Greek energy and metals company Metlen has joined forces with shipping group Tsakos to develop a large-scale solar-plus-storage facility in Greece. The project, with a capacity of 252 megawatts, will combine photovoltaic generation with energy storage, though specific storage capacity details were not disclosed.

The joint venture was formalized on July 9, 2026, according to an announcement by the partners. The initiative aligns with Greece's ambitious targets for renewable energy deployment, as the country seeks to reduce reliance on fossil fuels and meet European Union climate goals.

Metlen, formerly known as Mytilineos, has been expanding its renewable energy portfolio, while Tsakos, primarily a shipping company, is diversifying into the energy sector. The partnership leverages Metlen's expertise in energy projects and Tsakos's financial and strategic resources.

Neither company provided a timeline for construction or commercial operation. The project is subject to regulatory approvals and grid connection agreements. Greece has seen a surge in solar investments, driven by favorable policies and declining costs for photovoltaic technology.
