On Friday 27th May 2022 we upgraded the ‘Live Supply & Demand Widget’ – which we have been pleased to provide as a freely accessible source of supply/demand information for many years thanks to the sponsorship of RenewEconomy.
<< We’ll fill in this page with more details later>>
Early last week we made v10.3 of NEMwatch available to download for our existing clients. The release contained a bug fix to one of the pricing metrics along with some other minor tweaks to the interface. Just after release, the software was featured in some of the coverage of QLD’s heatwave that ended with prolonged extreme wholesale prices in the state.
The release of v10.3 corrected an issue that arose after the implementation of 5-minute settlement in October 2021, where the ‘cumulative price’ metric displayed was based on 30-minute intervals that were previously used in it’s calculations. This has now been fixed and the cumulative price is now calculated based on the market’s newly implements 5-minute settlement intervals. In addition to this, the release also included minor tweaks to some labels and colours in the main interface.
You can download the latest version of the software here.
Just as we had finished releasing these changes last week, Queensland was experiencing a heatwave which resulted in volatile prices and a load-shedding near-miss. Screenshots from NEMwatch were used on WattClarity to exhibit demand rising to peak levels last Tuesday evening. Meanwhile, our very own Paul McArdle was quoted in the Australian Financial Review’s coverage of the potential blackouts where he predicted a long run of extreme prices for the state that evening.
Behind the scenes, we’ve been working on an upgrade to the NEMwatchTM application for some time (you might have seen some early snapshots in articles like these on WattClarity®).

The month of January 2019 saw extreme temperatures registered across much of the Australian continent. As a result, high levels of electricity demand were experienced – and pushed electricity supply infrastructure (generation, and transmission/distribution) to the limit.
On Friday 25th January, journalists at the Australian reproduced of a snapshot from the NEMwatch widget showing the 17:40 dispatch interval (NEM time) on Thursday 24th January (with a couple artistic tweaks) – here’s a view of the print edition, with the full copy of the online article “Heat stress: power crisis hits home” here:

The first week of winter 2018 (Monday 4th June to Friday 8th June) saw a tight supply/demand balance in the NSW region of the NEM – with prices spiking near the Market Price Cap on Tuesday, Thursday and Friday, and various forms of demand response triggered as a result. Journalist at the Newcastle Herald wrote…
As noted here in this article on Wattclarity about the commencement of operations at what’s currently “the world’s biggest battery” in South Australia, we have upgraded the popular NEM-Watch Fuel Mix widget to show both sides of the battery operation.

One of our team members was surprised, last night (i.e. Friday 3rd June 2016) to see an old image of an old version of NEM-Watch (from way back in 2007) used to illustrate how Tasmania would normally be interconnected to the mainland by the sub-sea HVDC (high-voltage direct current) link connecting into the Latrobe Valley in Victoria….
