Following the successful commissioning of the PV system in summer 2025, Thermal Management Solutions DE Oberboihingen GmbH is taking the next consistent step on its transformation path: Together with CUBE CONCEPTS, the company is now planning the implementation of an industrial Large battery storage (BESS) in the Contracting model. The goal is to further optimize the site’s energy supply, increase the self-consumption rate, and ensure long-term economic viability of carbon neutrality.
From PV to BESS – the next stage for the energy transition
With the roof-mounted PV system installed in August 2025, the company has already reached a significant milestone. It has been supplying Green electricity for thermal management solutions, strengthens self-sufficiency and at the same time forms the technical basis for intelligent energy system integration.
Even during the initial project presentation, Managing Director Holger Kiebel announced that battery storage would be the logical next step to further increase energy efficiency and specifically manage peak loads. This very step is now being concretely prepared.
Impulse through Expert Webinars: Decision for BESS Concept
The impetus for the detailed project planning was provided by the Webinars from CUBE CONCEPTS on the topic of industrial battery storage systems. Participants Dieter Hehl and Albrecht Manz used the events to analyze technological, economic, and regulatory aspects of modern storage solutions.
The result was clear: a battery storage system can not only make PV surpluses usable in an efficient way, but also unlock additional economic potential – for example, through peak load shaving, grid fee optimization, or, in the future, participation in flexibility markets.
The Contracting Model as a Strategic Advantage
The planned implementation will follow the proven Contracting approach. This model makes it possible to integrate a BESS, including an EMS, without any upfront investment costs, while also benefiting from predictable electricity costs and professional operation. For TMS, this means:
- no capital commitment
- maximum planning certainty
- Reduction in electricity costs
- immediate CO₂ reduction effect
- Technological future-proofing
Step 3 on the path to climate-neutral production
The battery storage system represents the third building block of a clearly structured sustainability strategy at Thermal Management Solutions DE Oberboihingen GmbH. After initial implementation of efficiency and optimization measures, as well as compensation projects in operations, followed by the in-house generation of electricity through a photovoltaic system, the energy system is now being flexibly expanded through the use of a storage system.
This is making the Oberboihingen site an increasingly prominent example of industrial decarbonization in practice. As a manufacturer of high-quality thermostat and temperature control technology under the WAHLER brand, the company combines technological precision with sustainable action – while simultaneously strengthening its competitiveness in a changing energy market.
Transformation consistently thought through
With the planned BESS integration, Thermal Management Solutions is consistently continuing its course: moving from individual efficiency measures towards a holistic energy system. The project exemplifies how industrial companies can actively shape transformation – economically viable, technologically sound, and strategically long-term.
