Transgrid has pinpointed remote inland renewable energy zones (REZs) as essential to meeting New South Wales’ (NSW) growing electricity demands amid a shift to renewable energy. With coal expected to supply less than 20% of the state’s power by 2033, Transgrid forecasts a three to fivefold increase in renewable capacity by the decade’s end.
The latest Transmission Annual Planning Report (TAPR) highlights rising electricity demand, increased volatility, and a decline in minimum grid-supplied power in NSW. While offshore wind was considered, uncertainties have shifted focus to inland REZs in areas like Broken Hill, Noona, and the state’s northwest, known for their strong solar and wind resources.
Developing these REZs will require extensive transmission infrastructure, but Transgrid is also exploring non-network solutions, including large synchronous condensers and up to 5 GW of grid-forming batteries, to support system strength.
