.
The project replaced legacy UPS protecting an existing 7 MW critical load with Centiel’s StratusPower modular UPS, with the system design allowing the facility to increase capacity to 10.5 MW without additional infrastructure work. Operating efficiency rose from below 90% to more than 97% — a change that compounds over the equipment’s operating life.
None of that is unusual for a retrofit pitch deck. What’s harder to find is a live, multi-tenant facility confirming it happened with zero downtime or disruption, and that there were no commissioning issues, no reliability challenges, and no problems with the product once it was in service.
That’s the proof point that matters more than the trophy: a modular architecture that lets individual UPS modules be isolated, tested, and swapped inside a live frame — without transferring the load to bypass, and without opening an SLA exposure window to explain to tenants afterward.
StratusPower is built on Centiel’s DARA — Distributed Active Redundant Architecture. Each module is a self-contained UPS with its own control logic; no single control board, static bypass, or communication path can take the whole system down. It’s the same architecture behind the capacity headroom in this project: growth without a redesign cycle.
