MT Group has signed a 27m EPC turnkey contract with Pure Energy Solutions for a 35MW/140MWh battery energy storage system in Rietavas, Lithuania.
The project will connect directly to a 110kV high-voltage substation operated by transmission system operator Litgrid to strengthen Lithuania’s flexibility and grid resilience.
MT Group said the Rietavas BESS will provide frequency control and balancing reserves as renewable generation expands across the Baltics.
The developer added that the facility will support cross-border integration and participation in the Baltic and Nord Pool balancing markets.

Dr. Norvaisiene said: “Battery Energy Storage Systems are becoming central to the modern power grid ensuring flexibility, supporting renewable generation and enabling a more interconnected Baltic energy market.”
She added: “This project is another step towards building a resilient, future-ready energy system for the region.”
“This project demonstrates how strong local partnerships can accelerate the deployment of modern balancing assets,” said Arturas Jacikas, chief executive of Pure Energy Solutions.
Jacikas said: “We are proud to have MT Group as the right EPC partner combining proven technical excellence, reliability and a deep understanding of Lithuania’s energy infrastructure.”
He added: “Rietavas BESS will set a new benchmark for large-scale storage projects, enhancing grid flexibility and cross-border stability across the Baltic and Nordic electricity markets.”
