With the NHS driving toward Net Zero, AE Eugene Conroy highlights common power-related issues across ageing estates and explains why resilient, future-ready electrical infrastructure is essential.
With an ageing estate, and the NHS driving toward Net Zero, hospital electrical systems face mounting stress and increasing rates of failure. Drawing on his over 25 years of hands-on experience, Authorising Engineer Eugene Conroy C. Eng, FIHEEM, MIET, MSc, highlights common power-related issues across NHS estates – from design flaws to operational shortfalls. As the NHS advances digitalisation and electrification, resilient and future-ready electrical infrastructure is essential.
This paper serves as a practical aide-memoire for estates managers and designers.
Many NHS Trusts are unaware of their District Network Operators (DNO) capacity constraints until late in project development, only to discover they are operating above their agreed capacity, incurring untimely and costly enhancement works. Issues include increased capacity for electrification (heat pumps, EV charging), DNOs requiring costly offsite reinforcement, and non-compliance with ENA G81 design standards and ESQCR.
