A curated list of electrical grid maps, datasets, and resources for (almost) every country in the world.
Two views over one interactive map - searchable by country, state or province, with one-click CSV exports.
- Data coverage - every dataset listed below, plotted by country, state and province and coloured by type.
- Global Transmission Length Index - how many kilometres of high-voltage line each country actually has.
Our own country-by-country research into the size of the world's transmission grid: 7.65 million km of line at 50 kV and above across 131 countries, with per-voltage breakdowns, sources and reporting years. Rank countries by total length, by 220 kV+ backbone, or by line-km per 1,000 km² of area.
