B B O O N N N N E E V V I I L L L L E E P P O O W W E E R R A A D D M M I I N N I I S S T T R R A A T T I I O O N N Guidelines for Load Forecast Principles Guiding changes Communicate with us as soon as possible so your forecaster can review your additional information. This year we are a bit more flexible due to uncertainties around COVID-19. More likely to accept reasonable changes with identifiable COVID-19 links. Amounts of change are likely vary based on local economies. Amounts of change will likely vary up the maximum reduction we have seen identified worldwide. Only impacts customers with a non-zero AHWM . Continue to want to avoid subjective bias in results Make changes with a clearly identifiable cause and effect. Temporarily suspending some of the change criteria, those tied to modeling statistics and prior model performance. Incorporate highly probably information on new load additions. Include new loads/projects that have higher than 70% probability of occurring. Incorporate highly probably information on new load additions.
