The updated Underground Distribution Scheme (UDS) Manual is now available, with changes to come into effect as of 1 July 2024.

The UDS manual, now in its 12th edition, outlines new requirements for network administration, design and installation in land development and subdivision projects.

  The updated edition includes key changes such as:

  • new content for existing overhead network assets within road reserves and properties
  • updated developer responsibilities and clarifications
  • additional focus on network safety in design requirements
  • updated requirement to network reliability to advance fault location and network restoration
  • revisions to flood and water table content, and point of supply connections
  • changes to the requirements for cables near retaining walls and to service pillar locations
  • a new option to permit a developer to undertake a simple connection service subdivision where the project incorporates civil works.
  • removal of SUDL (Serviced Uncleared De-Energised Lots) option and clearance conditions further clarified
  • new UDS Structure diagram highlighting the different parties involved and their relation to each another.

The updated UDS manual is the result of significant consultation, obtained through more than 600 feedback submissions, internal workshops and industry forums.

Western Power acknowledges the valuable input from the Urban Development Institute of Australia, the Property Council of Australia, participants from the Subdivision Design Forum and other industry stakeholders.

To meet the evolving needs of WA’s main electricity network, consumers and industry, the UDS manual will continue to be updated with the latest advice and to reflect the outcomes of Western Power reviews and initiatives.

A two-month transition period until the end of June will enable customers to align with the new requirements.
