The Electrical Engineering Group are delighted to start this year with a member presentation by Brendon Clarke, a Principal Electrical Engineer with Aecom, on HV and LV Upgrades - High Criticality and Brownfield Sites. Brendon will present on a recent project undertaken at Palmerston North Hospital that involved the establishment of a new HV supply substation, upgrades to existing HV distribution equipment and an in-situ upgrade of a clinical services LV main switchboard in the basement of the Palmerston North Hospital. The presentation will seek to provide insights into some of the more challenging aspects with upgrading infrastructure in a complex brownfield environment, and notable features implemented to reduce operational risks and ease future replacements. Aspects include: Installation challenges and delivery constraints HV and LV protection coordination with embedded generation present Maintainability and operability design factors Resiliency of supplies and closed source transfer implementation Lifecycle design factors Test approaches and integration verification DDoC's and part 1 deviation requirements Managing installation and commissioning risks Following his presentation Brendon will be available to answer questions at the end.

Join the Electrical Engineering Group for a presentation by Nick Price (Managing Director) and Mike Peters (Senior Commercial Manager) of Tenco. They'll provide an overview of private utility networks. Tenco arranges and manages these networks for commercial property owners – including Kiwi Property, Stride, Precinct and Westfield. Private utility networks are also increasingly common across residential developments, retirement villages and airports. Nick and Mike will discuss the two primary private utility network structures – also referred to as embedded networks and customer networks. - What types of properties are suitable for private utility networks? - Who captures the value from the network? - What are the benefits and drawbacks? - How are solar systems and electrical vehicle charging infrastructure integrated into private utility networks? - What are the typical electrical configurations? Nick and Mike will also walk you through a recent case study and be available following the presentation to answer your questions.
