FOR BESS OPERATORS AND ASSET OWNERS

The numbers don't match. Find out which one is right.

A documented 350 MWh case study found 11% of capacity stranded by imbalance. When BMS records and grid-side delivery disagree, financing and warranty decisions are exposed. SynthGrid provides an independent performance record.

YOUR SITUATION

Where are you right now?

YOUR BATTERY UNDERPERFORMS BUT YOU DON'T KNOW WHY
11% of capacity stranded. Is it degradation or imbalance?

The weakest cell dictates your string capacity. Energy between the strongest and weakest is stranded - invisible to the BMS, missing from your revenue. Degradation is irreversible and warranty-claimable. Imbalance is recoverable through rebalancing. A capacity test measures both together and can't tell you which. Independent measurement distinguishes the two - the difference between a $5-10M augmentation and a fraction of that cost.

APPROACHING A DISPUTE?
Get an independent assessment before you commit.

A forensic pre-check before you commit to litigation. Independent degradation analysis, dispatch history review, and warranty compliance assessment from your existing BMS and meter data.

MANUFACTURER WENT BANKRUPT?
11 GWh of deployed BESS just lost warranty coverage.

Independent performance documentation for bankruptcy claims, replacement vendor evaluation, and lender reporting. Your data shouldn't disappear when your manufacturer does.

LENDER ASKING QUESTIONS?
ERCOT revenue collapsed 84%. Is it the asset or the market?

Average BESS revenue fell from $149/kWh (2023) to $17/kWh (2025). Most operators below 2.2% profitability. Independent assessment separates market problems from asset problems. When your lender asks why revenue is down, you need data that shows your battery performed to spec even when the market didn't.

YOUR CAPACITY TEST DOESN'T MATCH OPERATIONS
Suppliers "prepare" systems before warranty tests. The results don't reflect reality.

Before a capacity test, the supplier rebalances modules and recalibrates SOC - removing the very conditions that cause underperformance in normal operations. Test regimes include long rest periods and reduced rates that don't reflect field conditions. A capacity test tells you what the battery can do on its best day. SynthGrid tells you what it does every day.

CLAIMING THE ITC?
Tax-credit reviews depend on defensible records.

Some Clean Technology ITC claims may be selected for further CRA review. Clean technology property may also face recapture consequences for events occurring in the acquisition year or any of the preceding 10 calendar years. Traceable performance records help your team assemble technical support when a claim or compliance obligation is reviewed.

Program rules: Canadian recapture and U.S. supply-chain eligibility requirements are distinct and require specialist review.

RUNNING LFP? THE PROBLEM IS WORSE THAN YOU THINK
LFP's flat voltage curve hides capacity differences of 15% or more.

LFP operates across a 10mV voltage plateau where SOC ranges from 20% to 80%. A 10mV measurement error causes +/-15% SOC estimation error - vs. +/-3% for NMC. Two racks can show identical voltage but have wildly different actual capacity. Passive balancing, designed for small-format cells, fails at grid scale. Your BMS literally cannot see the problem.

HOW IT WORKS

Four steps. No disruption.

STEP 1
1. Connect
Reads telemetry from the utility grid meter and your BMS. Read-only. No control, no commands, no interference.
STEP 2
2. Verify
Grid-side and asset-side data cross-referenced through a physics-based validation pipeline. Discrepancies flagged. Every check documented and reproducible.
STEP 3
3. Sign
Each attestation record is cryptographically signed. Neither side can alter a record after the fact.
STEP 4
4. Report
Verified data delivered monthly, quarterly, and annually to match your lender's cadence. Dashboard access is continuous. Degradation curves. Capacity trending. Revenue verification. Remaining economic life.
Asset scope: Utility-scale and ISO-connected BESS. Behind-the-meter assets (peak shaving, TOU arbitrage) supported with our expanded validation engine. Contact us for your specific configuration.
THE DELIVERABLE

What you receive.

