Stage 5 - Construction

The Connection Applicant will undertake detailed design work and will construct/modify their facility.

During construction, and prior to applying for registration, the Connection Applicant must finalise and forward to the connecting Network Service Provider (NSP) and AEMO:

  • Technical data as described in the Generator Connection R1 Submission Checklist.
  • Updated model package, including simulation models and associated design data.
  • Energy conversion model (ECM) data for wind farms and solar farms (semi-scheduled plant) (see Documents checklist below for templates relating to your connection type).
  • Commissioning program – must be agreed with the connecting NSP and AEMO at least three months (for transmission connections) and one month (for distribution connections) before commissioning starts.

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

The Connection Applicant should also consider registration requirements, including:

  • Supervisory Control And Data Acquisition (SCADA) requirements.
  • Obtaining a National Metering Identifier (NMI) from the connecting NSP.
  • Demonstrating the capability of the facility to achieve its performance standards.
