<h3>
Background</h3>
<p>
On 13 November 2008, NEMMCO lodged a Rule change proposal to remove the performance standard required by clause 3.9.2B of the Rules for identifying dispatch intervals that have been affected by manifestly incorrect inputs. In particular, NEMMCO proposed that clauses 3.9.2B(j) and (m) be removed from the Rules and clause 3.9.2B(k) be amended.</p>
<p>
NEMMCO also requested that this Rule change proposal be &ldquo;expedited&rdquo; under section 96 of the National Electricity Law (NEL) for the following reasons:</p>
<ul>
<li>
this Rule change proposal would remove a performance standard that is not achievable;</li>
<li>
this Rule change proposal would have no effect on market operation or performance; and</li>
<li>
it discussed the issue with industry representatives who participate in the Dispatch Pricing Reference Group (DPRG), which supported NEMMCO&#39;s Rule change proposal provided the requirements for NEMMCO to review and report on the performance of the automated identification process in clauses 3.9.2B(k)and (l) remain.</li>
</ul>
<p>
On 15 January 2009, the Commission published a notice under sections 95 and 96 of the NEL commencing initial consultation on this Rule change proposal and advising of its intention to expedite the Rule change process on the ground that it is non-controversial, subject to the receipt of written objections.</p>
<p>
In relation to the Rule change proposal, the Commission invited interested parties to provide written objections to the expedited process by 30 January 2009 and submissions by 13 February 2009.</p>
<p>
No objections or submissions were received.</p>

On 26 February 2009, the Commission gave notice under sections 102 and 103 of the National Electricity Law (NEL) making the National Electricity Amendment (Removal of Performance Standard for Identifying Manifestly Incorrect Inputs) Rule 2009 No. 5 and the corresponding Rule determination. This Rule was made under an expedited process in accordance with section 96 of the NEL.</p>
<p>
The Rule change:</p>
<ul>
<li>
removed the requirement for NEMMCO to design the automated procedures to a performance standard, so that at least the majority of dispatch intervals subject to review are found either to: have had manifestly incorrect inputs; or be the result of the dispatch algorithm being run with correct inputs immediately after being run with manifestly incorrect inputs (by removing clause 3.9.2B(j) from the Rules);</li>
<li>
removed the requirement for NEMMCO to have regard to the performance standard under clause 3.9.2B(j) when it reviews the effectiveness of the automated procedures (by amending clause 3.9.2B(k) of the Rules); and</li>
<li>
removed the requirement on NEMMCO to carry out a review of the automated procedures if a report conducted by NEMMCO under clause 3.9.2B(l) on the effectiveness of the automated procedures demonstrates that these procedures have not achieved the performance standards (by removing clause 3.9.2B(m) from the Rules).</li>
</ul>
<p>
The Rule commenced on 27 February 2009.</p>
