Dispatch and forecast data across all products appears out of date, due to an apparent upstream data issue at AEMO. We are aware and monitoring the situation.

We will update this status page as more information becomes available.

Update 14:15pm: AEMO market data is up to date again and dispatch is proceeding. We are checking for any flow-on issues.

Refer to this Watt Clarity Article for more information on the disruption.

At approx 5.10am on Sunday August 11, the web service that hosts our “Trends” engine was restarted automatically, but failed to successfully start up due to some underlying source data changes.

Trends provides functionality that backs NEMReview online, the Trends widgets ez2view and many other services. These were out of service since 5.10am. Users might have seen a 500 error code, or an error page that says “app failed to start”.

Service was restored at approx 8:25am. We apologise for the downtime. This has now been resolved, but we will examine the causes in more detail to avoid a recurrence of this kind of outage.

We are aware of missing bid data for both Energy and FCAS in ez2view for trading day 2024-07-26. Both ENERGY and FCAS market bids for this day were either incomplete, slow to load, or not visible at all in ez2view this morning.

This has been caused by a validation error in bids for this trading day after units related to the BDU / IESS transition have become deregistered.

We have resolved the bids issue manually and will be looking into the details to avoid this reoccurring, thanks for your patience. There may be some inconsistencies remaining for these deregistered units which we will also address in due course. For reference the now-deregistered units affected were: BHBG1, BHBL1, WANDBG1, WANDBL1

Start time: 10pm 9 July 2024 End time: 9am 10 July 2024

Due to an internal service failure, certain data was not being calculated overnight. This missing data affected these services:

• NemPrices widget in ez2view was unable to get new data - and reloading it would have shown an infinite loading screen.
• ez2View would have been unable to get MTPASA DUID Availability data which affects the MTPASA DUID Availability, ForecastConvergence and GeneratorOutages widgets.

We have now resolved this issue.

Due to a unit that has newly registered in the 1 second FCAS markets, for trading day 2024-06-17, incomplete dispatch data led to a delay in this data being available. FCAS bid display in ez2view for this day may have be incomplete, slow to load, or not visible at all in ez2view this morning.

We have now resolved this issue. ENERGY market bids were unaffected.
