Whenever economic islands are present, a bar graph will appear showing the supply and demand balance for each economic island. The first bar shows the sum of demand and net export, the second bar is available generation and the third is instantaneous reserve plant margin (IRPM).
Current economic islands.
Clicking the graph icon shows a trend of recent demand, available generation and IRPM. The graph is discontinuous because the economic island has not existed for all periods.
