A Farm with History and a Clear Message

Wolfertschwenden

For generations, the farm of Johannes Grimm and his family has been part of the village landscape in Wolfertschwenden. As one of the oldest homesteads in the area, it has long been rooted in agriculture. In the past, it was home to dairy farming, corn, and grain cultivation. Today, the farm is maintained part-time, with boarding livestock and leased agricultural land.

As you arrive at the Grimm farm, a large sign immediately catches your eye:

“There is no lord so high in the land who does not depend on the farmer’s hand.”

– a phrase that couldn't be more fitting.

Just as agriculture has long stood for security of supply, today the same is true for decentralized energy sources. Sustainability, independence, and reliability – these principles are essential in both sectors to build a future-proof foundation for the next generations.

Renewable Energy – A Logical Decision

Fourteen years ago, the family installed a photovoltaic system on their barn roof. The idea was simple: use solar energy directly on site and feed it into the grid. It soon became clear that energy storage was the logical next step – since solar power is generated during the day, but not always consumed at the same time. The ability to store this energy and use it when needed just made sense to him.

Why Battery Storage?

Since May 2024, Johannes has received countless inquiries from battery storage developers. The reason: his land lies directly next to the village’s substation – an ideal location for a large-scale battery storage system. However, many of the inquiries lacked credibility, with unclear concepts and questionable expertise.

“You can quickly tell who just wants to secure land, but has no idea what comes next.”

In September 2024, Johannes came into contact with green flexibility – a connection that began through the mayor of Wolfertschwenden. On-site consultation, solid technical expertise, and a coherent overall concept ultimately tipped the scales in favor of green flexibility.

The planned battery storage project will have a capacity of 10 MW and 25 MWh, aiming not only to strengthen local energy security but also to create long-term economic prospects for his farm and family.

Looking Ahead

The permitting process is currently underway, with construction scheduled to begin in 2025. “I’m excited about the project and proud that we can help contribute to the energy transition.”
