The Central-West Orana Renewable Energy Zone (REZ) Transmission Project will build new high-capacity transmission lines, energy hubs and supporting infrastructure to transfer power generated by solar and wind projects to electricity consumers. The new infrastructure is expected to be operational by 2028 and will initially unlock up to 4.5 gigawatts of new network capacity.
