🇬🇧 Transformer Industry — United Kingdom
The UK is a mature 50 Hz, ENTSO-E-synchronised market with a strong engineering heritage, an offshore-wind and interconnector-driven build-out, and a $multi-billion transmission upgrade programme. Its grid operator (National Grid/ESO) and DSOs buy power, distribution and reactor transformers, and offshore wind drives high-value converter and GSU demand.
