Uniper Finalizes Sale of Ruhr District Heating Facility
Uniper SE announced on Monday that it has finalized the sale of Uniper Waerme GmbH, a district heating network serving over 14,400 customers in Germany's Ruhr region, to Steag Iqony Group’s Iqony Fernwaerme GmbH. This divestment is part of Uniper's compliance with competition regulations set by the European Commission during the approval of its government bailout in late 2022. Uniper Waerme operates a network exceeding 750 kilometers (466.03 miles) and specializes in efficiently utilizing heat from electricity production in combined heat and power plants, as well as employing various eco-friendly heat generation alternatives, such as mine gas, waste heat from industrial processes, and heat from electric boilers and smaller decentralized CHP plants.
In an earlier announcement on August 4, Waerme's managing director, Nikola Feldmann, expressed satisfaction in finding a buyer like Steag Iqony Group to maintain their operational direction and provide stable employment for approximately 130 employees. The companies did not disclose the sale price.
Additionally, Uniper revealed it has agreed to sell the Datteln IV coal-fired power plant in North Rhine-Westphalia to ResInvest Group AS as part of its bailout compliance. Commissioned in 2020, the Datteln plant has a net capacity of 1,052 megawatts (MW) and supplies electricity and district heating to households, as well as traction power to Deutsche Bahn. More than 100 employees at the site will transfer to ResInvest.
This transaction is awaiting regulatory approval. In July, Uniper sold its 18.26 percent stake in AS Latvijas Gaze, which operates in natural gas trading in the Baltics, to co-venturer Energy Investments SIA. Latvijas Gaze is the largest gas supplier in Latvia's household sector.
In February, Uniper completed the sale of its North American power portfolio, covering various power purchase and sale contracts across multiple markets, excluding its gas and hydrogen-related assets. In January, Uniper sold its natural gas-fired power plant in Gonyu, Hungary, to the local subsidiary of France's Veolia SA.
As part of the bailout conditions, Uniper also completed the sale of its marine fuel trading business in the UAE and its 20 percent indirect stake in the BBL gas pipeline between the Netherlands and the UK. Remaining assets set for divestment by 2026, as agreed with the European Commission, include an 84 percent stake in Unipro in Russia, a 20 percent stake in the OPAL pipeline, and Uniper’s international helium business.
