Problems we solve

Battery revenues change as markets evolve. New capacity, changing market design, renewable build-out and demand growth can all impact future returns.

Flex Insight helps answer not just "What could my battery earn?" but "How does that answer change when the future changes?"

Battery investments depend on assumptions about future market value. Flex Insight helps answer the questions developers, investors and lenders face when evaluating projects.

Flex Insight combines long-term power market forecasts with battery-specific assumptions to estimate revenues over horizons of up to 25 years. Users can assess both annual and cumulative revenue potential under different scenarios.

Battery revenues are influenced by competition and market saturation. Flex Insight allows users to assess future revenue potential under evolving market conditions and changing capacity outlooks.

Revenue forecasts are broken down across wholesale and balancing markets, helping users understand how value shifts over time and where future opportunities may emerge.

Run alternative scenarios using different assumptions and sensitivities to understand downside risks, upside opportunities and the robustness of your business case.

Flex Insight is powered by Montel Long-Term Curves (powered by Energy Brainpool), built using transparent market assumptions and regularly updated outlooks extending to 2050.

Evaluate long-term project value

Battery revenues can change significantly over time as market conditions evolve.

Flex Insight enables you to build long-term revenue outlooks of up to 25 years, helping you understand how project economics may develop across different market environments. Instead of relying on a single revenue assumption, you can evaluate multiple future pathways and gain a clearer view of both opportunity and risk.

Compare scenarios and sensitivities

Investment decisions are rarely based on one forecast.

Flex Insight allows you to test alternative assumptions and compare outcomes within a single modelling framework. Assess how revenues change under different market conditions, battery configurations, operational strategies or market participation assumptions. This helps identify the factors that have the greatest impact on project performance.

Model real-world project constraints

Every battery project is different.

Flex Insight allows users to incorporate battery specifications, co-location arrangements, grid constraints and market allocation assumptions into their analysis. This creates a more realistic view of future revenue potential and helps stakeholders understand how project design choices influence long-term outcomes.

Questions Flex Insight helps answer

  • What could my battery earn over the next 25 years?

    Build long-term revenue projections using Montel's power market outlooks and project-specific assumptions. Evaluate future merchant revenues across multiple market environments and understand how earnings may evolve over the asset lifetime.

  • How sensitive is my project to future market conditions?

    Compare multiple scenarios and sensitivities to understand how changes in market assumptions impact project economics. Assess downside risks, upside opportunities and the robustness of your business case.

  • How do different battery configurations compare?

    Test alternative battery durations, power ratings and operational assumptions to understand which configurations deliver the strongest long-term performance.

  • What is the impact of co-location and grid constraints?

    Model the effects of solar, wind or demand co-location alongside grid connection limitations and market allocation assumptions. Understand how these factors influence future revenues and project value.

  • Which revenue streams are expected to drive value?

    Analyse projected revenues across wholesale and balancing markets, helping you understand how value creation changes over time and which services contribute most to project performance.

  • Can I use this to support investment decisions?

    Flex Insight provides a transparent framework for evaluating battery opportunities, comparing business cases and supporting internal investment discussions, project development and financing processes.
