The problem · BESS

Three blind spots that quietly destroy battery value

BESS operators see gross revenue. They rarely see what each megawatt-hour actually cost the asset — until the warranty review or the EOL test.

The degradation blind spot

€1.2M/yearun-costed on a 100 MW / 200 MWh asset

Trading desks see the gross arbitrage spread. They almost never see the cost-per-cycle the battery just paid to earn it. Net revenue after degradation is a different number entirely — and the gap compounds every dispatch decision until the next capacity test reveals it.

Warranty discovered at claim time

Years latemost violations are found during claim review

Equivalent-cycle caps, SoC dwell limits, C-rate envelopes, temperature windows — every OEM warranty bakes in a dozen conditions, none of which your monitoring tool tracks against the contract. By the time a claim fails, the stress events are years old and unrecoverable.

Dispatch is leaving money on the floor

8–15% netspread vs naive arbitrage, same prices

The right cycle at the wrong depth or temperature can wipe out the entire margin. Degradation-aware dispatch chooses which spreads to chase based on what they actually cost the asset — quietly recovering double-digit percentages of net revenue without spending a euro on CAPEX.

What we do

We instrument SoH trajectory, equivalent-cycle accounting, warranty compliance and degradation-aware dispatch on your actual operating data — and bake the evidence trail into CSRD- and EU-Battery-Regulation- ready reports. PV operators get the same treatment for soiling, fault detection and portfolio analytics.

Methodology · one real flow

From SCADA stream to priced recommendation, in one panel

Every audit follows the same loop: ingest your data, annotate the chart where money is leaking, and price the recommendation in €/day so the finance team can read it. No black-box scoring.
