Victoria’s renewables transmission link cost revealed - theaustralian.com.au

Victoria has revealed the cost of a major transmission link designed to connect renewable energy sources to the grid. The Australian reported the figure, but the article provided does not specify which transmission project, which route, the cost per kilometre, the timeline, or how the expense compares to initial estimates or to similar projects interstate.

Where this fits

Transmission is the invisible tax on renewable energy. Every megawatt of wind and solar requires new poles, wires and substations to reach load centres, and these costs are rarely front-loaded in the business case. This project illustrates the whole-system cost of the renewables transition: the grid itself must be rebuilt, often across hostile terrain, before a single panel or turbine generates electricity. The bill falls on consumers and taxpayers.

What it means

Australia is building a dual infrastructure: coal and gas plants are being retired faster than dispatchable replacements are commissioned, while the transmission network sprawls across greater distances to collect renewable energy from remote sites. Each kilometre of new line is a sunk cost that must be recovered. Without firm generation capacity (coal, gas, or nuclear) to anchor the grid and reduce transmission load during peak demand, the cost per unit of reliable electricity rises sharply. Victoria's transmission link is necessary, but it is also a symptom of an energy transition that has underestimated total system cost and extended the timeline for grid stability.
