Distributed energy resources are challenging distribution networks
The rise of the ‘prosumer’ and distributed energy resources (DER).
A global energy transition is underway that supports a low-emissions future. This is in line with the Paris Agreement, which aims to limit global temperature change this century to well below 2 degrees Celsius. In the electricity sector, one aspect of this transition is the rise of the ‘prosumer’, a customer that both consumes and produces electricity. Prosumers use distributed energy resources (DER) — including rooftop solar photovoltaic (PV) systems, behind-the-meter batteries and electric vehicles (EVs) — to generate, consume and manage electricity at their premises. Electricity they do not consume may then be fed back into the grid.
Australia is already a global leader in rooftop PV installations. Currently, Australians have installed over 2.3 million rooftop PV systems, equating to around 23% of households1. CSIRO, the Australian Government’s scientific research agency, forecasts that over 40% of Australian customers will use on-site DER by 2027. This includes 29 gigawatts of PV and 34 gigawatt hours of behind-the-meter batteries.
