Despite the progress made, excess demand over supply remains a pressing concern

…with excess demand above its 2019–2021 average

Demand remains greater than supply…

Excess demand is compensated for by load reductions + increased imports + open-cycle gas turbines

There has been a decline in the compensatory load, driven by the reduction in excess demand

The more sustained decline in the compensatory load has been fuelled by the decline in excess demand over supply

The decline in excess demand has been driven by a sharper and sustained decline in demand relative to the increase in supply
