Queen Alexandra Hospital

Faced with the task of having to upgrade an aging backup power system, one of the UK’s busiest NHS hospitals turned to Power Control for a resilient, future-ready solution.

About the Queen Alexandra Hospital
The Queen Alexandra Hospital is a vital healthcare hub for over 675,000 residents across Portsmouth and South East Hampshire. It hosts the country’s largest Ministry of Defence Hospital Unit, Joint Hospitals Group South, and offers a full range of facilities; including Critical Care, Accident and Emergency, Surgical High Care and an array of Cancer Services. With over 900 beds, spread across seven floors, the hospital relies on an extensive array of critical equipment to ensure uninterrupted patient care.

The Challenge
It was considered the older Borri B6033 kVA Uninterruptible Power Supply (UPS) system had reached end-of-life, and would no longer be reliable in providing the essential back-up power protection required for connected medical equipment. 

The hospital needed a modern, highly reliable replacement capable of maintaining electrical continuity in the event of power failure or disruption. Any solution had to meet stringent uptime requirements and provide sufficient runtime for keeping critical systems online - until either a safe system shutdown of any connected equipment could be arranged, or the supply transferred to a replacement generator.

The Solution
Power Control installed two Borri Ingenio Max 200kVA systems, connected in parallel configuration via a new floor-standing external panel. Each system was fitted with three strings of batteries to provide a 60 minute runtime at full load (calculated at 25⁰C and a power factor of 0.8).

A versatile model, the Borri Ingenio Max is a cost-effective and highly-efficient 3-Phase solution for supplying uninterruptible power quality to critical applications. It features a transformer-free design, making it a compact, light and sustainable option. With three level Green Conversion for enhanced system efficiency, the UPS has very low noise and has the lowest Total Cost of Ownership (TCO) in its category.  

Implementation
The entire project, from decommissioning and removal of the old unit to installation and commissioning of the new UPS system, was conducted over a meticulously planned three-week period. A dedicated Power Control engineer remained on-site throughout the process to guarantee the smooth transition between systems and ensure adherence to NHS compliance and safety standards. 

With precise planning, expert engineering and best-in-class technology, Power Control delivered more than just backup power - they provided confidence, continuity and care.  For Queen Alexandra Hospital, the upgraded UPS system now stands as a vital safeguard, powering life-saving equipment when it is needed most.
