The storage stations will use two-hour liquid-cooled battery systems featuring LFP technology, maximising both usable energy output and operational safety. The two companies are combining their expertise in development, construction and energy management, with PPC Group providing rapid project development and energy management capabilities across all three countries, while Metlen contributes its construction experience and know-how.

Beyond supporting photovoltaic and wind parks by storing surplus energy for injection into the grid during periods without sun or wind, the storage stations will contribute to electricity system stability. The investments will ensure optimal use of electricity generation from renewable energy sources and enhance power system stability across the region.

For PPC Group, this agreement secures implementation of a portion of its energy storage target over the next three years while ensuring rapid execution and construction quality. The projects will be geographically diversified across countries where the group already operates and located near renewable energy projects to optimise performance.

Konstantinos Mavros, Deputy CEO, Renewables of PPC Group, stated: "This agreement creates value for both parties and further expands our Group's presence in Southeast Europe. The energy storage projects will ensure optimal use of electricity generation from renewable energy sources and the stability of the electricity system in our country and across the entire European continent." Nikos Papapetrou, Chief Executive Director, Renewables, Storage & Energy Transition Platform of Metlen, added: "By combining Metlen's international experience and expertise with PPC's strong presence in regional markets, we demonstrate that energy storage is a catalyst for maximising the value of renewable energy sources and ensuring the reliability of power systems."
