Cross-referenced BMS and grid-side records for underwriting, renewal review, and claims analysis.
Cell imbalance is the most common cause of BESS underperformance. It appears at virtually every site. The BMS cannot detect it in LFP systems. And it cascades predictably toward the claims on your desk.
Your pricing models use manufacturer specs and limited loss history. SynthGrid provides the asset-specific field data that changes underwriting from guesswork to measurement.
Why this data doesn't exist elsewhere. Battery analytics platforms analyze operator-provided BMS data. That's useful for operations. For claims validation and underwriting, you need data cross-referenced against sources the operator doesn't control. SynthGrid reads from the grid meter independently.
What changes at renewal. At inception, pricing rests on manufacturer specs and limited loss history. At renewal, 12 months of independent operating data can be available: actual degradation rate, thermal event log, operating envelope compliance history. The renewal conversation shifts from assumption to documented field evidence - and premium adjustments can reflect what the asset actually did, not what the datasheet said it would.
Multiple engagement models depending on where you are in the underwriting lifecycle.
Independent monitoring can strengthen both underwriting review and subsequent claims analysis.
Renewable energy insurance provides a precedent for incorporating operational analytics into risk assessment. Battery storage needs performance evidence suited to its own operating conditions and failure modes.
Vistra Moss Landing. Fourth fire. Entire book value written off.
Powin Chapter 11. 11 GWh of warranties became unsecured claims.
ERCOT ancillary revenue collapse. $149/kWh (2023) to $17/kWh (2025).
These incidents illustrate why insurers need reliable operating evidence during underwriting and claims review.
