On February 9, 2025, Lithuania officially synchronised with the Continental Europe Synchronous Area (CESA) and left BRELL. Beyond political implications, synchronisation with Continental Europe meant that the premium on domestic accurate flexibility grew, with strong push to modernise balancing and bring flexible assets into the market.
In 2025, the Lithuanian TSO Litgrid, alongside its Baltic peers, connected to both the PICASSO platform for aFRR energy and joined MARI for mFRR energy. Simultaneously, the Baltic Balancing Capacity Market continued its rollout, creating a level-playing-field for solar, wind, and flexible demand.
Following these changes, in July 2025, the first solar park entered into Lithuania’s balancing market with Centrica Energy as the balancing service provider. The success of the project reframes solar and wind assets from “challenging to integrate” into reliable contributors to grid balancing and lower costs.
Through ReFlex, solar and wind resources support system stability at a lower overall cost, delivering clear technical, economic, and commercial benefits whilst strengthening energy independence. Competition deepens, which over time helps tighten spread and reduce average balancing costs for consumers.
Harmonised platforms and transparent settlement processes also improve investment clarity, de-risk cash flows and can further strengthen the bankability of solar and wind portfolios. At the same time, local flexibility enhances security of supply, reducing reliance on costly redispatch.
Introducing first-of-its-kind solar flexibility
Our ReFlex solution is delivering those benefits in practice, with European Energy’s Meiluškiai solar park demonstrating the opportunities, and becoming the first solar asset in Lithuania to enter the balancing market in July of 2025.
As a front-runner in Renewable Flexibility, we were the first to prequalify renewable flexibility from solar in Lithuania. Completing end-to-end prequalification and BSP setup with Litgrid, including telemetry and control testing aligned to TSO requirements while protecting the sites energy generation, the solar park now delivers mFRR services. Acting as both BSP and BRP, we transformed this concept into daily operations, proving that solar assets can participate effectively under EU-harmonised rules.
Through ReFlex, our portfolio of renewable assets gains compliant access to balancing markets. Algorithmic bidding operates 24/7, coordinating day-ahead, intraday, and balancing strategies tuned to Baltic liquidity and market conditions. Integration is seamless, with rigorous screening and transparent audit-ready reporting.
This milestone provides a clear commercial proof point and establishes a repeatable model for integrating additional solar and wind assets into balancing markets. It marks a significant step toward a more resilient, cost-efficient, and sustainable energy system.
