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.

Process to be followed

  • The interested party creates a Change Request and sends it to the Change Control Manager at CPWGChangeRequest@ameren.com  at least 5 days in advance of the scheduled call on which it is to be discussed. The Change Control form is available on the Illinois CPWG website.
  • The request will be reviewed by the Change Control Manager to determine if the request is valid and clearly stated. For example, an invalid request would be one that involves changing a Delivery Services Provider(s) (DSP) business practice. This request would be sent back to the requestor with instructions to deal directly with the DSP. Or the request may be valid but not stated clearly or with enough detail. In this case the Change Control Manager may contact the requestor to ask clarifying questions. Following this Conversation, the Change Control Manager may modify the request before distributing it to the entire group.
  • Once the Change Control Manager has reviewed the request and determined that the request is valid, the request will be posted to the Illinois CPWG list server.
  • The Change Request will be discussed at the next scheduled conference call or meeting.
  • Participants should strive to either approve or cancel a Change Request within 1-2 meetings.
  • If the Change Request is approved, a timeline should be established as to when the Change Request should be implemented. This timeline should be a consensus of the market participants.
  • Each implementation guide affected by the change should be updated as a redlined document and made available to all market participants by posting to the Illinois CPWGwebsite within 30 days of approval.
  • The Illinois CPWG will determine the level of testing needed prior to the agreed upon implementation date.
  • Unresolved issues relating to proposed changes will be forwarded by the Change Control Manager to the ICC for resolution.
