PPC and METLEN plan 1.5GW storage portfolio JV across Romania, Bulgaria and Italy

PPC Group and METLEN Energy & Metals are jointly developing a substantial 1.5GW/3000MWh battery energy storage portfolio, strategically spanning Romania, Bulgaria, and Italy. This partnership targets the critical need for grid flexibility and renewable energy integration across Southern and Central European markets. The 2-hour duration implied by the 3000MWh capacity for 1.5GW suggests a focus on ancillary services and firming intermittent generation within these three distinct national grids. This development-stage joint venture allows both PPC and METLEN to share the capital expenditure and execution risks associated with building such a large, multi-country asset base. The agreement, announced on 2026-03-05, positions the two companies to capture value from the evolving energy transition across Greece's neighbors and a major Western European economy. The undisclosed value of this partnership indicates a focus on long-term asset creation rather than an immediate financial transaction. PPC Group, Greece's largest electricity producer and supplier, continues its transformation towards green energy with this 1.5GW storage development. Its strategy involves divesting lignite assets, making this battery portfolio a direct complement to its evolving generation mix and a geographical expansion beyond Greece. METLEN Energy & Metals, a global industrial and energy company with significant presence in both Energy and Metallurgy sectors, reinforces its position at the forefront of the energy transition through this 3000MWh storage commitment. This joint venture allows METLEN to expand its energy sector footprint across Romania, Bulgaria, and Italy, leveraging its industrial capabilities for large-scale infrastructure. Both counterparts are actively building future-proof portfolios in European markets demanding increased grid stability and renewable energy integration.
