BESS Portfolio Management with One Consistent Methodology.
Catalyst enables battery storage portfolio analysis across all your projects — same assumptions, same optimization logic, consistent metrics — comparable, scalable, ready for decisions.
Trusted by leading portfolio managers
The Problem
The Hidden Cost of Inconsistent BESS Portfolio Methodology
When 10 projects are evaluated in 10 different spreadsheets, a meaningful portfolio comparison is barely possible. Different assumptions, different methods — and ultimately a picture that nobody truly trusts. This becomes critical when institutional investors or lenders request portfolio-level reporting: inconsistent methodology creates gaps that are difficult to explain and even harder to defend. As portfolios scale, the problem compounds — each additional project adds another layer of methodological inconsistency.
The Solution
Battery Storage Portfolio Analysis — One Methodology for Every Asset
Catalyst brings all projects into a unified model. Same degradation assumptions, same market data, same optimization logic — making projects truly comparable. Portfolio decisions become a question of data, not trust. The platform handles any number of projects simultaneously, applying the same physics-based modeling framework across all sites. When market conditions change or lenders request updated stress scenarios, the entire portfolio can be recalculated consistently — not project by project, but all at once.
The Market
Portfolios are growing faster than the tools to manage them.
Inconsistent methods across projects
If every team uses its own spreadsheets, portfolio comparisons are methodologically worthless.
Regulatory and bank requirements
Investors and lenders expect uniform stress-test scenarios across the entire portfolio.
Growing project pipeline
More projects mean more variables — without scalable software, teams lose oversight.
The Platform

Key Features
For teams that need pipeline depth with consistent methodology.
Managing a growing BESS portfolio requires more than a collection of individual analyses. Catalyst enables portfolio managers to apply a single methodology across all assets, ensuring that performance metrics remain comparable regardless of project size, location, or technology. Stress tests, sensitivity analyses, and return rankings can be run across the full portfolio — giving teams the depth to make confident acquisition and allocation decisions.
Portfolio-Wide Stress Test
Test all projects simultaneously under the same market scenarios — and see instantly which ones perform the most stably.
Consistent Degradation Modeling
Uniform physics parameters across all projects ensure that long-term forecasts remain comparable.
Ranking by Return Criteria
NPV, IRR, DSCR — automatically calculated and ranked for all projects at once.
Energy Storage Asset Management Across Your Entire Portfolio
From quarterly investor reporting to acquisition screening, Catalyst supports every stage of active portfolio management. The platform's unified model ensures that results are directly comparable across assets — enabling portfolio managers to identify underperforming projects, validate new opportunities, and respond to lender requests with consistent, auditable documentation.
Quarterly Reports and Investor Updates
Consistent metrics for all projects at the push of a button — directly for board presentations and LP reporting.
Acquisition Screening
Quickly check new project opportunities for portfolio compatibility and return expectations.
Sensitivity Analysis at Portfolio Level
How does portfolio value change if the electricity price rises? Catalyst gives you the answer in minutes.
