Energiequelle GmbH has successfully commissioned three wind turbines in Schleswig-Holstein in the South of Germany. The Vestas V150 turbines have a hub height of 148 meters and a total installed capacity of 18 MW. In the future, they will generate approximately 47,000 MWh of renewable electricity annually, which is equivalent to the average annual consumption of about 9,100 households.

The turbines were erected on a site designated for wind energy development in the regional planning framework. This provided the necessary planning and regulatory basis for implementing the project.

Following approval in December 2023, the project was awarded a feed-in tariff by the German Federal Network Agency in July 2024. Construction began in October 2024, marking the start of the implementation phase. Commissioning took place from September 7, 2026.

“The commissioning of these three turbines marks an important milestone for us. I am pleased that the energy generated here will contribute to a reliable and sustainable electricity supply in the future,” says Eva Sommer, Team Lead Project Management. “I would also like to extend my sincere thanks to the municipalities of Föhrden-Barl and Weddelbrook for their excellent and trusting cooperation throughout the project.”

Construction activities were temporarily affected by challenging weather conditions. In particular, high groundwater levels during the winter months complicated work on the cable route. These delays ultimately resulted in the wind farm being commissioned later than originally planned.

Protection of Large Birds of Prey and Attractive Citizen Investment Opportunity
To protect large birds and birds of prey, a mowing management concept is being implemented. During harvesting periods, the wind turbines can be temporarily shut down when necessary. In addition, diversion areas have been created to keep the animals away from the immediate vicinity of the turbines.

Energiequelle has also introduced a citizen participation scheme. Local residents were able to invest with a minimum contribution of € 3,000 and will receive a fixed annual return of five percent over a period of four years. This enables the local population to benefit financially from the wind farm while ensuring regional value creation.

The wind farm therefore not only supports the expansion of renewable energy in the region but also strengthens public acceptance of the energy transition.

Energiequelle GmbH has sold its French subsidiary, Energiequelle SAS, to the French company H2air. With this transaction, Energiequelle continues its strategic focus on defined core markets. The sale includes both the employees of the French company and its existing project pipeline.

The French subsidiary has been part of the Energiequelle Group since 2010. Together with the local team, Energiequelle has developed and commissioned more than 27 wind and solar parks with a combined capacity of 266 MW over the past years, making a significant contribution to the expansion of renewable energy in France.

In recent years, the renewable energy sector as a whole has faced challenging market conditions. Energiequelle is currently undergoing a phase of consistent strategic realignment. Against this backdrop, the company decided to transfer its activities in France to an experienced regional player and to focus its own resources on its strategic core regions.

H2air strengthens its regional presence
With H2air, an established French renewable energy developer and operator is taking over Energiequelle’s French subsidiary. The company is pursuing a long-term growth strategy in France and aims to further expand its regional presence through the acquisition.

“I am pleased to announce the successful completion of this transaction with Energiequelle. Thanks to its expertise and longstanding regional presence, Energiequelle SAS has established itself as a key player in the French market. This acquisition fully supports H2air’s strategy to further strengthen its position in renewable energy, particularly in the wind energy sector, in France,” said Roy Mahfouz, Founder and President of H2air.

The existing projects and the expertise of the employees are expected to play an important role in this process. As part of the transaction, all employees of Energiequelle SAS will be transferred to H2air. The transaction includes a wind and solar project pipeline totaling approximately 500 MW, including 60 MW of operational projects and projects already in the pre-construction phase, which will be taken over by H2air.

Throughout the entire process, Energiequelle’s priority was to secure the future of its employees and ensure the continued development of the projects: “With H2air, we have found an experienced and committed partner who meets these requirements. We are therefore pleased that the transaction has been successfully completed and that both the projects and the team are moving into good hands. My special thanks go to all employees of Energiequelle SAS. Through their commitment, expertise, and trusting cooperation, they have played a decisive role in the company’s successful development and in the implementation of numerous projects in France. We wish the entire H2air team every success for the future,” said Michael Raschemann, Managing Director of Energiequelle GmbH.

Energiequelle GmbH continues to advance the expansion of renewable energy in Brandenburg (Germany): with the commissioning of a wind turbine in Danna, the company is expanding the existing wind farm in neighboring Feldheim, the village that Energiequelle made energy self-sufficient 15 years ago. As this project represents an infill expansion of the existing wind farm, no additional land is required; instead, the already designated wind energy area is being utilized more efficiently.

The modern Enercon E-138 EP3 E3 turbine has a hub height of 160 meters and an installed capacity of 4.26 MW. Annual electricity generation is expected to reach approximately 9,000 MWh. This amount of renewable electricity is enough to supply the equivalent of around 2,600 to 2,700 three-person households per year.

Matthias Tamm, Project Manager at Energiequelle GmbH, expressed his appreciation for the constructive cooperation with both the permitting authorities and local landowners and residents: “The planning process proceeded almost seamlessly. Energiequelle’s strong roots in Feldheim clearly contributed to the trust that exists among all project stakeholders.”

With the commissioning of the Danna turbine, Energiequelle is sending a clear signal in support of the efficient expansion and modernization of existing wind energy sites. The project represents an important building block in the sustainable further development of the long-established energy hub of Feldheim.

Energiequelle GmbH has successfully commissioned another wind turbine in the Barnim district of Brandenburg, Germany. With the delivery of the first kilowatt-hour, the company is expanding its existing wind farm with a state-of-the-art Enercon E-138 EP3 E2 turbine, featuring a hub height of 160 meters and an installed capacity of 4.2 megawatts.

