MT Group has signed a €27.8 million EPC turnkey contract with Pure Energy Solutions for the design, construction, and commissioning of a 35 MW/140 MWh battery energy storage system (BESS) facility in Rietavas, Lithuania.
The project will be directly connected to a 110 kV high-voltage substation operated by Lithuania’s Transmission System Operator (TSO), Litgrid, strengthening Lithuania’s flexibility and grid resilience. As renewable generation grows across the Baltics, the Rietavas BESS will provide frequency control and balancing reserves, supporting cross-border integration and participation in the Baltic and Nord Pool balancing markets.
Dr. Kristina Norvaišiene, Executive Director at MT Group, commented: “Rietavas BESS highlights MT Group’s commitment to delivering the next generation of smart energy infrastructure. BESS are becoming central to the modern power grid ensuring flexibility, supporting renewable generation and enabling a more interconnected Baltic energy market. This project is another step towards building a resilient, future-ready energy system for the region.”
Arturas Jacikas, CEO of Pure Energy Solutions, added: “This project demonstrates how strong local partnerships can accelerate the deployment of modern balancing assets. 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. 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.”
