- Financial layer included
- Beyond revenue: add CAPEX and OPEX and get the financial KPIs of the project in the same tool.
- Our team, alongside
- More than a tool: we support you from onboarding to daily use, with inputs, assumptions and how to get the most out of each simulation.
How it works
Input your data
Upload forward price curves and P50 generation profiles for your solar or wind assets. If you do not have them, our own curves are available.
Simulate and size
Configure power, capacity hours, depth of discharge, round-trip efficiency, degradation and the interconnection point. Run a single scenario or a batch to find the optimal size.
Analyse your results
Annual, monthly and daily revenue forecasts broken down by market, hourly energy flows and the financial KPIs of the project.
Inside the platform
A walk through what you see when you simulate your battery, from the hour-by-hour operation to the financial model.
See the operation, not just the result
OptiBESS shows the complete operation of the battery, day by day and hour by hour, so you understand exactly how each result was reached and can defend it in front of investors and lenders.
Compare every configuration
Layer a real financial analysis on each scenario to see which configuration maximises the return, and compare every variant side by side.
Three trading tiers
Tier 1, day-ahead only (arbitrage). Tier 2, day-ahead plus the secondary regulation band (aFRR). Tier 3, day-ahead and aFRR, optimising the split between the two.
A financial model you can export
Every simulation includes CAPEX, OPEX and year-by-year cash flow, with project payback, ready to download and share with investors or lenders.
