Lithuania’s Anykščiai Solar Park Adds 65 MWh Battery System

Lithuania’s renewable energy infrastructure has taken a significant leap forward with the completion of a major battery energy storage system. Developer European Energy has successfully finished the construction of a 65 MWh battery park, which has been integrated into its existing 78.5 MW Anykščiai solar park. This development marks a crucial step in enhancing the country’s energy grid stability and maximizing the potential of its solar resources.

A Hybrid Leap with Lithuania solar battery Integration

The addition of the 65 MWh battery transforms the Anykščiai solar park, one of the largest in the Baltic region, into a sophisticated hybrid renewable energy facility. This integration allows the plant to capture and store excess solar power generated during periods of high production and low demand. The stored energy can then be dispatched back to the grid during peak demand hours or when solar generation is low, ensuring a more consistent and reliable power supply.

This project is a landmark for the nation, creating one of Lithuania’s first hybrid parks. According to statements from European Energy, the fully operational solar park was already the country’s first to be connected to the electricity balancing market. The new battery system, scheduled to begin operations in February 2026, will significantly enhance this capability.

Enhancing Grid Stability with Lithuania solar battery Systems

The primary function of the battery system extends beyond simple energy storage. It is designed to provide essential balancing services to the national grid. As more variable renewable sources like solar and wind are added to the energy mix, maintaining grid frequency and stability becomes increasingly complex. Battery storage systems can respond in milliseconds to grid fluctuations, absorbing or releasing power as needed to maintain equilibrium.

Tadeušas Konkovskis, European Energy’s Vice President and Head of the Baltic region, has highlighted that energy storage is key to managing the variability of renewables and ensuring stable grid operations. By storing energy, the facility mitigates the risk of curtailment—where renewable output is deliberately reduced because the grid cannot handle it—and helps to reduce price volatility in the energy market.

A Milestone for the Baltic Region: Lithuania solar battery Project

The Anykščiai project represents European Energy’s first battery system in the Baltic states, underscoring the company’s commitment to expanding its renewable capacity in the region. This development aligns with a broader strategy focused on asset optimization, strategic partnerships, and transactions to bolster the green energy transition in the Baltics.

By successfully pairing a large-scale solar farm with a substantial battery storage unit, Lithuania is setting a powerful example for the region. This forward-thinking approach demonstrates how to effectively integrate renewables, enhance energy independence, and build a more resilient and flexible power grid for the future.
