A cutting-edge energy system has been implemented at the Bad Salzungen power plant site, demonstrating how battery storage is used today: as an integral part of a smart, intelligently controlled energy system. In collaboration with TEAG Solar and WAGO, a pilot project was launched that not only opens up a new business segment but also serves as a blueprint for future storage solutions.
TESVOLT was responsible for the development and integration of the battery storage system and the central management system—thereby laying the foundation for a system that not only stores energy but also actively controls it and makes it economically usable.
Growing Demands on Energy Storage and System Integration
With the increasing expansion of renewable energy, the need for flexible storage solutions that can shift energy over time and utilize it to benefit the grid is rising. For TEAG Solar, this meant establishing a new business segment in the field of battery storage—with the goal of creating not just a technical solution, but a sustainable overall system.
The focus was on a solution that not only meets today’s requirements but can also respond flexibly to future developments in the energy market.
Complex system integration across organizational boundaries
The project posed significant challenges in terms of technical and organizational implementation. Different systems and responsibilities had to be seamlessly integrated:
Added to this were the typical challenges of a pilot project—from approval processes and construction requirements to the development of a scalable system architecture.
The decisive factor for success was therefore the close collaboration of all parties involved: TEAG Solar as the project initiator and operator, WAGO as a specialist in control technology, and TESVOLT as the integrator of the battery system and the overarching system logic.
A holistic energy system with intelligent control
Together, an integrated energy system was implemented in which generation, storage, the grid, and marketing work seamlessly together.
TESVOLT developed and integrated:
The system enables:
A key component is the management system, which processes operational data, integrates market signals, and controls the facility in real time. This allows energy to be actively managed—rather than simply stored.
WAGO’s control technology ensures reliable connection to the grid and compliance with all regulatory requirements.
A Blueprint for Future Energy Systems
Since its commissioning, the project has demonstrated how modern battery storage systems function as part of a networked energy system. The storage system is already integrated into the market and enables flexible energy utilization depending on market conditions.
For TEAG Solar, the project marks a successful entry into a new business segment. At the same time, it serves as a scalable model for future projects—such as at other grid locations or in combination with renewable generation facilities.
For TESVOLT, too, the project is an important milestone: It demonstrates how the combination of storage technology, intelligent energy management, and collaborative implementation creates solutions that meet the demands of a changing energy market.
Partnership as a Key to Success
The project in Bad Salzungen makes it clear: The energy transition requires not only high-performance technologies, but above all strong partnerships.
Through close collaboration between TEAG Solar, TESVOLT, and WAGO, a system has been developed that goes far beyond a traditional storage solution—and can serve as a new standard for integrated, cost-effective energy storage.
