Estimation routines

Average Daily Load replaces all intervals in the day with an equal value, creating a flat load for the day. This routine divides the average daily load by the number of intervals in the 24-hour period to calculate the equal interval value. For more information, see Average daily load estimation.

Check Meter replaces intervals marked as ESTNEEDED (Estimation Needed) with the corresponding intervals from the designated reference channel on the same service point. For more information, see Check meter estimation.

Final Estimation ensures that no other estimation routine replaces an estimated read that has a status of FINALESTIMATE. For more information, see Final estimation

The Historical estimation routine calculates average daily load shapes using data from historical reference days. IEE derives interval-by-interval averages from valid intervals from the three nearest days of the same or like day of the week. For more information, see Historical estimation.

Linear Interpolation resolves small gaps by creating estimated interval values between two valid interval reads. This routine creates readings that fill the gap with no peaks or valleys. For more information, see Linear interpolation.

Load Profiling replaces interval values that need estimation with interval values from the defined reference service point channel for the same time period. For more information, see Load profile estimation.

Load Shaping creates and estimates interval reads from a Load Shape reference, with multiple scaling options to adjust the reads. For more information, see Load Shaping estimation.

Multi-week average algorithmic estimation finds and averages all valid reference intervals for the number of reference weeks selected. Valid reference intervals have the same day of week and date and time stamp as the intervals that need estimation. For more information, see Multi-week average estimation.

Numerical replacement estimation replaces invalid data with a user-defined number. For more information, see Numerical replacement estimation.

Two-Week Like Day Historical replaces intervals that need estimation with data from like-days. IEE selects these like days from either the two weeks immediately preceding the intervals to estimate or from the same two weeks from the previous calendar year. For more information, see Two week like-day historical estimation.

Average Recent Load Projection estimates missing register reads. For more information, see Average recent load projection.

Copy Forward Register performs estimation on register reads that have failed validation and are marked with Estimation Needed status. The routine estimates the register by finding the most recent actual register and copying it forward. The estimated read is marked with Estimated status. For more information, see Copy forward register.
