High Voltage Connections (HVC)

Power Control Engineers can support organisations with a HVC to the utility with the following services;

  • Undertake a high voltage installation assessment to verify the site’s compliance against statutory requirements and installation condition.
  • Develop a high voltage installation maintenance strategy including specific maintenance tasks to ensure ongoing safe operation of the high voltage installation.
  • Produce a detailed high voltage operating procedure including high voltage safety rules which can be implemented on site.
  • Provide guidance in understanding the role of the high voltage installation responsible person and develop required documentation.
  • Facilitate the execution of the maintenance strategy including engaging subcontractors and specialists to perform maintenance tasks.
  • Provide guidance for planned end of life replacement strategies.

PCE can also provide high voltage infrastructure owners with High Voltage Installation Safety Management Plans (HVISMP’s) which are required by utilities for compliance to the Service and Installation Rules of NSW. Similarly, PCE are able to produce HV submissions required by other utilities in other states and territories under similar legislation.


PCE’s professional ASP3 team are experienced in managing the complete project lifecycle. From the application for a new connection, to design certification with the relevant DNSP, you can rest assured that PCE’s team will support you through the entire design process and provide you with the most cost effective and efficient design solution.
