The map is not the grid

The NEM spot market assumes that electricity dispatch is about energy price alone. The article traces two catastrophic moments when that abstraction failed: the 2016 South Australia blackout, where physics outran the market model and the system collapsed in ninety seconds, and the 2022 energy crisis, where an administered price cap broke the link between cost and price, capacity withdrew, and operators resorted to manual dispatch across all five regions. Both events exposed a single fault: the market does not price or even see the synchronous properties, inertia, fault current, voltage stiffness, ride-through, that keep the grid stable in the first seconds after a fault. These properties historically came free with coal and gas plants. They are not traded.

Where this fits

This is a reliability story dressed as a market-design problem. The NEM's blind spot is structural: as synchronous plant retires and renewables replace it, the physics the market cannot see becomes the physics the grid depends on. Firming that physics, inertia, strength, ride-through, is a cost the headlines never count. A firm generator solves it by design. The cost of inventing synthetic solutions after the fact is higher, and the engineering is younger and less proven at scale.

What it means

A grid built on a market that cannot see half its own physics is a grid run by abstraction, not engineering. When the model and the machine disagree, an engineer takes over. Australia is building toward a state where that moment arrives more often, not less, because the replacement for retiring synchronous plant does not provide what the market was blind to all along.
