Evolution – of the RenewEconomy widget

In the following table we have provided a (reverse-chronological) listing of some of the enhancements made to this widget over time:



 November 14, 2022

Supply from VRE (Variable Renewable Energy) and supply from renewables (VRE plus hydro), as percentages of all supply, is included for the NEM (National Electricity Market) and WEM (Western Australia’s Wholesale Electricity Market).

 November 7, 2022

We upgraded the widget’s small-scale solar PV data source. It now presents AEMO small solar estimates for NEM regions. The APVI’s estimates for WA are maintained.

May 27, 2022

We released an upgraded version of the widget – including with these linked pages here on WattClarity that we’ll be able to keep updated as more questions emerge from users of the widget.

This was noted in this short update on the NEMwatch portal.

July 2021

We enhanced this widget to select a newer APVI data feed – which was both:

1)  More reliable; and also

2)  More accurate (going some way to alleviating these opacity challenges).

Whilst doing this, implemented a number of other enhancements to deliver more value in the software.

Late 2017

In late 2017 we re-built the widget, in conjunction with first operations of the Hornsdale Power Reserve :

1)   Which was also known for a time as the “world’s biggest battery”; and

2)  Which began operations on Saturday 25th November 2017.

Because of the ‘two sides’ of the battery (i.e. Supply and Demand) we saw this as an opportunity to upgrade this widget to make it a ‘Supply and Demand’ widget and hence provide an enhanced level of clarity and transparency to our users – as discussed here on the NEMwatch portal.

Also worth noting that the Hornsdale Power Reserve battery gets its own widget at the bottom of the Neoen website here.

March 2015



This widget was updated (March 2015) to include “APVI Small Solar”, which is the estimated production from small-scale (i.e. predominantly rooftop) solar PV – described in the FAQs here.

Further information here, on the NEMwatch portal.


This widget was first developed in 2015, and has been through several upgrades since that time (with some of the history described here).

Don’t forget that this widget is only one of the ones we have developed over time – some of the others are discussed here.
