Delivering reliable back-up power supplies during regular scheduled maintenance windows
As one of the UK’s first NHS Foundation Trusts, this hospital in Sutton, Surrey relies on robust hospital backup power to ensure uninterrupted healthcare services for the local community and beyond. To deliver round-the-clock care, the hospital upholds strict standards for maintaining essential equipment, including its on-site electricity substation and transformers.
With a rolling upgrade schedule in place, the hospital required a reliable provider of backup and mains power, as well as a team capable of delivering consistent support during brief maintenance windows. Most critically, while the on-site transformers were offline, the hospital needed a trusted partner to ensure uninterrupted power supply for essential day-to-day patient care.
Project Summary
Before the scheduled shutdown, MEMS collaborated closely with the hospital to guarantee reliable backup and mains power throughout the maintenance window.
Drawing from its extensive fleet, MEMS selected generators specifically matched to the size of the transformers being upgraded, ensuring cost efficiency. A dedicated MEMS project manager was assigned to oversee the process, supported by a team of experienced electrical technicians who handled the setup and operation of each generator.
MEMS provided a comprehensive solution, including all necessary power generation equipment and cabling. The generators were refuelled as needed and monitored remotely to ensure seamless performance with no onsite issues.
Following the completion of the transformer upgrade, MEMS returned ahead of other contractors to efficiently remove all cables, disconnect the generators, and clear supporting equipment. This proactive approach prevented any delays on the final day of work.
The Results
From the very start, a strong working relationship meant the hospital could depend on MEMS for both major and minor maintenance schedules.
With MEMS as a trusted partner, the hospital was confident it would receive timely, reliable power solutions with zero risk of failure. The outcome spoke for itself: from A&E to operating theatres, every system and piece of essential equipment stayed fully operational throughout the maintenance. Work went unnoticed, disruptions were avoided, and patient care continued seamlessly, giving the hospital team complete peace of mind.
