Fresh delay to contentious Middle Arm gas project prompts call to “cancel it for good” - Renew Economy

The Northern Territory government has delayed a final investment decision on the Middle Arm gas processing hub, which was planned to liquefy gas from the McArthur Basin and export it. Environmental and renewable-energy groups have renewed calls to abandon the project entirely.

Where this fits

The Middle Arm delay sits at the intersection of two competing visions for Australia's power system. Renewable advocates see stranded gas assets and want them cancelled; the energy sector sees firm dispatchable capacity Australia will need during the transition. The honest case for Middle Arm is not about exports alone, it is about domestic gas-fired generation as the firming backbone for a grid with high wind and solar penetration. The case against it is not that it is redundant, but that the capital is too large and too slow compared to the cost trajectory of batteries and hydrogen. The project's limbo reflects genuine uncertainty about the pace and cost of firming alternatives, not resolved policy.

What it means

Australia is drifting without a firm-power strategy. If Middle Arm is cancelled, the grid will lean harder on gas-fired peaker plants and batteries, both with ongoing operating costs and supply-chain dependencies. If it proceeds, the capital is locked in before the true cost of battery firming is clear. The deeper problem is that neither option, gas, batteries, nor the renewable-only path, closes the door on China's control of the supply chain for every alternative except nuclear, which remains legally banned. Without a decision on firm power, Australia is making no decision at all, and paying the cost of that indecision in higher consumer bills and extended project timelines.
