Origin dumps massive NSW wind farm over soaring costs - The Australian

Origin Energy has abandoned a major wind farm project in New South Wales, citing soaring construction costs. The project, which had been announced as part of the company's renewable energy expansion, is no longer viable at current economic conditions. The decision reflects broader cost pressures now materialising across Australia's electricity transition.

Where this fits

This is a cost story, and it exposes a core claim of the energy transition: that renewable projects pencil out. When a large, utility-scale wind farm no longer stacks financially, it signals that either input costs have risen sharply, or the wholesale electricity price assumption underlying the business case has fallen. Either way, it reveals that the stated cost of renewables, often quoted as the cheapest per megawatt-hour, masks a whole-system problem. Firming, transmission, curtailment, and project slippage all add to the real cost of a renewables grid. A firm, dispatchable alternative like nuclear would not face this revenue volatility.

What it means

Origin's retreat signals that Australia's renewable build is now hitting hard economic constraints. This matters for national energy security, not just shareholder returns. A slower renewable rollout means the grid depends longer on gas for firming, locking in ongoing fuel cost exposure and geopolitical vulnerability to gas supply shocks. More broadly, it highlights that Australia is betting its electricity future on technologies whose economics depend on perfect market conditions and stable wholesale prices. The alternative, firm, domestically fueled nuclear power, remains banned by law, leaving Australia with no policy option to accelerate low-emissions, low-cost, resilient electricity supply.
