🇵🇱 Transformer Industry — Poland

Poland is a fast-transitioning 50 Hz ENTSO-E market, with PSE (PSE S.A.) operating the transmission grid and several DSOs. Its coal-to-renewables transition and grid reinforcement are driving large transformer, GSU and reactor demand, and the country is a strong manufacturing and sourcing hub.
