(E)  More information about this widget

This page (and pages linked below) have been prepared to answer Frequently asked questions we have received

on the Widget: Brief Notes, and Links
About Supply and Demand

On this linked page here, we explain why supply and demand need to be considered as a pair at the same instant in time in order to gain a true picture of what’s happening in the electricity market.

Cadence, Timestamps, and Data Points

We’ve prepared this page here to provide an explanation about the different types of data included in the RenewEconomy widget, including:

1)  Where it comes from (and what it means);

2)  How frequently it is measured … or estimated;

3)  How it is aggregated.

Frequently asked Questions (FAQs)

We’ve appreciated the opportunity to enhance visibility and understanding of the NEM’s energy transition via this widget for many years.

Over that time (through the Feedback button, or otherwise) we’ve frequently received a number of the same questions, again and again … for instance:

Q1)  Where is NT, or the ACT?

Q2)  What is ‘demand the AEMO doesn’t see’?

Q3)  What happens, when Supply > Demand (or Demand > Supply)?

Q4)  Why can’t I see percentages here?


In this linked Frequently Asked Questions page, we have provided detailed explanations to these and other questions, so we would suggest you check these first, before asking the same question again!

Evolution of this Widget

On this page here we have provided a chronological record of the progressive enhancement of this widget.

About our Widgets

This widget is one of a number of widgets we have developed over the years… and, indeed, through our ez2view software clients can make their own embeddable time-series widgets.

Supply and demand for electricity are inextricably linked on an instantaneous basis – hence the combination of these two data points in the RenewEconomy widget.

In a similar way, there is a tight relationship between weather patterns (and particularly temperature) and levels of electricity consumption. That’s the reason we worked with Energy Consumers Australia to put together the “ECA Widget” described here.

Some of the other widgets are discussed here.

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?

If so, please call us on +61 (0)7 3368 4064 to discuss.
