With eight facilities and a total capacity of 44.7 MW, Seewald is one of the largest wind projects in the region – a significant step for the Energy transition 2.0 in the southwest and a clear signal for a sustainable energy infrastructure.

8 Wind turbines (WTs) are being constructed in Seewald.
44.7 MW The total capacity of the Seewald wind park is managed annually.
28,500 Seewald thus supplies an average of households annually.
75,600 Tons of CO₂ are saved annually on average.

Our approach: Energy transition 2.0

EEF stands for the Energy transition 2.0 – a new generation of sustainable energy projects. Our solutions go beyond mere electricity production: they are decentralized, locally effective, and digitally connected. Thus, we create real added value – ecologically, economically, and socially.

Wind power with foresight

In the heart of the Black Forest, one of the largest wind projects in Baden-Wuerttemberg is emerging – a pioneering step for the regional expansion of renewable energies. In the district of Besenfeld, Freudenstadt, EEF demonstrates how Energy transition 2.0 works: decentralized, technologically foresighted, and in close collaboration with the region. In a state with little wind infrastructure but a high industrial energy demand, the Seewald wind park complements photovoltaics – especially during the dark winter months. A potential (energy/battery) storage solution will further enhance grid stability and security of supply. Seewald clearly shows that the energy transition is not only feasible in the north, but also requires pioneer projects in rural areas – in the forest, locally, in dialogue with the region.

Show responsibility. Create added value. Act together.

EEF develops projects like Seewald always in dialogue with the local communities. Our goal: We create not only clean electricity but also social and ecological added value.

The surrounding communities directly benefit from the Seewald wind park – through participation under §6 EEG with 0.2 cents per kilowatt-hour fed into the grid. Moreover, we support local clubs, organizations, and initiatives throughout the operational lifetime of the project.

At the same time, we implement targeted ecological measures that strengthen nature and biodiversity. Thus, a project emerges in Seewald that unites technological innovation, regional value creation, and responsibility for the environment and society.

Compensatory and replacement measures

  • New Habitats

    New habitats are created in the forest through artificial quarters for bats and nesting aids for cavity-nesting birds. This strengthens species that rely on natural structures but often lose refuges due to forest restructuring or timber harvesting.

  • Initial Afforestation

    New trees are planted on suitable land to expand and stabilize natural spaces. This not only grows new forests but also contributes to climate protection and recreation for future generations.

  • Forest Conversion

    Coniferous forests distant from natural conditions are gradually transformed into climate-resilient mixed deciduous forests – such as lime-beech or black alder-ash forests. Thus, diverse ecosystems are created that better withstand heat and drought and promote biodiversity.

Transparency

creates trust

For us, Energy transition 2.0 means making development tangible. We show the milestones that shape a project, where we stand, and how it progresses – openly and collaboratively. Seewald represents progress in the southwest. From approval through construction to the initial power feed-in – here we document the key steps.

Approval according to BImSchG and EEG surcharge

Completed

In April 2023, the Seewald wind farm received the BImSchG approval for eight wind turbines. The application was submitted by Altus as the original developer. At the beginning of 2025, the amendment approval followed for the switch to Nordex plant technology – for more efficiency and future viability.

Access roads and crane pads

Completed

In the first quarter of 2025, work will begin on access roads and crane pads. Existing forest paths will be utilized and specifically upgraded to ensure access for heavy transport. After the completion of the facilities, the paths will be downsized and partially dismantled, while maintaining permanent accessibility for emergency vehicles.

The Base

Foundation construction

Completed

Starting May 2025, the foundations will be constructed by Max Bögl. They will provide a stable base for towers over 200 meters high and represent the transition from planning to construction phase.

Project acquisition

Completed

In September 2025, EEF will take over the Seewald wind park from KMW AG, the parent company of the previous project developer ALTUS renewables GmbH. ALTUS has successfully developed the project until the handover and continues to accompany the construction as a close partner. With the acquisition, EEF expands its portfolio to include a project of high regional and ecological significance.

To the press release

Facility construction

Completed

Starting in October 2025, the first visible steps begin: delivery and assembly of the concrete tower sections. In January 2026, the major components follow – steel tubular towers, nacelles, and rotor blades. From February 2026, the installations will be constructed.

