Huge landowner-led wind project seeks green tick, despite looming threat to transmission link - Renew Economy

A large wind project backed by landowners is seeking environmental approval despite concerns that the transmission network in its region may not have capacity to reliably export the power it would generate. The project appears to be proceeding on the assumption that grid connection will be available, even as the existing transmission link faces acknowledged constraints.

Where this fits

This is a textbook reliability problem baked into the renewables build-out. Wind farms are sited where the wind resource is good, not where the grid has spare capacity. Every major wind and solar project now discovers mid-development that transmission is the bottleneck. The cost of firming (gas backup to cover calm days) and of building new transmission lines to move weather-dependent power across long distances is not factored into the per-megawatt-hour cost of the panels or turbines themselves. That cost falls on the whole system, and on consumers. Firm generation, coal, gas, or nuclear, does not have this problem: it produces when needed, not when the weather permits.

What it means

Australia is now routinely approving renewable capacity ahead of transmission readiness, creating a mismatch between generation and delivery. If the transmission link cannot be upgraded in time, the wind farm's output will be curtailed, wasting capital and leaving the grid short of firm capacity at peak demand. The alternative, nuclear, would have sat on that same land, required the same connection, and produced firm power 24/7 without weather dependence or firming cost. The law forbids it. Instead, Australia is repeating the same pattern: cheap per megawatt-hour, expensive per megawatt of reliable grid capacity.
