The global push for renewable energy has placed energy storage at the heart of Europe’s energy transition. On September 10, 2025, Finergreen announced that E Energy Invest (EEI), the investment vehicle of the Strioga Family Foundation, has acquired a 49% stake in FFNEV BESS, a major battery energy storage system (BESS) development platform in Europe, from FF Ventures. The deal, though undisclosed in value, marks a strategic partnership that promises to accelerate the continent’s clean energy ambitions.

The collaboration blends EEI’s strong investment capacity with FF Ventures’ technical expertise and development track record. While FF Ventures retains 51% ownership, the partnership is geared toward fast-tracking the development of FFNEV BESS’s 2.4 GW project pipeline. Positioned in high-demand regions like Spain, Portugal, and Romania, the platform is expected to deliver its portfolio to ready-to-build status within two years. These regions are not only witnessing growing electricity demand but are also backed by clear government commitments to scale battery storage solutions.

Each target market holds significant potential. Spain, through its National Energy and Climate Plan, aims for 12.5 GW of storage by 2030 and has recently launched a capacity market to support this goal. Portugal has aligned its renewable energy roadmap with a 2 GW BESS target, while Romania has set milestones of 1.2 GW by 2030 and 1.5 GW by 2035, supported by a new competitive grid connection scheme set for early 2026. Together, these policies create fertile ground for FFNEV BESS projects, including 14 sites in Spain, 12 in Romania, and a robust pipeline prepared for Portugal’s upcoming capacity auctions.

The transaction underscores how collaboration between financial investors and renewable developers is essential for meeting Europe’s energy storage targets. With development expenses projected at around €5.6 million over the next four years, the platform is designed to absorb both grid-related and construction challenges. Beyond delivering new capacity, the partnership also ensures that incoming BESS partners hold pre-emption rights on projects as they mature, offering a competitive edge in scaling the portfolio. By accelerating deployment, this move strengthens Europe’s ability to integrate renewables more efficiently, ensuring grid stability and reliability.

As the demand for storage solutions intensifies, partnerships like this set the tone for the continent’s clean energy transition.
