Going full hybrid: Massive, $2 billion solar and battery proposed at site of newly expanded wind farm - Renew Economy

A $2 billion solar and battery complex has been proposed at a site in Australia where a wind farm was recently expanded. The project aims to combine wind, solar and storage at a single location.

Where this fits

This is a cost story disguised as an efficiency story. Co-locating wind, solar and battery at one site looks sensible on paper: shared grid connection, simplified planning, one transmission route. But the $2 billion figure, for a solar array and battery system at a single site, illustrates the escalating capital cost of building a renewables-plus-firming grid. The battery is there to cover the gaps when wind and solar are both low. That is a whole-system cost the headline does not flag: you are building three assets (wind, solar, storage) where one firm power plant would do. The article does not disclose the nameplate capacity of the battery, the hours of storage, or the gas backup still needed on low wind-low solar days. Those omissions matter because they hide the true overbuild.

What it means

Australia is locking in a model that requires massive capital deployment, a supply chain owned by China, and perpetual gas firming for reliability. A nuclear plant at the same site would deliver the same annual emissions reduction, with lower total-system cost, no weather dependence, no critical-mineral vulnerability, and no need for gas. Instead, the regulatory bar for nuclear remains a ban, while renewable-plus-storage projects of this scale are approved as the path forward. This is a choice, not an inevitability, and it is a choice that leaves Australia dependent and unprepared.
