ELECTRICAL INFRASTRUCTURE


automatically disconnected when standby generators are in use, which also avoids fault level issues.


Tertiary supplies Additionally, tertiary supplies, which are provided by uninterruptible power supplies (UPS), are only required for the highest risk grade departments. Selecting locations for UPS in already busy areas can be challenging to ensure that conditions for good battery life are maintained. Large ventilation plant rooms, often above operating theatre departments, are locations where it may be possible to achieve acceptable temperature conditions by ventilation alone. Finally, cybersecurity risks are a growing concern as more components – such as CT scanners or CHP units, connect to the internet for remote diagnostics. Increasingly, internet-connected devices may be embedded in equipment without it being obvious to the casual observer. So, it is important to obtain assurance from the manufacturers about the security of these connections and their compliance with NHS protocols for accessing IT networks. This approach will need to be developed to assess and manage the introduction of Artificial Intelligence into functional safety and safety-critical systems. This is an evolving area to watch.


3: What can be done to ensure your estate has the capacity to accommodate embedded renewable generation such as solar PV?


There are very few hospital sites with sufficient spare land to install a solar farm or a wind turbine. Other forms of renewable generation have been experimented with, but haven’t matured into reliable technology. In most sites, space is at a premium, making building-


mounted PV panels the most practical systems to install. On a hospital site operating 24/7, the electricity generated during daylight from PV is usually used on site, and it is unlikely that any excess will arise, so there is no advantage in exporting excess or having battery storage to store it for later use. Where the healthcare site focuses on outpatients, and only operates on weekdays, it may be desirable to consider battery storage to save energy generated at the weekend for use the following week. Except for the smallest installations, it will be necessary


to make a G99 application for each PV installation. The need for early engagement with the DNO cannot be overstated – such is the pressure on the National Grid that it cannot be assumed that a connection can be accommodated straight away.


4: Decarbonising your estate, and preparing to meet the requirements of Net Zero Carbon


Thermal energy for hospitals is traditionally produced in a central boiler house or energy centre using fossil
