Price Revision Reports

AEMO has established procedures to identify Dispatch Intervals that have been affected by manifestly incorrect inputs to the Market Dispatch Engine (NEMDE). National Electricity Rule 3.9.2B(g) requires AEMO to publish a report for each instance where the procedures lead to dispatch interval prices being replaced. This Rule came into effect from 1 June 2006.

For further information contact AEMO’s Information Centre.

 

Reports on Directions

The introduction of the Direction Review changes to the National Electricity Rules, on 9 December 2002, require AEMO, pursuant to clause 3.13.6A, to publish reports providing background information related to directions issued to Registered Participants.
