BESS Index - Operational & Multi-Market Benchmarking
A transparent, market-driven BESS revenue benchmark for Germany, the Netherlands and Belgium - combining realistic trading models, multi-market revenue stacks, and configurable battery assumptions. Delivered via the Montel EnAppSys platform.
Key capabilities
Montel’s battery analytics are informed by extensive work representing over €1 billion in financed projects and 1 GW of installed capacity. This foundation helps ensure the BESS Index delivers realistic, credible and actionable benchmarks.
Built for battery developers, operators and traders, it reflects how BESS assets actually perform across European power markets accounting for trading constraints, market liquidity and asset configuration.
Analyse how battery revenues are generated across all relevant market layers, including Day-Ahead, Intraday and balancing services such as aFRR.
The breakdown shows the contribution of each market, helping you understand where value is created and how different revenue streams interact.
Benchmark more than 80 battery setup variants by adjusting power, energy duration, state of charge and cycle limits.
This allows benchmarks to be aligned closely with your asset’s real-world operating context and trading strategy.
Assess both realistic and theoretical revenue scenarios using multiple benchmark models, including Perfect Foresight, Market Practice and Continuous Intraday.
Comparing these models provides upper and lower reference points and helps identify achievable performance.
Combine highly granular daily results with long-term historic data to uncover trends, evaluate strategies and analyse performance over time.
This supports both short-term assessment and longer-term strategic planning.
Visualise results through customisable dashboards, charts and tables, or access the data directly via API feeds.
This ensures the BESS Index integrates seamlessly into existing tools, workflows and analytical environments.
