The generation of the required resources for ‘next day public’ Energy and FCAS bid data in ez2View (Bid Details Widget) was delayed this morning. The cause was related to the database schema updates for MMS v5.3 but has now been resolved.

As part of the AEMO 5.3 data model release, we will be undertaking some database migration work on the real-time hosted MMS. We do not anticipate any interuption to the real-time data feed but some recent history in the follwoing tables will be temporarily unavailable:

PREDISPATCHLOAD
PREDISPATCHCONSTRAINT
PREDISPATCH_FCAS_REQ
DISPATCH_FCAS_REQ
DISPATCHCONSTRAINT
P5MIN_CONSTRAINTSOLUTION
P5MIN_UNITSOLUTION
SPDCONNECTIONPOINTCONSTRAINT

Due to a database issue related to the MMS 5.3 update, the NemPrices widget was unavailable and/or showing stale dispatch intervals from 10:10 NEM time through 11:10 NEM time.

This problem has now been resolved, but you may need to click the “refresh” button on the NemPrices widget in ez2view to get the latest data.

Due to an apparent data gap caused by a new unit in the next day public bid files as produced by AEMO for trading day 2024-03-04, all FCAS bids displayed in ez2view may have been incomplete, slow to load, or not visible at all in ez2view this morning.

This has now been resolved.

From midnight on Saturday Feb 3rd through approx 7:45am NEM time our Trends engine which provides functionality that backs NEMReview online and Trends editor in ez2View (amongst other things) was unavailable.

The issue was caused by an upstream data provider fixing a typo in a single entry, which led to a duplicate data error at our end, which in turn caused the trends engine to fail to start up.

We apologise for the downtime and we are investigating ways to be more resilient to this kind of failure in the future.
