System evidence

Reported capacity and specifications

Values can describe different project phases or components. Source citations are attached to each figure so discrepancies remain visible.

Storage: .5/1.5 MW/MWH [1]

Controls and hardware

Equipment and controller details

Manufacturer and model are shown only when a source names them. Generic descriptions are not converted into guessed product assignments.

No controller or equipment model was found in the reviewed public sources. This is a disclosure gap, not evidence that the project lacks coordinated controls.
