About high energy demand spikes
The National Electricity Market - NEM (NEM) is our central energy system, comprised of five physically connected states on the east coast of Australia. Electricity for the central energy system is generated (by generators such as wind farms or coal stations) and delivered by energy networks (distributors) via high voltage and lower voltage regulated energy networks or as we commonly refer to them as the "poles and wires". From there energy retailers, such as Enova Energy then retail electricity to households and businesses, with a variety of customer services, offers and products to suit their needs.
At times, the networks and the NEM central energy system (often referred to as 'the grid') experience large, synchronised surges of energy consumption.
When this occurs, increased energy generation is required to supply the central energy system with enough energy to meet Australia's power needs.
