Illinois CPWG standards and version control process


This Change Control process accomplishes the objective of an established Change Control
process that accommodates changes within the Illinois Communications Protocol Working
Group (CPWG) standards.

Illinois CPWG standards may be expanded and modified to accommodate market or regulatory
requirements on an ongoing basis. Change Control provides market participants a process to
modify, test and implement changes in an efficient, effective, timely, and well-coordinated
manner. This Change Control document provides the process by which changes to the standards
may be discussed, reviewed, accepted and implemented.

The Illinois CPWG with support from the Illinois Commerce Commission (ICC) maintains,
publishes, and posts the standards and the ongoing modifications/enhancements to these
standards on the Illinois CPWG website.

The Illinois CPWG notifies each market participant – via postings to the Illinois CPWG List
Server – of anticipated modifications or enhancements and timing.

A consolidated new release of the Illinois CPWG standards is published electronically as needed.
The Illinois CPWG will ensure any approved Change Requests are included in a redlined
document which will be updated and posted to the Illinois CPWG website within one month of
approval. It is the intent of the ICC and Illinois CPWG to have any new request comply with the
North American Energy Standards Board (NAESB) guidelines as the industry and the data
standards evolve.

When new modifications and/or enhancements are introduced to the group, the proponent of said
modification/enhancement should strive to build consensus for the change among all Illinois
CPWG participants.