Your EnergyPassport. Built to be handed to a warranty counsel, a credit committee, or a government auditor without further explanation.

USE CASES

Six ways EnergyPassport pays for itself.

WARRANTY PROTECTION
Continuous envelope compliance monitoring
Temperature, SOC, C-rate, depth of discharge, cycle count. All tracked against your specific warranty terms, continuously, with independent data. When a scheduling coordinator cycles your battery beyond warranty limits, SynthGrid documents that the exceedance was caused by dispatch, not by you.
Real-time alerts when dispatch approaches warranty limits
On-demand signed data exports for claims
Dispatch-control documentation for arbitration
Why independent data matters: The manufacturer controls the BMS. In a warranty dispute, the only performance data available is data provided by the party you're filing against. SynthGrid's dual-telemetry cross-check produces records that neither side controls.
NEW PROJECT FINANCING
A verification commitment in your credit package
A one-page Verification Commitment Letter goes in your credit package alongside the IE report. Your lender prices the loan knowing continuous verification is locked in for the debt tenor. Continuous warranty monitoring with on-demand PDF reports and data exports included.
Pre-close: Commitment letter in credit file
At COD: Baseline verification report
Post-close: Ongoing reports to lender
Build-and-refinance? Most BESS projects are equity-funded, then refinanced after 12-18 months. 72% of BESS failures occur in those first two years (EPRI 3002030360, 2024). Include a VSA at the equity stage and the refinancing data is verified from Day 1.
For multi-site developers: every verified site de-risks the next financing.
DISPUTE EVIDENCE
Warranty Arbitration
Installation, cells, or BMS software? Neutral performance data resolves the finger-pointing. Designed for adversarial proceedings.

REFINANCING
Unlock Trapped Capital
Baseline report from your existing BMS logs in 60 days. Gives your lender the performance verification they need to unlock refinancing against an operating asset.
Verification often bundled by your OEM or distributor in the project budget. Contact us to learn more.
DEGRADATION INTELLIGENCE
Know When to Budget for Augmentation
Chemistry-specific degradation tracking against your warranted curve. Independent capacity trending tells you exactly when cell replacement is needed - not when the OEM says it is. Anomaly detection catches thermal excursions and efficiency drops early.
Augmentation planning based on verified data, not manufacturer projections
COUNTERPARTY VIEW
See What Your Lender Sees Right Now
Your lender, insurer, and government program officer each see your asset through their own lens. EnergyPassport gives you the same view they get - before they call. Catch a covenant trending toward breach. Fix a data gap before audit season. Respond to flags before they become conversations.
Zero competitors offer operator-side counterparty view controls
INSURANCE
Stop Paying 2x Your Pro Forma Premium
Your insurer is quoting high because they can't independently verify your asset's health. BESS premiums have roughly doubled in two years - insurers are losing money and pricing blind. SynthGrid provides the independent performance record your insurer needs to price accurately. Operators with verified data negotiate better terms.

The SynthGrid Position
  1. 01

    Data independence is the product. We cross-reference against sources you don't control - the protective relay at the POI, grid operator records. Every record is auditable end-to-end. Third-party or nothing.

  2. 02

    Continuous beats snapshot. A PDF at closing is fiction by month three.

  3. 03

    Every record is signed. Tamper-evidence by default, not by agreement.

  4. 04

    The battery becomes the instrument. Verified performance protects every decision you make.

  • Optimizes dispatch and maintenance
  • Internal operational tool
  • Operator's own data, operator's own analysis
INDEPENDENT EVIDENCE
  • Cross-references BMS against grid meter
  • Produces signed, tamper-evident records
  • Supports dispute and audit review
  • Third-party data, third-party opinion
ENGAGEMENT OPTIONS

Continuous monitoring. Three ways to access the data.

Dashboard access, on-demand PDF reports, and API feeds. The data is there before you need it.
