description	Establish historical electricity tariff evidence and label verified, candidate, and illustrative cost models correctly.

Utility tariff evidence

Goal

Model electricity cost without confusing an illustrative tariff with the building's actual historical billing arrangement.

Procedure

1. Identify service territory and measured-data dates.
2. Find archived tariff sheets effective during those dates.
3. Prove the customer's actual rate assignment from a bill, account record, procurement record or equivalent evidence before calling it verified.
4. Encode seasons, TOU windows, holidays, billing demand, ratchets/floors and adjustments only when supported.
5. Preserve tariff source/version and effective dates.
6. Use the same timezone and interval convention as the measured meter.

Required labels

• VERIFIED: account, meter boundary, source document, and effective period are proven.
• CANDIDATE: authentic schedule/scenario, but account-period binding is not proven.
• ILLUSTRATIVE: synthetic research scenario.

Never present candidate or illustrative cost as a reconstructed utility invoice.
