In Grevesmühlen, Mecklenburg-Vorpommern, energy specialists Fenecon and The Mobility House Energy are constructing a high-capacity large-scale battery storage system with a capacity of 48 MWh, mirroring a sister project with 8 MWh in North Rhine-Westphalia. Site preparations are nearly complete.
Once the local substation, being developed by E.DIS Netz GmbH, is completed, the battery storage system is scheduled to become operational in the second half of 2025. A distinctive feature of this project is the exclusive use of new but obsolete electric vehicle (EV) drive batteries.
Fenecon is developing and producing modular storage containers that efficiently and standardizedly integrate obsolete EV batteries from various manufacturers into stationary large-scale storage systems.
The Mobility House Energy leverages its extensive expertise and intelligent marketing algorithms to ensure minimal battery degradation and maximum economic efficiency.
Optimized operation extends battery life
The Mobility House Energy brings its extensive experience in the intelligent marketing of vehicle batteries to the project. Utilizing proprietary algorithms, the battery storage systems are operated in a manner that is both grid-supportive and particularly gentle on the batteries. This approach reduces battery aging and maximizes their lifespan -an important contribution to a stable, sustainable, and cost-effective renewable energy system.
"It's astonishing to consider: In Germany, more brand-new, high-quality, yet obsolete EV batteries are currently being shredded each year than are installed in large-scale storage systems—which, in turn, are usually newly produced in China. Our mission, along with that of our dedicated partners and customers, is to utilize these high-quality batteries within 'Made-in-Germany' stationary storage systems in the energy market, capitalizing on their advantages in terms of round-trip efficiency, thermal management, and consequently lower operating costs."

FENECON GmbH
"Battery storage systems are an indispensable component of the future electricity market. By utilizing vehicle batteries before, during, or after their use in EVs, we create added value for our energy system and simultaneously make electromobility more affordable."

Long-term partnership with a future
Fenecon will be responsible for the operation and maintenance of the storage system. This project builds upon the successful partnership between the two companies and demonstrates how technological innovation, sustainable resource utilization, and economic solutions for the energy transition can go hand in hand.
