Energy data from the Australian Energy Market Operator
This graph shows the amount of energy being contributed into the grid by each type of fuel source or generator. It also shows the total which, essentially, amounts to energy being demanded of the grid at any given time.
Rooftop solar does not feature in the AEMO dispatchable/SCADA data used for the rest of the sources. This data is merged for display here, however, in order to create a more complete representation of supply.
More detail may be seen for each type of generator on its individual page: Fossil Energy, Hydro Energy, Wind Energy.
