Battery Storage Revenues Hit Record High in May 2025, Says Enervis Index

💡 Market Update – Enervis Battery Storage Index, May 2025

According to the latest Enervis battery storage index, utility-scale battery revenues in Germany soared to an all-time high in May 2025. This surge reflects a combination of increased price volatility, grid stress, and growing participation in balancing markets. On average, battery systems achieved over 10,000 EUR/MW in monthly revenue, primarily driven by activities in the intraday and balancing (FCR/aFRR) markets. These values mark the highest monthly returns since the index began. The Enervis analysts attribute the record to tight grid conditions, increased renewable penetration, and occasional negative pricing events that boosted arbitrage opportunities. 👉 Read the original German article here: 🔗 Enervis Battery Index: Record Revenues in May 2025