The new turbine is located within the Krummensee priority area for wind energy development in the municipality of Werneuchen and complements the existing wind farm, where projects such as Krummensee IV had previously been realised. A site quality factor of nearly 80 percent highlights the favourable wind conditions at the location and provides a solid foundation for reliable long-term electricity generation from renewable energy sources.

However, the path to commissioning was longer than originally anticipated. The environmental permit for the project was granted as early as July 2021. Due to legal proceedings, implementation of the project was significantly delayed. To ensure the continued validity of the permit, an extension notice was issued in July 2024.

Following the resolution of the legal dispute, preparatory construction activities began in September 2024. These included archaeological investigations, the recovery of archaeological artefacts, and the construction of access roads and work areas. With the start of foundation works in March 2025, the actual construction of the wind turbine commenced.

In addition to renewable energy generation, nature conservation also played an important role in the project. As a compensatory measure, a crane habitat was created by rewetting a natural depression in an agricultural field, thereby establishing a water body and adjacent foraging area.

"This project has accompanied us for many years and repeatedly presented us with new challenges. We are therefore all the more pleased that the turbine has now been successfully commissioned. Our sincere thanks go to all colleagues, partners, authorities, and service providers whose commitment and perseverance contributed to the success of this special project," said Vincent Wahrenburg, Project Manager at Energiequelle GmbH.

With its successful commissioning, the Krummensee turbine will make a further contribution to climate-friendly electricity generation in Brandenburg and support the expansion of renewable energy in the region. The positive development of the site is set to continue in the coming years with an additional wind turbine already planned.

Energiequelle GmbH has begun construction of the Lüben Wind Farm in the district of Gifhorn in Lower Saxony (Germany). The project consists of five state-of-the-art Enercon E‑138 turbines with a hub height of 160 meters. Each turbine has a capacity of 4.26 megawatts, and together they will generate around 77 million kilowatt-hours of electricity per year. This is enough to supply approximately 22,000 households with CO₂-free electricity – an important contribution to the regional energy transition around the municipality of Wittingen.

Approval for the wind farm was granted in December 2024, followed by an award from the Federal Network Agency in the February tender for onshore wind energy. After completion of all preparations, construction of the access roads is now beginning. Commissioning is scheduled for the second and third quarters of 2027.

Lüben is already the second Energiequelle wind farm within a year in the municipality of Wittingen. The Teschendorf Wind Farm, located not far from Lüben, was commissioned last autumn.

Financial Participation for the Region
To involve the municipality and local residents in the project, Energiequelle is implementing several participation models. As already successfully introduced in Teschendorf, residents of Lüben will also be offered an annual electricity bonus of 200 euros, enabling them to benefit directly from the wind farm.

In addition, Energiequelle will provide the town of Wittingen with 0.2 cents per kilowatt-hour generated, in accordance with Section 6 of the German Renewable Energy Sources Act (EEG). This corresponds to annual revenue of 154,000 euros. The new Lower Saxony Participation Act adds a further 0.1 cents per kilowatt-hour – generating an additional 77,000 euros annually.

Finally, landowners have agreed to contribute part of their lease income to a newly established association in order to support meaningful and beneficial local investments. As a result, the wind farm will not only contribute to sustainable energy supply but will also strengthen the local community.

Tina Hermerding, project leader at Energiequelle, is delighted by the willingness of landowners to contribute a share of their income for the benefit of the community, noting that this is far from a given. She is also pleased about the successful start of construction, as the project’s development phase was long and demanding: “The regional planning process lasted more than ten years and required a great deal of patience. I am all the happier that we can now move into the implementation phase. My thanks go to everyone involved for their perseverance and constructive cooperation.”

The Lüben Wind Farm marks another important milestone for the regional energy transition while also setting an example for successful citizen participation.

Energiequelle GmbH has successfully commissioned a new wind farm in Teschendorf. The project, planned and constructed in the district of Gifhorn, comprises five state-of-the-art Enercon E138 turbines. With a hub height of 131 meters and an output of 4.2 megawatts each, the turbines will generate around 60 Million Kilowatt hours of electricity per year. This is enough to supply approximately 17,000 households with CO₂-free electricity – a significant contribution to the energy transition in Lower Saxony.

The path to realization was long: regional planning alone took ten years, followed by a two-year zoning procedure. Only in June 2024, after a total of twelve years of planning, construction began. The construction phase went smoothly and all turbines were successfully connected to the grid as scheduled in October 2025.

Financial Participation for the Region
The wind farm does not only contribute to sustainable energy supply, it also strengthens the local community. A total of around € 3 million will flow to the city of Wittingen and the surrounding villages.

This is based on Section 6 of the Renewable Energy Sources Act (EEG), which allows project developers to pay 0.2 cents per generated Kilowatt Hour to the municipalities. For Wittingen, this means annual revenues of around € 120,000 euros. In addition, the Energiequelle Foundation provides € 300,000 for charitable purposes – equivalent to € 15,000 per year. Over a lifespan of 20 years, the city of Wittingen and its districts Teschendorf, Küstorf, Schneflingen, and Mahnburg will receive around € 2,7 million.

Residents of the mentioned districts can also participate directly: after successful registration every household receives an annual power bonus of € 200, guaranteed for ten years. With around 180 households, this amounts to another € 360,000.

For project manager Tina Hermerding financial participation is a key factor for the successful implementation of wind energy projects: “In order to create acceptance for projects in the field of renewable energies, it is important to involve people and the community financially. Through both the EEG and the Energiequelle Foundation, as well as the power bonus, we have established legally sound ways to do this.”

The Teschendorf wind farm is a prime example of successful acceptance work: alongside transparent information policies, financial participation of local residents is a central tool for shaping the energy transition together.
