Data Analysis: Public Support and Revenue Predictability for European BESS
Europe is expected to install over 30 GW of batteries in 2026, marking a historic year for the energy storage sector. However, a detailed data analysis reveals stark contrasts in public support and revenue predictability across member states, heavily influencing project bankability and merchant risk.
Divergent National Strategies
For front-of-the-meter battery capacity expected between 2025 and 2030, the share derived from auctions, tenders, or public support varies dramatically. Bulgaria exceeds 90% public support, with up to 50% of battery investment funded directly by European funds, making it the fifth-largest global market for new capacity in 2026. Poland follows closely at around 85%, having awarded battery contracts of up to 17 years in its capacity market. Italy and France also exceed 70% public support.
Germany has the highest merchant exposure in Europe, with below 20% public support, relying heavily on 5- to 10-year tolling agreements.
In contrast, Germany's capacity market remains unapproved by the European Commission as of September 2026. Consequently, Germany relies on tolling agreements and accounts for 15% of Europe's contracted battery capacity. Meanwhile, Spain recently published Order TED/966/2026, creating a capacity market with an estimated €9 billion budget over ten years, allowing new storage facilities to secure contracts of up to 15 years. Italy also held its first MACSE auction in September 2025, awarding 10 GWh with 15-year contracts, providing vital state-backed risk mitigation.
