🇫🇷 Transformer Industry — France

France operates a high-voltage 50 Hz ENTSO-E grid under RTE (transmission) and Enedis (distribution), with a nuclear-heavy generation mix and a growing renewables build-out. Its transformer market is driven by grid renewal, nuclear and renewable connection, and it hosts major OEM/component engineering.
