Substations

OFFICIAL Change Notification: This item has been renamed from ‘Electricity Transmission Substations’ and its source data has been updated. Any maps or applications that use this item will need the layer re-added to continue accessing it. API links will need to be updated with the new link available through the item detail page. Current implementations will continue to work until 24 July 2026. For support, contact [DigitalAtlas@ga.gov.au.] ##### ##### Abstract Substations are facilities that convert, control, or transform high-voltage electricity supply. This dataset is part of the Electricity Infrastructure dataset which also includes power lines and major power stations. This dataset only includes substations that intersect with the associated ‘Power Lines’ dataset. ##### Currency Date modified: 19 June 2026 Modification frequency: As Needed ##### Data extent Spatial extent North: -9° South: -44° East: 154° West: 112.5° ##### Source information The Electricity Infrastructure dataset was compiled from publicly available data then validated with Esri World Imagery. For a detailed list of information sources, refer to the 'FEATURE_SOURCE' and 'ATTRIBUTE_SOURCE' attribution for each feature within the dataset attribute table. All spatial data and major non-spatial data sourced from a trusted third party and integrated directly into the dataset are detailed in the metadata statement, including required disclaimers and citations. Catalogue entry: [Electricity Infrastructure] Metadata statement: [Metadata statement] ##### Lineage statement This is an updated dataset of the Transmission Substations dataset. New features were added using the most current trusted public sources. See the Revision Dates and Descriptions section of the metadata statement for more information about this update. ##### Data dictionary ─────────────────────┬─────────────────────┬────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── Attribute name │Alias │Description ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── OBJECTID │OBJECTID │Identification number automatically generated per feature by Esri. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── SHAPE │Shape │The geometry of the spatial data automatically generated by Esri (point, polygon, line). ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── FEATURE_TYPE │Feature Type │Generalised classification of feature types. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── FEATURE_SUBTYPE │Feature Subtype │The feature type subtypes: │ │• Bulk Supply Point │ │• Sole Use │ │• Substation │ │• Subtransmission │ │• Switchyard │ │• Terminal │ │• Transmission │ │• Zone ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── FEATURE_NAME │Feature Name │Name of the facility. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── FEATURE_DESCRIPTION │Feature Description │Brief description of the feature type. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── STATUS │Status │A description of the feature’s status: │ │• Operational │ │• Non-Operational │ │• Under Construction ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── VOLTAGE_KV │Voltage_kV │The largest voltage of line (if multiple) connected to the substation (kilovolts) ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── LOCALITY │Locality │The suburb that the feature is located in. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── STATE │State │QLD, NT, NSW, ACT, VIC, TAS, SA, WA, NT. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── FEATURE_SOURCE │Feature Source │The resource used to locate the feature geographically. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── FEATURE_SOURCE_DATE │Feature Source Date │The date the resource used was published. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── ATTRIBUTE_SOURCE │Attribute Source │Source of attribute information for feature. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── ATTRIBUTE_SOURCE_DATE│Attribute Source Date│The date that the attribute source information was published. ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── SPATIAL_CONFIDENCE │Spatial Confidence │Ranked from High confidence (1) to minimal confidence (5). ─────────────────────┼─────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── LATITUDE │Latitude │Latitude coordinate of the feature location.
