75088RESERVE NOTICE31/03/2020 03:52:39 PM
RESERVE NOTICE MT PASA PUBLICATION 31 March 2020
The MTPASA result published on 31 March 2020 identifies no Low Reserve Conditions.
Please note that MTPASA informs the market of potential reliability issues to allow the market to respond in the first instance, potentially avoiding the need for any market intervention or direction from AEMO.
For further information, please refer to:
https://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data/Market-Management-System-MMS/Projected-Assessment-of-System-Adequacy
This notice supersedes Market Notice 75014 published published on 25 March 2020.
Background
As part of a broader process of implementing the reliability standard, AEMO runs the Medium Term Projected Assessment of System Adequacy (MTPASA) process weekly to forecast expected unserved energy levels over a two year period. If the expected annual unserved energy exceeds the maximum level specified by the Reliability Standard, a Low Reserve Condition is identified.
For more information about how AEMO implements the reliability standard, please view the Reliability Standard Implementation Guidelines (RSIG) available on AEMO's website at
https://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Planning-and-forecasting/Reliability-Standard-Implementation-Guidelines
