Our Live Generation Widget, as seen on RenewEconomy

Thanks for following through on the link provided in the Generation By Fuel Type widget (which we developed with the support of RenewEconomy).

Here’s that widget again, for your convenience:


We are pleased to be able to work with the RenewEconomy team to assist RenewEconomy readers to understand how much renewable generation is currently contributing to electricity supplies in the main electricity grids across Australia.



This widget was first developed in 2015, and has been through several upgrades since that time.

We would like to continue developing this widget over time – and we would be grateful for whatever feedback you can provide us to guide its ongoing development.



It shows, for each region of Australia’s National Electricity Market (NEM) and the other main grids across Australia, how much electricity is being generated by each fuel type, using data published by several organisations:

In the east, the NEM covers only ½ of the Australian land-mass but accounts for roughly 90% of electricity consumed across the country.

In the west, the WEM is the largest grid (in energy terms) in the rest of the country, supplying the city of Perth and surrounding areas of south-western WA.

The widget shows an instantaneous rate of production (i.e. MWh per hour – or simply MW) and utilises three sources of data:

  1. Except where otherwise noted on the chart and in the table, data is generation SCADA data published by AEMO (for Scheduled Generators, plus some others), and aggregated to fuel type by us.
  2. To show a fuller context of consumption, this Generation by Fuel Type widget was updated (March 2015) to match NEM-Watch v10 in also including “APVI Small Solar”, which is the information derived by the Australian Photovoltaic Institute (APVI) and published here:

  1. To show a fuller picture of the fuel source mix used in electricity supply across the country, the widget was also updated (July 2015) to include the similar data for the South-West Interconnected System (SWIS) in Western Australia – using data published by the Independent Market Operator (IMO-WA).

The NEM operates in Australian Eastern Standard Time (i.e. no daylight savings – so Brisbane time) and this is the time stamp given to the AEMO data displayed. Mouse-over the APVi or IMO data to see its individual time-stamp.

All data is shown as close to your current viewing time as possible.



This widget is one of many charts provided within our NEM-Watch™ software application.

NEM-Watch™ is a dashboard application that most of a diverse range of clients run 24×7 to enable them to keep an eye on how the NEM is operating.

In this portal here, we explain how clients use NEM-Watch to assist with:
(a) Situational Awareness
(b) Active Analysis
(c) Education and training; and
(d) More effective communication

NEM-Watch™ is just one of the software products developed by us at GLOBAL-ROAM Pty Ltd (a company focused on making the complexity in energy markets understandable to a broad range of people since 2000).



Perhaps we can help you through the development, for you, of a widget that focuses on a particular point of interest you have in the competitive energy market?
