The Energy Corporation of NSW (EnergyCo) has increased the amount of renewable generation and storage that can connect to the transmission network in the Central-West Orana Renewable Energy Zone (REZ) to 7.7 gigawatts (GW).

In a statement, EnergyCo said the increase in transfer capacity was formalised under the Central-West Orana REZ access scheme via a transfer capacity determination.

The network capacity of 4.5 GW allows for 7.7 GW of renewable energy and storage projects to connect as wind, solar, and battery projects operate at different times of the day.

EnergyCo said the capacity increase does not expand the scope of the Central-West Orana REZ transmission corridor. Extensions are not currently proposed and would be subject to separate planning and regulatory approval processes.
