Innovative energy concept: High-Power Charging & energy management in one system

Best case studies for the retail industry

holistic and economical energy concept for the retail sector

Numbat is more than a classic High-Power Charging station. It is a combination of HPC and battery storage. With the battery storage and the innovative technology behind Numbat, the diverse and complex challenges currently facing the retail sector can be solved.

Retail - "gas station" of the future?

According to a survey of consumers conducted by EHI and UScale, most drivers (82.4%) use their cars for shopping. Retailers can therefore score points with EV drivers by offering ultra-fast charging in their parking areas. EV drivers save themselves the extra trip to the charging station. Retailers are thus supporting the energy transition and at the same time fulfilling the desire of more and more customers to charge quickly while shopping.

Best Practice Examples:
Feneberg and Tegut... gute Lebensmittel

To be able to solve the current challenges in the field of renewable energies and e-mobility holistically and economically, an overall solution is needed that combines these topics.

The grocery chains Feneberg and tegut… gute Lebensmittel have also recognized this and entered into a cooperation with Numbat. The fast charging station with integrated battery storage (“Numbat”) corresponds to the ideas of a sustainable solution for customers of the supermarket.

The following points were particularly important to the food retailers:

  • Possibility of storing and using self-generated PV power as well as versatile energy management
  • Climate-neutral fast charging solution
  • Grid connection is irrelevant
  • Economic business model
  • No effort for operation, billing, maintenance, etc.
  • Fast implementation of fast charging stations for customers at as many locations as possible (no “cherry picking”)
  • Integration of the charging infrastructure into loyalty programs (customer retention)

In the end, it has to be a win-win situation where the customer is the focus. We analyzed numerous providers of charging stations and also combinations with battery storage, but Numbat's model convinced us immediately, as there is no comparable provider with such a business model and product on the market."

Managing Director Feneberg

The large providers of fast charging stations only supply places that are optimally located – that is, where as many e-cars as possible drive by. Rural areas are often forgotten in the process. In addition, they usually require connection to the medium-voltage grid, which is associated with high costs, construction measures, and very long waiting times for transformer stations. Numbat avoids the so-called “cherry-picking” and can equip all places, for example also parking lots in rural areas. The integrated battery storage leads to an uncomplicated connection to the power grid. Together with Feneberg, nearly 50 locations were selected. The first systems went into operation in January 2023. At almost all tegut… locations will have up to 1000 charging points in 2023.

When tegut... was founded 75 years ago, we made it our mission to act responsibly with good food. This "responsible action" does not stop for us when a customer leaves the store. We implement it throughout the company. On the one hand, an environmentally friendly fast-charging service is of course an additional service offering for our customers, but on the other hand it is first and foremost a major investment in clean mobility. In addition, the battery storage options enable us to implement the relevant energy topics in our company in a targeted manner."

and Real Estate tegut…


Construction and installation of the first Numbats at the respective locations began in 2022, with additional locations to follow. The grocery retailers will be able to feed the battery storage integrated in the fast charging station with self-generated electricity from in-house PV systems and, through various applications of Numbat in the energy management area, balance out high load peaks and thereby reduce costs. This will provide the most sustainable fast charging currently available at the relevant locations.

The offer of fast charging in the supermarket parking lot is a basic need for customers. In the future, the short charging process can be ideally integrated into the customer’s daily routine and the trip to the gas station or the journey to a charging station not on the route is no longer necessary. 

tegut… and Feneberg are thus setting themselves apart from other grocery retailers and taking on a pioneering role in the retail sector. With the Feneberg cooperation, Numbat implemented the pilot project of a nationwide fast charging network in the Allgäu region and was thus also able to increase the visibility of its own company on the market. This is also reflected in the following cooperation with tegut….
