Before this change to the Rules there was no provision for the correction of these specific dispatch pricing errors, allowing them to flow through to the spot market settlement process, and to persist as market price signals.

Background

On 15 February 2005 NEMMCO submitted to NECA a proposal to amend the National Electricity Code to allow NEMMCO, in specified limited circumstances, to revise market prices after identified manifestly incorrect inputs into the dispatch system. NECA conducted a first round consultation on this proposal - submissions closed on 21 March 2005.

Under the National Electricity Law (NEL) transitional provisions, consideration of this Rule proposal became the Commission's responsibility on 1 July 2005.

The Commission decided to dispense with the first round consultation steps under the Rule making process in respect of this Rule proposal because those steps duplicate processes already carried out under the National Electricity Code. The Commission determined therefore to progress this Rule proposal to the stage of issuing a draft Rule determination.

The Commission issued a final determination on the proposed Rule.
