Project developer MaxSolar and Leipzig-based flexibility trader Energy2market (e2m) have signed a seven-year hybrid power purchase agreement covering the joint marketing of a 45 MW solar park and a 20 MW battery storage facility with a capacity of 40 MWh in Waren (Müritz), Mecklenburg-Western Pomerania.

The agreement, announced on 8 October 2026, is the first hybrid PPA in Germany that safeguards the remuneration of a battery storage system via a floor mechanism. Under the structure, the operator receives a share of the optimisation revenues while remaining protected by a contractually agreed minimum remuneration.

A landmark contract for co-location projects

The solar park began operations in the summer of 2026, with the battery storage facility set to follow in September 2027. The two assets are designed as a co-location project and share a common grid connection via their own substation.

Fourth co-location, fourth marketing concept

For MaxSolar, the Waren project marks another step in its co-location strategy.

"Following Gemmingen, Friedrichshof, and Darstadt, we are launching our fourth co-location in Waren, featuring our fourth marketing concept," said Moritz Kimmich, PPA Origination Manager at MaxSolar.

"With Energy2market, we are partnering with a very strong player in the field of flexibility trading. The agreed floor structure combines long-term predictability with optimal management of the battery storage system, thereby creating benefits for both contracting parties."

Filip Markert, Originator at Energy2market, described the deal as breaking new ground.

"In recent years, we have already been able to unlock attractive revenue potential by optimising green electricity storage systems co-located with PV; now, for the first time, we are combining this with long-term revenue protection," he said. "The floor structure creates predictable cash flows without the operator having to surrender all the optimisation revenues from their storage system."

Intelligently linking generation, storage, and marketing

The combination of photovoltaics and battery storage at a shared grid connection point offers additional flexibility in the marketing of renewable energy. Because the battery storage system is not tied to the time at which solar energy is generated, it can respond specifically to market and price signals.

In multi-market optimisation, the storage system is marketed in whichever market segment, day-ahead, intraday, or balancing energy, offers the highest revenues.

Under the seven-year hybrid PPA, MaxSolar gains long-term revenue security while e2m handles market-optimised marketing and management of the co-location project.

Predictable cash flows as a building block for an IPP portfolio

Christoph Strasser, Managing Director of MaxSolar, framed the deal within the company's broader strategy. "A NextGen IPP requires not only a diversified portfolio of plants but also innovative and varied marketing models," he said.

"With structures such as those used in the Waren project, MaxSolar generates predictable cash flows, strengthens the financial viability of the projects and, at the same time, retains the opportunity to tap into additional revenue potential in the energy markets. For us, this combination is a key building block for a resilient and growing IPP portfolio."

EDF Group backing and a blueprint for future projects

Energy2market, which has been part of the EDF Group since 2019, sees the contract as a model for future collaborations.

"The energy transition requires not only more renewable generation and storage but also marketing models that intelligently combine the two and ensure their long-term viability," said Hannes Behacker, Managing Director of Energy2market.

"With our experience in flexibility trading, our own financial strength, and the EDF Group behind us, we can not only structure innovative contract models but also secure them for the long term. Together, with this project, we are creating a blueprint for the next generation of co-location projects."

MaxSolar and e2m intend to continue their collaboration in the long term. The experience gained from the Waren project will be incorporated into the development and marketing of further commercially viable co-location and storage projects.
