The purpose of the demand reset is to capture peak demand values and the times at which those val-
ues were recorded since the last time the reset procedure was executed. Scheduled Demand Resets 
may be performed based on Billing Cycle membership, or based on Virtual Addressing Group 
membership. Only endpoints in Normal status will be sent the scheduled Demand Reset command.

A Demand Reset can be set up as a Scheduled Read in Command Center.   Once the demand reset 
date is scheduled, X days prior to the demand reset date Command Center will send 2 scheduled 
tasks to the endpoints included in the demand reset. The value X is a configurable System Setting in 
Command Center called the Scheduled Demand Reset Window to send Commands and must be 
between 2-21 days. The two scheduled tasks sent to the endpoints at this time are:

 A temporary task to perform the Demand Reset (snapshot) 

A task to read the Demand Reset data (from S25 table) and transmit it to Command Center. 

Then at 12:00 AM on the day the demand reset is scheduled, for each endpoint included in the 
demand reset:

The meter creates a snapshot

The endpoint radio reads and transmits the Demand Reset data

There are a number of business decisions that the utility must make in regards to how the Demand 
Reset process is managed. These include:

1. Will demand resets be performed based on Billing Cycle or Virtual Addressing Group?

2. What are the Demand Reset dates?

3. When should the Demand Reset scheduled tasks be sent to the meters?

4. What does the utility do if the Demand Reset fails?

Basing Demand Resets on either Billing Cycle Membership or Virtual Addressing Group member-
ship will have different consequences when it comes to making changes in group membership:
