Western Australia names Clean Energy Link – East contractors to unlock 2.3GW of solar and wind - PV Tech

Western Australia has named contractors for the Clean Energy Link project, a transmission corridor designed to connect 2.3 gigawatts of new solar and wind capacity from regional areas to load centres. The project is being positioned as essential infrastructure to unlock renewable generation across the state.

Where this fits

This is a whole-system cost story masked as a generation story. The 2.3 gigawatts of solar and wind are weather-dependent; firm power must back them, and the transmission backbone to move intermittent output across the state adds capital cost that does not appear in the per-megawatt-hour headline. The Unprepared angle sits here too. The panels, inverters, and batteries that will fill this corridor are manufactured almost entirely in China, on coal-fired grids. Western Australia is outsourcing both the hardware supply chain and the emissions accounting to a strategic rival, while forgoing the firm, long-lived, low-material alternative that is banned by law in Australia: nuclear.

What it means

Australia is building the right transmission, but in service of the wrong generation mix. A firm power backbone, whether gas or nuclear, would need less overbuild of cables and substations, because output is not weather-hostage. The real cost of this project is not the contractors' fees; it is the solar panels themselves, sourced from China's coal belt, and the gas plants (or future battery fleet, equally China-dependent) that will run whenever the wind does not blow. Australia is outsourcing energy security to the supply chain it can least afford to depend on.

By the numbers

Taking the article's figure of 2.3GW of solar and wind, at indicative Australian build costs:
What it costs to buildA$2.5bn–A$3.7bn

at ~A$1100–1600/kW installed. Source: CSIRO GenCost 2024-25. Indicative.

What it generates~4.8 TWh/yr

at a ~24% capacity factor, and only when the sun shines, so it still needs firming.

Money into China's economyA$2bn–A$2.9bn

~80% of modules are China-made. Source: IEA solar supply-chain data.

The same money in nuclear0.2–0.4 GW

enough for 2–3 TWh a year of firm, always-on power, generating for ~60 years. Source: CSIRO GenCost 2024-25 (A$8.5–13.2bn/GW), IAEA capacity factor.

Figures are indicative conversions from the article's stated quantity using published cost, material and capacity factors (CSIRO GenCost, BNEF, IEA, IAEA). Ranges, not precise forecasts.

The bigger picture

Energy security is national security. This connects to the wider case at Unprepared: Australia's dependence on a strategic rival, and how ready it is for the world that is coming.
