AI optimizer to trade Baltic hybrid solar-storage assets

Capalo AI, a Finnish company that optimizes battery energy storage systems across European electricity markets, has agreed to provide route-to-market and trading services for two hybrid solar-plus-storage projects owned by Danish developer European Energy in the Baltic region.

The first asset is the Anykščiai hybrid project in Lithuania, comprising a 78.5 MW solar park co-located with a battery connected in June 2026 at 25 MW/65 MWh. European Energy had previously announced financing for a 50 MW battery at the same site, but it is unclear from public disclosures whether the 25 MW/65 MWh system represents the final project configuration, a phased deployment, or a change from earlier financing plans. Capalo AI’s release describes commissioning and market prequalification for the asset as finalized in August 2026.

The second asset is the Saldus Hybrid Park in Latvia, where Capalo AI and European Energy describe the battery component as 46 MW/105 MWh. The project remains under construction.

European Energy’s own prior announcements have described the battery differently: an October 2025 announcement of European Energy’s sale of a 50% stake in the project to Danish pension fund Sampension cited a 46 MW rating, while a November 2025 financing announcement cited 92 MWh. It is not clear from public disclosures whether these figures describe the same final configuration as the newly announced 105 MWh.

Capalo AI said it will provide day-ahead, intraday and balancing-market trading, along with coordinated dispatch of the solar and battery components as a single flexible unit. The company also said it will provide balance responsible party (BRP) services for the Baltic assets. In Poland, by contrast, Capalo AI holds its own electricity-trading license but a third party, AARX Energy, serves as BRP, indicating the role can vary by market.

Capalo AI manages 1.6 GW of batteries and 460 MWp of solar under its Zeus VPP platform, with 600 MW and 300 MWp of that already live under trading and optimization. The company, founded in 2022, now operates in six European markets and plans to expand into five more this year. It also raised €11 million ($12.8 million) in a Series A round led by Heartcore Capital earlier this year.

Henri Taskinen, Capalo AI’s CEO, noted that European Energy has a large renewable-energy development portfolio. He said that Capalo AI expects the Anykščiai and Saldus assets to participate in Baltic balancing and wholesale power markets through its optimization platform.

European Energy Deputy CEO Jens-Peter Zink said battery storage and the hybridization of energy parks is becoming an increasingly important part of the company’s portfolio, and added that the Baltic countries are a particularly interesting market.

European Energy, headquartered in Copenhagen, reported €766 million in revenue and €170 million in EBITDA for 2025, with 662 MW of renewable capacity grid-connected during the year and a battery-storage development pipeline that grew from 2.4 GW to 7.4 GW over the same period.

The Baltic states have moved toward common regional balancing arrangements since synchronizing with Continental Europe, with Lithuania becoming one of the region’s most active battery storage markets. The country’s government has approved support for up to approximately 1.7 GW/4 GWh of new storage capacity.