Delivery of transformer station

Cable construction and grid connection

Under construction

In parallel, electrical connections are being prepared. Cable routes connect the facilities to the new Seewald substation, creating a strong network node that not only enables power injection but also strengthens regional infrastructure in the long term.

Park Festival

Planned

In 2026, the completion of the construction phase will be celebrated with a park festival – a moment to visibly promote the energy transition in the region and together with citizens and partners, commemorate a milestone.

Completion

Planned

Starting in August 2026, the commissioning begins. Each unit will be connected to the grid until the entire park is operational. With each step, the regional security of supply with renewable energies increases.

Operational phase

Planned

With a total capacity of 44.7 MW, Seewald is one of the largest wind parks in Baden-Württemberg. For decades, it provides renewable electricity, strengthens regional infrastructure, and demonstrates how Energy transition 2.0 takes shape in rural areas.

Technologies that set standards

The Seewald wind farm utilizes the latest turbines from the Nordex Delta4000 series. This generation of turbines is specifically developed for regions with medium wind speeds, making it ideal for conditions in the Black Forest. With a hub height of 164 meters, the rotor blades reliably reach the higher, windier air layers above the forest.

Types of turbines used:

7x Nordex N149 / 5.7 MW / Hub height 164 m

1x Nordex N133 / 4.8 MW / Hub height 164 m

With a hub height of 164 meters, the turbines reliably utilize the stronger winds above the tree tops. The selected type combination offers high energy yield with economical operation and good integration at the site.

  • High efficiency at medium wind speeds

    The rotor blades with large diameters are designed for optimal performance in regions with less consistent winds – a clear advantage for Baden-Württemberg.

  • Noise-reduced design

    With optimized blade geometry and pitch control, the turbines operate more quietly than comparable models. This makes them particularly suitable for use in forested areas.

  • Digital control systems

    Modern monitoring technology ensures predictable maintenance, high availability, and efficient operation throughout the entire life cycle.

  • Future-proof series quality

    The Delta4000 series is proven, advanced, and modular – ideal for long-lasting operation and easy spare parts supply.

For EEF, dismantling is not just a mandatory program, but part of our commitment to genuine sustainability. A guarantee ensures the complete dismantling of the Seewald wind farm. Facilities are recycled according to the circular economy act, lands are recultivated, and replanted with site-appropriate mixed tree species. Especially in the forest, our principle is: We only intervene if we return at least as much nature as we use at the end. Dismantling for EEF is not a conclusion - but proof that ecological responsibility encompasses the entire life cycle.

Perspectives of our Companions

"It's a special feeling to take over one of the largest wind projects in Baden-Württemberg at this stage. Soon, the first rotors will turn in the Northern Black Forest - in a region where wind energy has been long neglected. That we continue to rely on the local expertise of Altus in construction management and work in partnership with the local people, embeds the project deeply in the region. This is exactly how the Energy transition 2.0 succeeds: together, responsibly, and rooted in the land."

Our Team: The Minds Behind the Project

You have questions? We have the answers.

In sensitive areas such as roads, forests or bodies of water, the horizontal directional drilling method is used - a trenchless and particularly environmentally friendly method.

First, two excavation pits are created: a starting pit and a target pit. From the start pit, a steerable drilling head works its way in a gentle arc under the respective obstacle. Its position is continuously monitored. A bentonite drilling suspension - a special mixture of clay and water - is pumped into the drill channel via the drill rods. It flushes the loosened soil through the channel back to the starting pit and stabilizes the borehole at the same time.

After the so-called pilot bore, the drill head is removed and a widening bulb is attached, which gradually enlarges the channel. Only when the bore channel is sufficiently dimensioned are the empty pipes pulled in. These are later used to pull in the medium-voltage cables and fiber optic cables.

The drilling slurry forms a stable casing around the pipes. Finally, it is disposed of professionally and the excavation pits are backfilled.

The electricity generated at the Beckum wind farm is fed into the public grid. If you would like to use green electricity as a resident, you can choose a certified green electricity tariff from your energy supplier. Some providers even guarantee that the electricity comes directly from regional wind farms. In this way, you can actively support the local energy transition - even without your own solar power plant.
