The winning entry is the Connolly Hospital Blanchardstown Centralised Standby Power Supply Control System Project submitted by Varming Consulting Engineers. 

The HSE Estates Brief entailed complex upgrading of the existing fragmented standby infrastructure into a centralised N+1 resilient network where redundancy is guaranteed even during failure of any primary low voltage or medium voltage component. 

The new centralised standby power supply control system solution required (1) new HVO fuelled 1500kVA generators to be integrated seamlessly with existing control systems of the central MV generators, (2) the replacement of the main LV switchgear in both substations and (3) upgrading of the existing transformers from 1MVA to 1.6MVA.  

Comprehensive pre-planning and meticulous on-site execution in a safe and efficient manner enabled the successful changeover to the centralised standby power supply control system to be achieved with minimal disruption to continuity of electrical supply to the hospital campus.
