“Demand Response” (sometimes called Demand Side Response) is a term given to a range of activities undertaken by electricity users, or people acting on their behalf, to temporarily curtail consumption (or effectively lower net consumption by use of onsite generation) in response to some form of commercial incentive.
This curtailment activity might be taken at times of tight supply/demand balance (and/or high spot prices) in the wholesale electricity market, or at times of high network loading.
In this 2011 report of the North American Electricity Reliability Corporation (NERC) they provided a very useful framework for understanding different categories of demand response – figure 1 on page 9.
Because of its usefulness, we’ve translated this diagram into an indexing method – please click on a box below and we’ll direct you to a page that provides more information about each category of demand response, but in the context of the Australian National Electricity Market (NEM).

Because the curtailment activity is temporary, “Demand Response” fits into a broader category of “Demand Management” that also includes permanent demand pattern changes through practices such as energy efficiency – as shown above.
There are a number of different mechanisms by which “Demand Response” can work in Australia’s National Electricity Market (NEM). In this site, we seek to explain all the different methods by which Demand Response is, and has been, used in the NEM (plus some proposed new methods, as well). It provides a collation of materials relating to Demand Response that we have found in our travels.
Hence, if you see something we have missed, please let us know so we can continue to improve this service.
