Renewable Energy Zones in Australia: design and grid notes for engineers
Reviewed by Tom Sullivan

First reported on New Civil Engineer
30 Second Briefing
New South Wales is rolling out Renewable Energy Zones (REZs) to replace ageing coal plants, clustering large-scale wind, solar and storage projects where grid capacity can be efficiently reinforced. Engineers are being redeployed from coal and gas infrastructure into REZ planning, high‑voltage transmission design and grid‑forming inverter integration, with a strong focus on connection studies and system strength. The shift is driving demand for civil and geotechnical works on new substations, access roads and foundations in remote sites, plus materials expertise for high‑temperature, high‑UV environments.
Technical Brief
- For similar large‑scale renewables clusters, early geotechnical corridor studies are becoming as critical as generation yield modelling.
Our Take
Among the 68 coal‑keyword pieces in our database, Australia features frequently in stories about grid transition rather than new coal capacity, signalling that New South Wales engineers working in Renewable Energy Zones are more likely to be redeployed from coal‑linked infrastructure than to expand it.
With many Infrastructure category items now tied to 2030‑type renewable targets, projects in NSW are under tighter delivery windows than traditional power schemes, which typically means front‑end engineering and grid‑connection studies need to run in parallel rather than sequentially.
UK‑based practitioners following New South Wales Renewable Energy Zones are increasingly referenced in our Sustainability‑tagged coverage as design exporters, suggesting that firms with experience on UK offshore wind and interconnectors may find a ready market in Australian transmission and storage design work.
