METLEN and Tsakos Group have started construction on a hybrid renewable energy project located in Domokos, Greece, comprising a 251.9MW photovoltaic power plant combined with an energy storage system (ESS).
The work began after a groundbreaking ceremony attended by representatives from the Hellenic Parliament, local authorities, and business organisations.

The project is being developed through a jointly owned special purpose vehicle, with Tsakos Group holding a 60% interest and METLEN owning 40%.
This initiative involves integrating the power plant with an ESS expected to have a capacity of 375MWh.
METLEN is responsible for both the construction and the ongoing energy and commercial management of the facility.
According to the companies, the project aims to play a key role in Central Greece’s energy landscape by combining clean energy generation with large-scale storage capabilities.
The initiative could promote growth and generate wider benefits for the region, with a focus on collaboration with local stakeholders, stated the companies.
Tsakos Group founder Panagiotis Tsakos said: “Today is a special day for all of us and, for me personally, even more so. It marks the beginning of an important project, as well as our contribution, through our own efforts, to shaping a more sustainable energy future for our country.
“This is a project that is not only about generating electricity. It is about harnessing the natural potential of the Greek land, technological progress, energy security and, above all, our responsibility towards future generations.”
The start of construction is viewed by both companies as a milestone in their cooperation, which they say could support the development of next-generation energy infrastructure in Greece.
METLEN executive chairman Evangelos Mytilineos said: “Together with Tsakos Group, we are moving forward with an investment of particular significance for the country’s new energy system, leveraging METLEN’s expertise and international experience in the construction and management of complex energy projects.
“At the same time, we want this project to develop in close connection with the region and to create meaningful value for the local community and the Greek economy.”
Last month, Greece launched a standalone battery energy storage system (BESS) in Larissa, Thessaly, following a joint investment by METLEN and the Karatzis Group of Companies.
