Victoria backs away from renewable transmission projects - MacroBusiness

Victoria's state government is pausing or backing away from renewable transmission projects, according to MacroBusiness reporting. The pullback reflects cost pressures and delays in the buildout of network infrastructure needed to connect wind and solar farms to the grid.

Where this fits

Transmission overbuild is one of the hidden costs of a renewables-led grid. Each megawatt of wind or solar requires not just the generation asset but also dedicated poles, wires and substations to move that weather-dependent power to load centres, often over long distances. When those costs mount or timelines slip, governments retreat. A firm, dispatchable power plant sits on or near demand and needs no such grid reinforcement; nuclear plants occupy a footprint one-hundredth that of equivalent solar farms and require no transmission sprawl to reach the same output.

What it means

Delays in transmission construction mean less renewable capacity can be absorbed onto the network, pushing back the timeline for decarbonisation and leaving gas plants online longer. It also locks in a higher whole-system cost than the headlines suggest: the $X-per-megawatt price of a solar panel tells you nothing about the cost of getting that power to your suburb. Australia's transition timeline is now hostage to construction costs and supply-chain bottlenecks in transmission steel and semiconductors. A firm, zero-emission alternative, nuclear, remains legally barred, despite needing none of this transmission apparatus and delivering constant output regardless of cloud cover or wind.
