| Settlement ID -1030 | EPCOR |
| Settlement ID -1060 | Crowsnest Pass |
| Settlement ID -1100 | Cardston |
| Settlement Interval | The settlement interval is the time increment at which distinct load estimates are calculated by load settlement systems and load amounts are settled financially by the Pool. |
| Settlement Ready Data | Data that is ready for use in settlement. Data shall be validated, estimated and edited as outlined in the standards, and aggregated or totalized to measurement point data as per the Measurement Point Definition records. |
| Settlement Run Date | Date and time settlement was initiated. This date does not indicate which date was used by the settlement run. The standard Date format has been defined as: YYYYMMDDHHMISS. |
| Settlement System | A settlement system is a computer system and associated operations and interfaces used to determine the load responsibility at each unit of the settlement interval, for each retail supplier operating within the settlement zone. |
| Settlement Timing | Settlement timing is the frequency at which load settlement is calculated and reported to the Pool and to retailers. |
| Settlement Type | The settlement type is the time interval at which distinct load estimates are calculated by load settlement systems and load amounts are settled financially by the Pool: I - Initial Daily Settlement; M - Initial Monthly Settlement; R - Reconciliation Settlement; F - Final Settlement. |

| Site Type Chart | The Site Type Chart differentiates total load into size components. TA sites represent the very large sites connected to the transmission system. TA sites are on interval meters and are not charged for Loss or UFE. DIM load profile represents larger sites (over 500 kW) that have interval meters. DIM sites have lower loss factors and the hourly profile is determined by physical consumption. A large DIM load profile means there are few large sites making up most of your load, hourly profile is controllable and Loss is less significant. A large DCM load profile means you have many small sites, profile is fixed and Loss is more significant. |
