A Spatial Dataset of China’s Power Transmission Network Across 2015 2020 and 2025

This dataset provides multi-temporal geospatial vector data of China’s power transmission network, including Transmission lines, Substations and Power Plants for 2015, 2020 and 2025. All vector data are cleaned, topologically checked, and standardized to a uniform coordinate system (e.g., WGS84, EPSG:4326) for direct use in GIS software (ArcGIS, QGIS, etc.).The data were collected and processed from legitimate sources. This dataset can be used for power grid planning, energy system simulation, spatial analysis, disaster risk assessment, and low-carbon energy transition research, providing reliable data support for related scientific studies.
