Allocation quality

How the energy volume was arrived at, in ascending order of trust. When one settlement period carries several records, prefer the highest quality.

Available allocation qualities

• provisional — A placeholder the sender intends to replace.

• estimated — Substituted because no reading was available: profiled, interpolated, or copied from a comparable period. Expect it to be superseded.

• calculated — Derived by a defined computation rather than read.

• measured — Read off the meter.
