IEA Electricity Grids and Secure Energy Transitions (grid line length)

International Energy Agency

Power-grid line length (transmission + distribution, km) by region - 2021 installed + 2030 Stated Policies Scenario; the grid-copper demand-side DeploymentRecord lane on the grid_line_length_km basis (sector ELECTRICITY_TD)

Quirks

Committed curated CSV at data/iea_grids_2023/ (not data/raw) - 9 IEA regions; the World row is a checksum the parser SKIPS (the regions sum to it, so emitting it would double-count)
Grid copper scales with LINE LENGTH (km), not generation MW - a dedicated grid_line_length_km basis; intensity 1500 kg Cu/km (blended T&D, MEDIUM, band 1000-3000)
Classified STOCK in the demand seam: ~116 Mt embodied grid copper, sized against reserves, never summed with the ICSG annual end-use split
