Diverse Revenue Models Across EU Member States
The development of front-of-the-meter (FTM) battery storage across the European Union is characterized by divergent business models. In countries like Bulgaria, Poland, and Italy, FTM storage is heavily driven by government auctions, support mechanisms, and contracted revenues. In stark contrast, Germany's market is predominantly merchant-oriented, relying on private contracts such as tolling agreements to secure project bankability.
Central and Southeastern Europe Emerges
Bulgaria has emerged as one of the top European markets for battery storage in 2026, largely driven by resources from the European Union's recovery funds. This highlights the rapid expansion of energy storage infrastructure in Central and Southeastern Europe, moving beyond the traditional Western European strongholds.
Hungary's Ambitious Storage Targets
Hungary is also making aggressive moves to bolster its grid flexibility. In early 2026, the Hungarian government launched an energy storage subsidy program totaling approximately 100 billion HUF, aiming to support at least 800 MW of new capacity. According to system operator Mavir, Hungary's current BESS capacity is nearly 1 GW, with a strategic target to reach up to 5 GW by 2031 to cover 20-30% of solar and wind generation.
Chinese supplier Welion recently signed a 150 MWh framework agreement with Hungarian company Szermann Kft, and a 50 MWh agreement with Romanian company HOSTIX Zso, signaling strong supply chain activity in the region.
These regional developments underscore the EU's diverse but unified approach to integrating renewable energy, leveraging both market-driven and policy-supported mechanisms to achieve continental climate goals.
