Energy · Battery owners
How much of the available value did your optimiser capture?
Revenue from a traded battery mixes the optimiser's skill with the site, the grid connection and the market. A good month can be the market, and a poor one can be the grid connection.
The owner-side assessment separates them. It measures how much of the available value the optimiser captured, attributes the shortfall to its sources, and states the uncertainty on each number.
IllustrationThe worked example uses simulated continental data, not a live GB battery, so this page quotes no figure from it.
EvidenceMy published work asks the same kind of question of a forecast. Around the German day-ahead load forecast, a 90% band built the usual way covered 84.8% of quarter-hours [82.3%, 87.1%] over 336 scored days.

The 2 offers answer different questions. The assessment asks how much value was captured. The band audit asks whether the optimiser's stated confidence in its forecasts held, and each dispatch rests on that confidence.

The Band Checker runs the first 2 sections of the band audit in your browser, on your own CSV or on the bundled DE-LU sample. There is no battery sample yet.
First step
Write to matthew@mtanti.com for the worked example, or with one paragraph describing the asset and its optimisation contract. A standard mutual NDA comes before any data moves, and your data is deleted on delivery and never used elsewhere.
What this does not support
The owner-side assessment has not yet been run on a live battery, and the worked example is simulated data from continental markets. It therefore supports no claim about any real asset, any optimiser or the GB market. The published figure concerns a German load forecast, not a price forecast and not a battery. Nothing on this page ranks optimisers.
