Battery Storage Feasibility Studies — Auditable and Financing-Ready.
Catalyst is the battery storage modeling software for European project developers: physics-based dispatch optimization, full degradation, and auditable outputs — in hours instead of weeks.

The Problem
Why Spreadsheet Models Fail BESS Due Diligence
Project developers spend months with models that fail during the first bank meeting. Assumptions are undocumented, scenarios not reproducible — and the result is doubted before the actual examination even begins. The issue is structural: generic spreadsheet tools were never designed for the complexity of modern BESS projects. Multiple revenue streams, hardware degradation, grid constraints, and varying regulatory frameworks demand a purpose-built approach — one that produces results banks and investment committees can actually verify.
The Solution
Physics-Based Battery Storage Modeling — Built for Project Finance
Catalyst models every project site in physics-based depth: 15-minute dispatch optimization, complete degradation modeling, and auto-generated outputs that investment committees and banks can trace and verify. The platform was designed from the ground up for the requirements of BESS project development in Europe: transparent assumptions, reproducible scenarios, and documentation that does not require manual preparation before it can be shared with financing partners. The result is a feasibility study that holds up — not just internally, but in every external review.
The Market
Every project is under time and financing pressure.
Competition for limited grid capacity
Suitable locations are becoming scarcer. Whoever has reliable numbers earlier secures the advantage.
Increasing demands from banks
Spreadsheets are no longer enough for financing partners. They expect reproducible, auditable models.
Hybrid revenue stacks as standard
FCR, aFRR, DA, and EEG cooperation must be evaluated together — not in isolation.
The Platform
Catalyst — techno-economic BESS modeling.
Purpose-built for battery storage. All revenue streams, physics-based degradation, and auditable outputs — in one consistent model.

Every dispatch interval traceable
Key Features
For teams that need pipeline depth with consistent methodology.
Catalyst gives project development teams the analytical depth to move quickly without sacrificing quality. Each scenario run covers the full revenue stack — FCR, aFRR, day-ahead trading, and EEG cooperation — while accounting for battery degradation on a monthly basis. The result is a model that proves economic viability before a single euro is committed to a site.
Scenario Analysis in Minutes
Hundreds of scenarios per run, automatically ranked by NPV and IRR. This way, you quickly see which configuration makes the project viable.
Auditable Documentation
All calculations are fully traceable. No black-box output — but a model that holds up in a bank meeting.
Physics-Based Degradation
Calendar and cycle degradation according to real battery chemistries — not as a blanket deduction, but modeled on a monthly basis.
From BESS Site Screening to Bankable Feasibility Study
Whether you are evaluating a greenfield site, comparing technology options, or preparing a financing package, Catalyst adapts to your stage in the project development process. All outputs are produced from a single, consistent model — so that results from site screening to final documentation remain fully comparable and audit-ready.
Site Screening
Quickly compare multiple locations and identify the most profitable options — before expensive assessments are commissioned.
Auditable Feasibility Study
Catalyst outputs are used directly as a basis for financing documents — without manual post-processing.
Technology Comparison
LFP vs. NMC, various C-rates, different system sizes — all variants in one consistent model.
