Electricity-system structure
The page structures electricity-system data by layer so that the condition of generating plants is not conflated with transmission or distribution performance. This supports clearer analysis of operational bottlenecks and rehabilitation needs.
- Generating plants, including nominal, available and operational capacity and actual output where available.
- Transmission networks, substations and 400, 230 and 66 kV lines within the limits of available data.
- Distribution, supply hours, losses, regional interconnections, rehabilitation and expansion projects.
How is asset status classified?
Each asset or project is documented with a clear reference date, distinguishing partially operational, operational, under rehabilitation, suspended and uncertain status. Historical nominal capacity is not evidence that an asset is currently operating.
Official sources are prioritised, followed by implementing entities, technical and international sources, and verified media, with data quality shown explicitly.
