Explicit intervals. Verifiable energy.

Each row describes an interval boundary and energy quantity. Timestamps include a UTC offset so daylight-saving transitions remain auditable.

Rules

Supported interval lengths are 5, 15 and 30 minutes.
Energy values are finite, non-negative kWh.
Intervals use one resolution, remain ordered and do not overlap.
The maximum input is 5 MiB, 10,000 intervals and 32 elapsed days.
quality is actual, estimated or substituted.

Structured JSON can declare Grid and Controlled Load Import/Export channels explicitly. It normalizes to the same Energy Bundle as equivalent CSV.
