Electricity Transmission Lines in New South Wales with Voltage Classes

A wire feature dataset for electricity transmission lines rated from 19.13kV to 500kV in New South Wales, Australia. The data is provided by Spatial Services, a business unit of the Department of Customer Service NSW, and is aligned with the national GDA2020 geodetic standard. It is updated upon notification from the Spatial Services Administrative Spatial Program and Geoscience Australia.

Use Cases

• Map high-voltage power corridors based on the listed voltage classes (e.g., 132kV, 330kV).
• Analyze infrastructure proximity for land development or environmental impact assessments based on line geometries.
• Model grid capacity and network planning using the spatial distribution of transmission lines.

Strengths

• Dataset is aligned with the national GDA2020 geodetic standard, improving positional accuracy and compatibility.
• Includes eight distinct voltage classes, from 19.1kV to 500kV, providing detail on transmission capacity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
