MEAG, the asset manager of Munich Re and ERGO Group, has acquired the Metelen Battery Park, a 92.5 MW / 231 MWh battery energy storage system (BESS) located in North Rhine-Westphalia. Entrix, Germany’s leading provider of multi-market optimization for battery storage systems, will be responsible for the project’s optimization and trading strategy. The fully merchant project is scheduled to go live in the second half of 2025 and will be the largest BESS installation in the Münsterland region and one of the largest in Germany.

Future-Proofed by Intelligent Market Integration

Entrix will manage the battery through its AI-driven trading platform, optimizing the asset across all relevant energy markets—including frequency containment reserve (FCR), automatic frequency restoration reserve (aFRR), as well as day-ahead and intraday wholesale markets. The fully merchant multi-market model enables agile adaptation to market dynamics while delivering attractive returns for MEAG’s investors.

“A fully merchant battery like Metelen is perfectly suited to unlocking the revenue potential of our multi-market strategy. Our close partnership with MEAG enables us to drive renewable energy integration while maximizing economic performance,” says Steffen Schülzchen, CEO of Entrix.

MEAG Expands into Energy Transition Infrastructure

The acquisition of Metelen Battery Park marks MEAG’s first investment in battery storage technology. Originally developed by SMA Altenso, the project will benefit from their continued involvement as EPC and long-term O&M partner.

Battery storage systems play an important role in the energy system. Systems like Metelen make a key contribution to the integration of renewable energies by creating grid stability and making electricity flexibly available when it is needed. The combination of high-performance technology and intelligent, market-oriented optimization by partners such as Entrix makes Metelen an attractive and sustainable investment – with a contribution that extends beyond the location”, Philipp Deisler, Head of Infrastructure Equity Asset Management, MEAG.

Acquired at a ready-to-build stage, the project represents the starting point of further investments by MEAG into national storage infrastructure. With €345 billion in assets under management—€61 billion of which is for private and other institutional investors—MEAG is one of Europe’s leading institutional asset managers.

SMA Altenso Remains Technical Partner

SMA Altenso GmbH, a wholly owned subsidiary of SMA Solar Technology AG, will serve as both EPC contractor and operations & maintenance provider for the battery park. As an international system integrator, Altenso brings extensive experience in the development of large-scale battery storage systems and advanced energy applications.
