Electricity Transmission Line Voltages and Locations in New South Wales

New South Wales electricity transmission lines with voltage ratings from 19.1 kV to 500 kV. The dataset is maintained by Spatial Services, a business unit of the NSW Department of Customer Service, and was initially published in February 2020. It includes line geometries aligned with defined administrative spatial datasets.

Use Cases

• Analyze spatial distribution of high-voltage (e.g., Line500kv, Line330kv) versus lower-voltage (e.g., Line19.1Kv) transmission corridors across NSW.
• Model proximity of new developments to different voltage line features (Line132kv, Line66kv) for risk assessment and planning.
• Update administrative maps and applications by integrating changed line geometries or names provided by data contributors.

Strengths

• Includes eight specific voltage classifications for transmission lines, from 19.1 kV to 500 kV.
• Line geometries are aligned with authoritative Spatial Services Defined Administrative Data Sets.

Limitations

• The dataset uses the GDA94 spatial reference, which is noted as incompatible with newer GDA2020 environments without transformation.
• Specific row counts, update frequency details, and data currency beyond a nominal '01/01/3000' date are not provided.
