DATA SOURCES AND METHODOLOGY

All GridReadiness data is derived from: direct manufacturer procurement contacts; RTE public documentation and field verification; government programme announcements (DGE, Choose France, CRE); cross-referencing BASIAS, Cartofriches and RTE network maps. Full methodology: /methodology.

Data is updated monthly. Transformer lead times represent standard HV power transformers (40–200 MVA) and are subject to change. GridReadiness makes no warranty on lead times for specific procurement — direct manufacturer engagement is required for confirmed delivery windows.
