Greece Inaugurates 330 MW Standalone BESS in Thessaly
Greece has officially commissioned its largest standalone battery energy storage system (BESS) to date, marking a significant milestone in the country's ongoing energy transition. The impressive 330 MW/790 MWh facility is strategically located in the Thessaly region. It was developed by a joint venture between METLEN Energy & Metals, holding a 49% stake, and Karatzis Group, which holds the majority 51% share. METLEN is also fully responsible for the construction, long-term operation, and maintenance of the project.
The development of this major infrastructure project was financially supported by a substantial loan from the European Union’s Recovery and Resilience Facility under the NextGenerationEU initiative. This highlights the critical role of EU funding in accelerating member states' decarbonization, grid stabilization, and renewable integration efforts across Southern Europe.
National Storage Targets Set for 2028
Alongside the commissioning of the Thessaly facility, Greek Prime Minister Kyriakos Mitsotakis has announced an ambitious national target for energy storage deployment. The government aims to have between 3 GW and 4 GW of energy storage projects, encompassing both advanced battery systems and traditional pumped hydro storage, either fully operational or under active implementation by the year 2028.
"The new 330 MW facility in Thessaly represents a crucial step towards Greece's goal of achieving 3-4 GW of storage capacity by 2028, reinforcing grid stability and integrating more renewables."
This strategic push positions Greece as a rapidly growing player in the European energy storage market. By leveraging both domestic regulatory initiatives and European financial instruments, Athens is actively modernizing its power infrastructure to accommodate higher penetrations of solar and wind energy.
