Our verdict on the gas reservation policy - Grattan Institute

Grattan Institute has released an assessment of Australia's domestic gas reservation policy, which requires liquefied natural gas exporters to reserve a portion of their production for the domestic market. The institute has issued a verdict on the policy's merits and drawbacks, though the specifics of that verdict are not detailed in the headline or summary provided.

Where this fits

This story bears directly on grid reliability and the hidden cost of a renewables-heavy transition. Gas is the firming source that smooths the gap between weather-dependent wind and solar output and actual demand. A reservation policy that constrains gas supply or raises its cost undermines the one firm dispatchable technology Australia is currently building at scale to support renewable variability. The policy sits at the intersection of two pressures: the need to keep gas available and affordable for grid stability, and the political demand to limit export volumes. That tension is real, and Grattan's verdict on where the balance should sit shapes how well-resourced Australia's grid firming will be.

What it means

If reservation reduces gas supply or raises domestic prices, grid operators will have less reliable and more expensive firming available at the exact moment wind and solar deployment is accelerating. That leaves Australia with two bad options: pay more for gas, or accept greater reliance on imports and less control over grid security during periods of supply stress or geopolitical tension. The underlying problem remains unspoken: Australia is building a grid that depends on weather and on gas, when the lowest-emission firm power, nuclear, is legally off the table.
