Europe's Batteries Are Big. Are They Smart?

Capalo AI secures €11M to scale its AI-powered virtual power plant across Europe's fast-growing battery storage market

14 May 2026

Europe's battery storage sector is building capacity at record pace. The missing piece, in many markets, is the software to extract full value from it.

Capalo AI, a Helsinki-based energy technology company, has raised €11 million in a Series A round led by Heartcore Capital, with Tesi and returning investors participating. Proceeds will finance expansion of its artificial intelligence platform, which dispatches large-scale batteries across European electricity markets in real time.

Behind the deal sits a broader shift. Hardware costs for battery storage have fallen sharply, and grid connection pipelines are increasingly congested. Competitive advantage now sits in optimisation software, and capital is following accordingly.

Founded in 2022, Capalo AI operates what is known as a virtual power plant: a system that connects batteries and co-located renewable assets, then trades their output simultaneously across balancing and ancillary service markets. By the end of 2025, contracted capacity exceeded 1 gigawatt across Finland, Sweden, Latvia and Lithuania. Further European expansion is planned for 2026.

Commercial results reinforce the pitch. Across Nordic markets, battery operators using multi-market dispatch strategies have reported revenues 30 to 50 per cent above initial projections.

Henri Taskinen, chief executive, said: "Infrastructure alone cannot solve this challenge. Intelligently orchestrated battery storage is now critical to accelerating the renewable energy ramp-up."

His remarks come as Europe installed a record 27.1 gigawatt-hours of battery storage in 2025, a 45 per cent increase year on year. Utility-scale projects led deployment for the first time.

Yet scaling a software platform across the continent carries friction. Regulatory frameworks, metering standards and balancing market designs differ sharply between countries. Operating in five or six jurisdictions simultaneously demands not only technical flexibility but deep local regulatory knowledge.

Whether pan-European virtual power plant platforms can maintain performance at that breadth remains an open question.

Investors appear willing to back the attempt. Europe's battery storage capacity is projected to surpass 50 gigawatts by 2030. How much of that value is captured may depend less on the assets themselves than on the intelligence directing them.
