Earthworks begin on key substation for inland transmission line that could unlock Queensland renewable riches - Renew Economy

Earthworks have begun on a major substation for an inland transmission line in Queensland designed to carry renewable energy from inland generation sites to the coast. The project is part of the grid infrastructure buildout needed to support the state's renewable development zones.

Where this fits

This is a transmission-cost story dressed as a renewable-opportunity story. The article does not quantify the substation cost or the full inland transmission build, but the headline's framing, unlocking renewable "riches", obscures a hard fact: Queensland's renewable zones are inland, far from load centres. Connecting them requires hundreds of kilometres of new high-voltage lines, substations, and synchronous condensers. This is not a hidden cost. It is the cost. A firm, energy-dense alternative like nuclear can be sited near load, near cooling water, near population. It does not require a transmission overbuild. Every dollar spent on this inland grid extension is a dollar not spent on firm generation or on the sovereign industrial capacity Australia will need if China restricts rare-earth or silicon exports.

What it means

Australia is locking in a grid architecture that is transmission-heavy, weather-dependent, and reliant on China for the panels, inverters, and batteries that make it work. The substation is real infrastructure. So is the cost. And so is the bet: that weather-dependent generation from remote inland sites, firmed by gas and batteries whose supply chains run through Beijing, is cheaper and faster than deploying firm nuclear capacity now. The evidence for that bet keeps shrinking.
