The bankability instrument for battery storage.

Consulting firms send a PDF and an invoice. EnergyPassport delivers continuous, independent, cryptographically signed verification from credit package through debt maturity.

Auditable, peer-reviewable methodology
Tamper-proof signed records
No new hardware required
3D render of a utility-scale battery energy storage system
Independent third-party performance certification for battery energy storage systems

One IE report. Then 15 years of operator self-reporting.

A consulting firm charges $150-300K for a PDF that's stale at delivery. Then 15 years of operator-provided spreadsheets. No independent data. No early warning. No chain of custody.

TRADITIONAL IE FIRMS & CONSULTANTS
  • Send a team to site for 8-12 weeks
  • Deliver a PDF snapshot - stale immediately
  • Work from operator-provided BMS data
  • $150-300K per engagement
  • No cryptographic chain of custody
  • No continuous monitoring after delivery
  • Scale by hiring more consultants
SYNTHGRID ENERGYPASSPORT
  • Automated onboarding, no site visits required
  • Continuous verification for the life of the debt
  • Dual-telemetry: grid meter vs. BMS cross-check
  • One-time fee, bundled into the equipment package
  • Every record cryptographically signed and tamper-evident
  • Real-time degradation alerts and covenant monitoring
  • Scale with software, not headcount

The verification gap costs you money.

Higher DSCRs. Wider spreads. Shorter tenors. Conservative reserves. Rational responses to performance uncertainty, but they cost money on every deal.

DSCR
Coverage Ratios
Conservative DSCRs exist because lenders can't verify performance. Verified data changes the calculation.
Spreads
Risk Premiums
Solar monitoring compressed spreads 40-60 bps when third-party data became standard. BESS has the same information gap today.
Reserves
Maintenance Reserves
Without verified degradation data, reserves assume worst-case. Verified curves let you model from actuals, not assumptions.

Archival-grade report format

Designed for lender credit committees, insurance underwriters, and regulatory compliance. Every verification is auditable, reproducible, and tamper-evident.

Join the verification standard.

EnergyPassport sits between every party in the deal. We partner with the organizations that originate, finance, and build energy storage.

Put verification in your next financing proposal.

New build, refinancing, warranty dispute, or program compliance: the first step is a conversation.
