Bankable Energy Storage Models for Project Finance Teams.
Catalyst generates BESS project finance documentation directly from the model: fully documented, traceable, and comprehensible for banks and investment committees.

The Problem
Opaque BESS Models Block Project Finance
Financing rounds rarely fail due to bad projects. More often, they fail because of opaque models that cannot withstand independent scrutiny. Banks and investors need transparency — Catalyst delivers it. The underlying issue is that traditional project models were not built with lender review in mind. They are designed for internal decision-making, not for the structured due diligence that project finance requires. Every undocumented assumption becomes a question in the bank meeting — and every unanswerable question delays the financing timeline.
The Solution
Auditable BESS Project Finance Documentation — Every Assumption Traceable
Catalyst generates fully traceable calculations based on physically grounded models. Every assumption is documented, every dispatch value is traceable — the result is documentation that passes the financing interview. Unlike black-box tools or manually assembled spreadsheets, Catalyst produces outputs that are inherently audit-ready: the model logic is transparent, the scenario inputs are explicit, and the results can be verified by independent technical advisors. This means less time spent in due diligence preparation and more confidence going into every bank meeting.
The Market
Bank financing for BESS often fails because of documentation.
Increasing lender requirements
Banks expect reproducible models with traceable assumptions — spreadsheets have long ceased to be enough.
Long due diligence processes
Unclear model documentation prolongs due diligence phases by months — and costs capital.
Complex revenue stacks
Multiple simultaneous revenue streams make economic modeling complex — and error-prone when done manually.
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.

Key Features
For teams that need pipeline depth with consistent methodology.
Catalyst was built with the requirements of project finance in mind. All model outputs are structured so that financing partners can trace every calculation step — from input assumptions through dispatch optimization to the final DSCR. Sensitivity analyses can be configured to mirror lender-specific stress scenarios, and all results are exportable in formats that can be incorporated directly into financing documentation.
Auditable Documentation
Catalyst outputs are used directly as appendices for financing documents — without manual preparation or post-processing.
DSCR Analysis and Sensitivities
Debt Service Coverage Ratio over the entire project lifetime — under stress scenarios that lenders can define themselves.
No Black-Box
Catalyst is not an AI black box. All calculation steps are transparent and verifiable by independent auditors.
From BESS Model to Battery Storage Lender Report
The gap between an internal feasibility study and a bankable financial model is often where BESS projects get stuck. Catalyst closes this gap by producing documentation that serves both purposes: analytically rigorous enough for internal decision-making and sufficiently transparent for external review. From initial term sheet discussions to final credit approval, Catalyst provides the analytical foundation that financing processes require.
Create Financing Documents
Catalyst outputs form the analytical basis for teasers, term sheets, and financial models — in auditable quality.
Due Diligence Support
All model assumptions and results are fully documented and ready to provide upon request during technical due diligence.
Lender Stress Test
Simulate the requirements of your financing partners: custom price paths, conservative degradation scenarios, varying utilization assumptions.
