Suena Energy Secures €8M to Automate Renewable Storage Trading

The energy market is rapidly evolving as renewable sources become increasingly significant, yet managing energy storage efficiently alongside intermittent power generation remains a challenge. Hamburg-based Suena Energy addresses this with its AI-powered 'Energy Trading Autopilot,' a software platform utilizing advanced algorithms and real-time forecasting to automate trading decisions across multiple power and ancillary service markets.

Today, Suena Energy closed an €8 million Series A funding round led by Dutch energy company Eneco and its investment arm, Eneco Ventures. The round also included participation from impact venture capital firm 4impact capital, alongside ongoing support from investors InnoEnergy, J.O.S.S., Santander, and Energie 360°.

This funding will accelerate Suena's international expansion and sharpen its focus on co-located battery storage projects, where renewable assets like solar and wind are paired directly with storage, unlocking operational synergies and fresh revenue opportunities.

Founded by Dr. Lennard Wilkening along with co-founders Miguel Wesselmann and Tom Witter, Suena was created to unlock the full flexibility potential of battery storage integrated with renewables. Their mission is to make renewable energy not just scalable but more profitable and reliable, driving the transition toward a decentralized and decarbonized power system.

Suena’s technology suite supports a broad range of applications, from standalone storage to co-located solar-plus-storage and wind-plus-storage projects, as well as direct marketing of renewables and portfolio optimization, serving utilities, developers, and energy traders with a comprehensive, market-leading platform.

In a competitive space that includes companies like Flexitricity, AutoGrid, and Greensmith Energy (now part of Wärtsilä), Suena stands out by offering extensive market coverage and a highly modular software that adapts readily to varying regulations and project conditions.

Its emphasis on co-located assets, one of the fastest-growing segments in the energy transition, gives it a unique advantage in delivering operational efficiencies and unlocking new revenue models for asset owners.

Investors highlight Suena’s potential as a shift-maker in energy trading software. Till Wyszynski of Eneco Ventures remarked, “Suena Energy impressed us with its outstanding team, innovative trading platform, and clear vision. The ability to optimize complex assets like the combination of renewables and storage in real time is a crucial element of the energy transition. Suena Energy has the potential to become a market leader in this space.”

Christian Bauer, Member of the Executive Board and CEO for the DACH region at InnoEnergy, added: “With its innovative approach, Suena Energy makes battery storage more economically attractive and takes it to the next level within the system. It is an indispensable element for a stable, renewable power grid, and Suena Energy therefore offers the perfect solution for the rapidly growing battery storage market in Germany.”

Suena plans to fast-track scaling its business model, shorten project development timelines, and continue honing its AI technology. Their goal is clear: to become the leading platform for intelligent, fully automated flexibility trading in Europe’s increasingly decentralized, decarbonized power sector.
