Two independent data sources. Cross-referenced continuously. Auditable, independently verifiable data your counterparties can rely on.
Grid operators pay batteries to respond to frequency events. But the only proof of performance comes from the battery operator themselves. Self-reported data doesn't hold up in warranty disputes, refinancing conversations, or insurance renewals.
A 2025 analysis of over 100 fielded BESS systems found that 17% of BESS hardware failed to meet nameplate capacity at Site Acceptance Testing - before the warranty period even begins. EPRI's BESS Failure Incident Database found that 72% of failures occur within the first two years, and 89% trace to controls and balance-of-system - not cell defects. Lenders know this. That's why financing terms are worse than they should be - and why disputes drag on for months without resolution.
Read-only access to your BMS and the utility-owned revenue-grade meter. Two causally related data streams, cross-referenced for consistency. We never touch your controls.
Built to change financing terms.
Denied BESS warranty claims consistently fail on evidence. EnergyPassport monitors the parameters your warranty requires and documents compliance continuously - so the evidence exists before you need it.
Every report answers the questions lenders, insurers, and warranty counsel actually ask. No other verification provider catches all eight.
Traditional IE assessments check one or two of these. Operations dashboards check zero. EnergyPassport runs all eight continuously, with cryptographic chain of custody on every record.
