Capalo AI and Future Energy Partner to Optimize 56 MW / 168 MWh Lithuanian Battery Storage Project
MT Group is delivering the EPC infrastructure for the three-hour BESS, bringing together large-scale energy infrastructure, grid integration and AI-powered optimization.
Helsinki and Lithuania, 1 September 2026 – Capalo AI, a sustainable technology company specializing in optimization and trading of renewable and hybrid energy assets, has entered into a partnership with Future Energy, a Lithuanian renewable energy developer, to manage and optimize a 56 MW / 168 MWh standalone battery energy storage system (BESS) in Raseiniai, Lithuania.
The project brings together infrastructure investment, EPC delivery, and AI-driven optimization in one of Lithuania’s most significant new battery storage developments.
The BESS is planned to be completed by the end of 2026 and is expected to reach commercial operation in Q1 2027. Under the partnership, Capalo AI will provide route-to-market services for the asset, including Day-Ahead, Intraday and balancing market trading, as well as Balance Responsible Party (BRP) services, delivered through the Capalo Zeus VPP™.
With a storage capacity of 168 MWh, the Raseiniai BESS will be one of the largest facilities of its kind in Lithuania and among the country’s first commercial battery storage projects capable of storing and supplying energy for up to three hours. The longer storage duration enables more efficient participation across balancing and wholesale electricity markets while providing a broader range of services supporting the electricity system.
The facility is being delivered by MT Group, a European EPC contractor specializing in energy infrastructure. MT Group is responsible for the engineering, procurement and construction of the BESS infrastructure and its integration into Lithuania’s high-voltage electricity system. The battery park will be connected to the Litgrid 110 kV transmission network through the expanded Raseiniai transformer substation.
Together, Future Energy, MT Group and Capalo AI combine energy infrastructure investment, EPC delivery and advanced market optimization, connecting the physical infrastructure required for the energy transition with the digital capabilities needed to operate it efficiently.
The project has also been welcomed by the Raseiniai District Municipality as a significant investment in the region and a contribution to Lithuania’s ongoing energy transformation.
“Lithuania’s storage market is scaling quickly, with grid operators fast-tracking new battery connections to keep pace with the country’s growing renewable capacity. We already manage a substantial number of assets in the market, and this partnership with Future Energy extends that footprint and reflects the confidence Baltic developers continue to place in our trading and optimization approach” said Dainius Velykis, Regional Manager, Baltics, Capalo AI.
Rimvydas Štilinis, CEO, Future Energy, said: “Energy storage is becoming an essential part of Lithuania’s energy system. As renewable generation continues to grow, the ability to store electricity, provide flexibility and respond efficiently to market and grid needs becomes increasingly important. The Raseiniai project is a significant long-term investment in this infrastructure. By combining MT Group’s EPC capabilities with Capalo AI’s route-to-market access and AI-driven optimization, we are building an asset designed not only to store energy, but to operate efficiently across Lithuania’s evolving electricity markets.”
“Battery storage is becoming a fundamental part of Europe’s energy infrastructure. Projects such as Raseiniai demonstrate that the next generation of energy systems requires not only new renewable generation, but also large-scale flexibility, intelligent operation and strong grid infrastructure. At MT Group, our role is to turn this transition into physical infrastructure – engineering and delivering the assets that make a more flexible and resilient energy system possible. We are pleased to deliver this project together with Future Energy and to see Capalo AI bring advanced optimization capabilities to its operation,” said Phd Kristina Norvaišienė, Executive Director of MT Group.
Capalo AI’s Capalo Zeus VPP™ provides route-to-market access, AI-optimized trading and operational management of BESS assets, combining automated dispatch with a data-driven approach to maximizing revenue across multiple electricity markets.
