The Network Technical Code and Planning Criteria (NTC) mandates that Power and Water in its role as the Network Operator develop ‘System Strength Impact Assessment Guidelines (SSIAG)’ and ‘Generator and Load Model Guidelines and Model Change Management Requirements (Model Guidelines)’ for Power and Water’s Regulated Networks. The SSIAG provides guidelines for undertaking a system strength impact assessment for proposed new or altered generating systems or network service facilities, and the draft Model Guidelines provide guidance for Users regarding the requirements they are expected to meet in providing computer models and associated information for their connected plant and equipment.

Draft versions of these guidelines have been developed and are published below for consultation to enable feedback from Users and the Utilities Commission consistent with clauses 3.3.5.15 and 3.3.4(f) of the NTC.

Interested parties can provide feedback to Power and Water by emailing NetworkDevelopandPlanning.PWC@powerwater.com.au by 4pm Friday 28th August 2020. It should be noted that Power and Water will publish submissions in full. Should a stakeholder consider sections of their submission as confidential, a separate public version of the submission should also be provided to Power and Water for publication. Given the related subjects covered by the two guidelines they have been released together to enable a more efficient consultation.

In addition to the documents attached, Power and Water will be holding a stakeholder information session in the week commencing Monday 10th August 2020, details on the venue and time to be confirmed. Video conferencing facilities will be available and encouraged to ensure social distancing requirements can be observed with room restrictions. Up to 2 people per organisation are able to register. If you are interested in attending please register by 4pm Friday 7th August 2020 by emailing NetworkDevelopandPlanning.PWC@powerwater.com.au
