E.ON SE, through its subsidiary E.ON Energy Infrastructure Solutions $(EIS)$, has signed a memorandum of understanding with SEC Zgorzelec and Stadtwerke Görlitz to establish a joint project company for the operation of a cross-border district heating network between Poland and Germany. The initiative, known as "United Heat," aims to deliver climate-neutral and secure heating to the cities of Zgorzelec and Görlitz by 2030, with an expected annual CO₂ savings of up to 50,000 tons. The joint venture will oversee both the construction and future operation of a 12-kilometer-long connection, including a 3.8-kilometer section crossing the border. The total investment volume is projected to reach up to 195 million euros, pending approval from relevant competition authorities. This EU-supported project is positioned as a model for future cross-border energy collaborations in Europe.
