Same battery. Same days. More margin.
An ERCOT battery already in commercial operation. We rebuilt its instruction path and ran both its own dispatch and a fixed Metis candidate through the same execution and accounting boundary.
+$585k
additional after-variable-cost energy margin across 107 operating days — about $55 per MW-day on a 100 MW / 200 MWh asset
Public-data replay
Every sensitivity in the registered envelope came back positive, from +$429k to +$619k.
What was already operating.
The benchmark is the asset's disclosed SCED Base Point path — the instructions it actually followed, not a reconstruction of the bid curve behind them. That path already carries the operator's day-ahead position and their ancillary obligations, so beating it means finding value inside the schedule they were already committed to. Settlement-point RT prices gave both paths the same execution and accounting boundary.

How the replay candidate was built.
- 01
Reconstruct
Align public Base Points, settlement-point RT prices, disclosed DAM ancillary-service awards, and a registered public physical envelope.
- 02
Plan
Combine the D-1 CDR path, Chronos-2 price fans, and decision-time-valid two-hour recourse. The inherited recipe was not retuned on this asset.
- 03
Recommend
Recommend charge or discharge when forecast value cleared wear and registered constraints, then re-solve as new price information became available.
Why the result held.
The central result survived the tests most likely to expose a replay that depends on a few favorable intervals.
Modeled energy-margin replay. Awarded ancillary capacity was preserved, but ancillary revenue and settled P&L were not scored.
- Positive across the full registered scenario envelope: +$429k to +$619k.
- Still +$236k after deleting the ten strongest days.
- Still +$428k with terminal inventory marks removed.
