An A–F rating for battery energy storage across its whole life — from financing to underwriting to incident review. An overlay that sits on top of your BMS and analytics, not a replacement for them.
The rating updates continuously — cycle depth, thermal excursions and duty attributed to the grade, tracked against the LFP degradation shape-curve.
The LFP degradation model is validated in trajectory shape— sub-5% error against an LFP/MATR reference. That’s the chemistry most grid storage runs. NMC/NCA support is in progress and we don’t claim its accuracy yet. We’d rather scope the claim than oversell it.
The buyer. Grade the fleet of assets you own or operate — concentration risk, warranty posture, month-over-month movement.
Recognition. Underwriting-ready evidence, not a black box score — and we never fabricate a loss distribution. Better terms are a possible outcome of clearer evidence, never a guarantee.
Bankability. A pre-close grade and degradation envelope on the asset behind the loan — grounded in a validated model, not a spreadsheet assumption.
Start with one rack. Get a sample rating on the reference fixture, or scope a pilot on your own fleet.
