4impact capital joins €8 million Series A round in suena energy

suena energy, a German technology company specializing in algorithmic optimization and trading for energy storage systems and renewable energies, has successfully closed an €8 million Series A funding round. The round was led by Dutch energy company Eneco through its investment arm, Eneco Ventures, with strong participation from 4impact capital. Existing investors InnoEnergy, J.O.S.S., Santander, and Energie 360° also participated.

suena energy will use the fresh capital to strengthen its position in the rapidly growing energy storage market – with a focus on international expansion, scaling its business model, and optimizing the co-location of storage systems with renewable energy assets.

AI-powered trading for the energy transition

suena energy’s proprietary Energy Trading Autopilot enables fully automated, AI-driven trading of flexibilities across all relevant power and ancillary service markets. Using real-time data and forecasts, the platform generates optimal dispatch schedules to maximize revenues while minimizing risk and battery degradation.

A key focus of the growth strategy is the rapidly expanding market for co-located storage. These projects not only offer operational synergies and new revenue models but also require strong technological, regulatory, and economic integration. suena energy addresses this complexity with a software approach that can flexibly adapt to market and project conditions, helping customers to develop storage projects quickly, efficiently, and profitably – for a resilient, decentralized, and decarbonized power system.

Strategic investors supporting growth

“This funding round marks a strategic milestone for us, enabling us to take our business model to the next level – with strong partners at our side who share our vision”

said Lennard Wilkening, PhD, Co-Founder and CEO of suena energy.

“Eneco Ventures and 4impact are highly complementary to our existing investor base. Their strategic-operational and digital technology expertise bring us closer to our goal of becoming a leading provider of intelligent flexibility trading in Europe.”

Eneco brings its expertise in building and operating scalable, decentralized energy solutions as a leading energy company with a robust footprint in electrification and sustainable infrastructure to the table, along with a strong market presence in Germany, the Netherlands and other European countries. Eneco Ventures leverages Eneco’s extensive operational expertise and networks and partners closely with visionary entrepreneurs to scale transformative, climate-positive technologies.
