🇳🇱 Transformer Industry — Netherlands

The Netherlands operates a dense 50 Hz ENTSO-E grid under TenneT (transmission) and regional DSOs, with strong offshore-wind, data-centre and electrification demand. Its transformer market is driven by offshore-wind export, grid reinforcement and a major import-reliance story.
