Core grid determination

About this Consultation

The core grid determination consultation paper outlines the Commission's proposed approach to the determination of the Core Grid, together with its draft Core Grid Determination, as required by rule 5A of section III of part F of the Electricity Governance Rules 2003 (Rules). Determining the core grid is an important step in the process of completing the Grid Reliability Standards (GRS) framework. Once the core grid is determined, the capability of the grid to meet the GRS can be fully assessed. A draft Core Grid schedule has been prepared consistent with the proposed approach to the Core Grid Determination. This draft is attached as Appendix 1 of the consultation paper.

It has been brought to the Commission's attention that the diagram on p.45 of the paper does not reflect the information shown in tables 6 and 7 of the consultation paper. This inadvertent error has been corrected and an updated p45, showing the correct diagram is below.

The Core Grid, once approved by the Minister, becomes a schedule to the Rules, it constitutes a rule change and is therefore subject to the rule change requirements set out in the Electricity Act 1992 (Act). To assist stakeholders, and in recognition of the requirements on the Commission under the Act, the paper sets out, the Commission's rationale for proposing the draft Core Grid Determination, other options considered, and the Commission's assessment of its proposal against the Core Grid objectives under Part F, and the overall objectives under the Act.

Submission requirementsThe Commission invites submissions on the proposal and in answer to the specific questions in the consultation paper by 5pm on 20 July 2005. Please note that, because of the statutory timing obligations of the Commission, submissions received after this date may not be able to be considered. For the same reason, there will be no opportunity for cross-submissions.
