RESERVE NOTICE MT PASA PUBLICATION 6 February 2018

AEMO ELECTRICITY MARKET NOTICE

The MTPASA result published on 6 February 2018 shows Low Reserve Conditions (LRC) in South Australia and Victoria for summer 2017-18, 2018-19 and 2019-20. Please note that MTPASA informs the market of potential LRC's to allow the market to respond in the first instance, potentially avoiding the need for any market intervention or direction from AEMO. As such, the MTPASA forecast does not incorporate many of the actions taken by AEMO to improve reliability this summer.

This notice supersedes Market Notice 61035 published on 30 January 2018.

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
