Methodologies and load

1. Zone 1001 Load, Loss, UFE

2. Zone 1001 Net System Load Shape / Unmetered Night Profile / Unmetered Flat Profile

3. Net System Load
Load settlement systems must have the capability to accommodate profiling classes split from NSLS, based on load research or deemed methods. The net system load (NSL) shall be calculated for each hour as:

(Total system load) – [(Sum of interval metered customers) + (Sum of deemed loads) + (Sum of loads for load-research-based profiled classes) + (Sum of known losses)]

Net System Load Shape
NSLS for a period is calculated by dividing the hourly NSL by the sum over hours in the period of the NSL.

4. Loss Factors
Distribution losses are calculated as a percentage of total energy consumption. These loss values represent the energy lost while delivering electricity through the distribution system, from the substation to the customer’s meter.
