Energiekontor and illwerke vkw continue successful cooperation and conclude purchase agreements for two German wind park projects with around 93 megawatts

Bremen/Bregenz, 21 January 2026 – Energiekontor AG (“Energiekontor”), a leading German project developer and operator of wind and solar parks based in Bremen and listed in the General Standard, and Austria's illwerke vkw AG (“illwerke vkw”) concluded contracts for the turnkey sale of two German wind parks with a total nominal power of around 93 megawatts before the start of the new year. Energiekontor thus ended the 2025 financial year with seven successful sales, as announced on 29 December 2025. With this transaction illwerke vkw is expanding its own Völkersen wind park, which Energiekontor sold to illwerke vkw in 2021, to around 104 megawatts in the future.

The purchase agreements are for the Haberloh and Heidkrug onshore wind park projects in the Verden district of Lower Saxony, Germany, with a total nominal power of around 93 megawatts. The buyer of the wind parks is illwerke vkw AG, an energy supply company based in Bregenz, Austria, which is actively pursuing its vision of a secure, affordable and renewable energy supply through numerous projects. To this end, the company is continuously expanding its own power generation capacities and, at the same time, exploiting synergies with its own pumped storage power plants. In 2021, illwerke vkw acquired the Völkersen wind park with a nominal capacity of around eleven megawatts from Energiekontor. Völkersen began operating in 2023. Since then, Energiekontor has been responsible for the technical and commercial management of the park. The additional parks now being sold are located in the immediate vicinity of the Völkersen wind park, meaning that illwerke vkw will expand this site to a total of around 104 megawatts once the two new parks are commissioned.

The Haberloh and Heidkrug wind parks will have a nominal power of approximately 79 and 14 megawatts respectively. A total of 13 Vestas V162-7.2 wind turbines are planned across the two sites. The individual turbines will have a hub height of approximately 169 metres and a rotor diameter of 162 metres. The average expected annual yield of both wind parks from the first full year of operation will be around 220 gigawatt hours – enough to supply more than 66,000 average households with renewable electricity and save around 160,000 tonnes of CO₂ per year. The projects benefit from an EEG feed-in tariff, which was awarded by the Federal Network Agency as part of the May 2025 tender.

“The conclusion of the purchase agreements for the two wind parks marks a successful operational end to the 2025 financial year, with a total of seven sales and 14 financial closes. The turnkey handover of the Haberloh and Heidkrug wind parks, which is planned for the end of 2027, will create another reliable earnings base for the coming years, in addition to our own electricity generation. We are also very pleased to be continuing our established cooperation with illwerke vkw and to be jointly developing the Völkersen wind park site – a strong sign of the quality of our projects and the trust that long-term partners have in Energiekontor,” says Peter Szabo, CEO of Energiekontor AG.

“By acquiring the Haberloh and Heidkrug wind parks, we are continuing to move forward on our path towards a renewable energy future. Increasing our wind energy generation capacity is a key part of our corporate strategy”, says Gerd Wegeler, member of the illwerke vkw Management Board. “We are delighted to be taking another important step forward together with Energiekontor and expanding our portfolio strategically. This successful cooperation demonstrates how valuable strong partnerships are in achieving our ambitious expansion goals: by 2040, we want to increase our electricity production from wind power and photovoltaics to 1,000 gigawatt hours.”
