The construction stage

The connection applicant will undertake detailed design work and construct or modify their facility. Any augmentation to the Declared Shared Network (DSN) will be designed and constructed by:

  • the selected Declared Transmission System Operator (DTSO) – for the contestable portion of the augmentation
  • the incumbent DTSO – for the non-contestable portion of the augmentation.

VicGrid Connections reviews construction progress reports, facilitates the resolution of any technical issues, and escalates them if required.

During construction, you should update, finalise and forward to us:

  • updated model package, including simulation models and associated design data
  • energy conversion model (ECM) data for wind farms and solar farms (semi-scheduled plant)
  • commissioning programs – must be agreed with us at least 3 months prior to the commencement of commissioning.

If there are material changes to the simulation model or other aspects of system design, we need to review and reassess the agreed performance standards.
