Title - Retrospective revision of Electricity dispatch and trading price in accordance with market suspension pricing schedule due to South Australia market suspension
Change Starts-30/09/2016 13:00 AEST & Ends 01/10/2016 17:00 AEST
Description-AEMO has started to determine market prices that apply for the period of SA suspension (from 16:18 AEST28/09/16) These prices will be progressively loaded into AEMO's Market Systems and published to via Data Interchange and to AEMO's public website.
Timing - AEMO expects to start this process today and continue as market price calculations are progressively finalized for period of market suspension. AEMO will confirm with participants once this process has concluded, and anticipates this to be within 1 business day of the market suspension being lifted
Impact & Requirements - If you have downstream processes or systems that may have used existing prices please review to determine any potential impact. As this is a rare event AEMO would like to make sure participants are aware of these changes to market data and that this will result in a large volume of retrospective price data being delivered over AEMO's Data Interchange systems. AEMO will be staggering these data updates to minimise any impacts on AEMO and participants systems due to data volumes. The updated reports will modify existing dispatch and trading prices (previously indicated as firm) in participants Electricity Data Models. AEMO is also planning to rerun our prudential systems to account for updated prices once market prices are loaded. Which will result in updated prudential information being published. While we do not expect any issues, in relation to participants who have a local Electricity Data Model, given the rarity of this event participants are encouraged to validate any impacts on their own downstream systems that may rely on this information
