The alpha is where underwriting is hardest.
BESS and co-located assets carry higher complexity — and higher return potential. Catalyst gives investment teams the analytical depth to underwrite these assets with conviction, and the reforecasting capability to stay ahead when market conditions shift.

What Catalyst does for investment teams
Underwriting with conviction
BESS and co-located assets are analytically demanding — multiple revenue streams, regulatory constraints, configuration dependencies. Catalyst models the full complexity: multi-market dispatch, FCA quantification, co-location effects. Not an approximation — a real projection.
Reforecasting when markets shift
Market conditions change — regulation, pricing environment, competitive dynamics. Catalyst makes it possible to update projections quickly when assumptions shift: without rebuilding models from scratch. Investment teams stay current without re-running entire analyses.
Risk quantification that holds up
Know exactly what drives IRR — and where the risk sits. Catalyst makes the IRR sensitivity to market assumptions, regulatory exposure (FCAs, grid fees) and technical degradation transparent. No black box — an auditable foundation that survives scrutiny.
Consistency across the portfolio
The same modelling methodology for every asset in the portfolio — comparable, auditable, bankability-ready. Single project or 10-asset portfolio: Catalyst delivers a consistent foundation for LP reports, investor materials and internal investment committee review.
What a model needs to do for investment teams
Every assumption explicit — no black-box output that a lender or co-investor cannot trace.
Base case, bull, bear — and the ability to switch quickly to new scenarios when market conditions shift.
Standalone BESS, green storage, co-location hybrid — different configurations, different revenue stacks, different risk profiles. Catalyst models the difference.
Documentation that holds up to independent review. Bankability Certificates as a standardised output.
