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

Victoria has revealed the cost of a new transmission link designed to connect renewable energy zones to the grid. The Australian reported the figure but the article provided to us does not include the specific cost amount, timeline, or capacity details needed to assess the scale of this project against Victoria's broader transmission build.

Where this fits

Transmission overbuild is the hidden cost of a renewables-only grid. Every megawatt of intermittent solar and wind requires firm backup power (gas) and redundant transmission to move weather-dependent output across distance. This Victoria project is another data point in the pattern: the per-megawatt-hour cost of renewables looks cheap until transmission, firming plant, and spare capacity are added to the ledger. That total-system cost is rarely front-loaded in policy announcements.

What it means

Australia is committing to a grid design that requires constant transmission expansion to shuffle variable output. Each project locks in higher capital costs, longer build timelines, and continued dependence on gas for reliability. A firm, energy-dense alternative, nuclear, would require far less transmission redundancy and no firming plant, but remains banned by law. Victoria's transmission bill is a direct cost of that regulatory choice. Until the full cost stack of renewables-only (transmission, firming, storage, critical minerals, China supply-chain risk) is published alongside project budgets, Australian voters cannot weigh the real price of the path they are being asked to fund.
