Register Reads and Interval data, the algorithm confirms that the sum of the intervals matches
the register read delta for the same time period.
The Validation, Editing, and Estimation (VEE) engine within the MDM validates energy
consumption according to a utility’s data quality requirements and provides estimates for the
inevitable missing and incorrect data that comes from meter data collection systems. The VEE
engine continuously reviews and repairs problematic data. VEE fills in gaps, flags where
corrections have been made, and triggers manual review where the data cannot be repaired
using standardized logic.
The MDM's standard validation rules are included in validation sets. These rules use custom
logic built into the MDM and will allow FortisBC to set some of the parameters needed to run the
rules. An example parameter-based rule is one that checks for a high limit. For this rule,
FortisBC would specify the high-end thresholds for the specific limit to check.
Some examples of validation rules include:
• Gap Check;
• Historical Max Usage Percentage Difference;
• Interval Tolerance Check;
• Load Factor High & Low Limits;
• Max & Min Zero Intervals;
• Spike Tolerance Percentage Difference;
• Overflow Check;
• Register High Limit;
• Register Low Limit;
• Rollover Check;
• Usage On Inactive Meter; and
• Zero Usage On Active Meter
