RESERVE NOTICE MT PASA PUBLICATION 21 November 2017
The MTPASA result published on 21 November 2017 shows Low Reserve Conditions (LRC) in South Australia for November 2017, Summer 2017-18, March 2018, Summer 2018-19 and March 2019, and in Victoria for November 2017, Summer 2017-18, March 2018, November 2018 and Summer 2018-2019. AEMO will continue to monitor the situation and take appropriate actions, if necessary.
To view the summary of MTPASA results for the next 24 months, visit AEMO's website at http://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data-dashboard and click on the 'Medium Term Outlook' tab.
This notice supersedes Market Notice 59898 published on 14 November 2017.
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 capacity reserve conditions over a two year period.
AEMO may apply probabilistic studies such as Energy Adequacy Assessment Projection (EAAP) to confirm the LRC findings of MTPASA before intervening in the market.
For more information about how AEMO implements the reliability standard, please view the Reliability Standard Implementation Guidelines (RSIG) available on AEMO's website at
