Overview How It Works Health Estimator For Lenders For Operators EPC & Warranty Government Programs OEM Partners Contact

Prove what your battery delivered.

Independent performance certification for battery storage. Continuous dual-telemetry verification that closes lender credit files, defends warranty claims, and replaces operator self-reporting with third-party proof.

Auditable, peer-reviewable methodology
Tamper-proof signed records
Read-only data access
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.

See the EPRI field evidence
EPRI found vendors reporting battery health at 99.5% while independent measurement showed 96.5% - a degradation rate seven times faster than reported. The data your models rely on is the data the operator chose to share.

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. CAISO data shows storage unavailability at 8.9% - nearly 3x higher than solar.

COVERAGE RATIOS
TODAY 1.35x WITH SYNTHGRID 1.20x
DSCR compression
Conservative DSCRs exist because lenders can't verify performance. Verified data changes the calculation.
RISK PREMIUMS
SOLAR 2013→2018 -40 to -60 bps compression
Spread compression
Solar spreads compressed 40-60 bps when third-party data became standard. BESS has the same gap today.
