PPC Group and METLEN Energy & Metals have signed a joint venture agreement to develop up to 1,500 MW / 3,000 MWh of battery energy storage systems across Romania, Bulgaria and Italy.
The partnership establishes a new company owned equally by both parties and aims to accelerate deployment of large-scale storage supporting renewable energy growth across Southeast Europe.
The portfolio includes projects with a combined nominal capacity of up to 1,500 MW with around 1,000 MW expected to move forward within the next twelve months. The facilities will use two-hour liquid cooled battery systems based on advanced lithium iron phosphate technology designed to maximize usable energy output while maintaining high safety standards.
The collaboration combines complementary strengths in development construction and energy management. PPC Group brings an established operational presence in all three markets enabling rapid permitting development and energy management. METLEN contributes deep international experience and proven expertise in the engineering construction and delivery of complex energy infrastructure projects.
The storage stations will support nearby photovoltaic and wind parks by capturing surplus renewable power and releasing it to the grid during periods without sun or wind. In addition to improving renewable utilization, the projects will help stabilize electricity systems and strengthen regional energy security.
For both companies the partnership advances strategic energy storage ambitions in Europe while supporting the transition toward a resilient low carbon power system. This initiative also signals growing cross border cooperation in clean energy infrastructure investment across European power markets and grid resilience.
