Reliability Standards

Reliability Coordination - Transmission Loading Relief (Project 2006-08) 


Registered Ballot Body | Related Files | Reliability Standards Home Page | Drafting Team Rosters

Status
 The TLR Drafting Team is considering the comments received from the posting of the first draft of the Transmission Loading Relief Reference Manual.

Approved for adoption by the NERC Board of Trustees on October 23, 2007. 

Purpose/Industry Need
In August 2004, NERC and NAESB agreed to immediately begin a joint effort to update the Eastern Interconnection TLR Procedure, as reflected in Attachment 1 to reliability standard IRO-006-0, to divide the reliability requirements and business practices, and to incorporate other necessary improvements to the TLR procedure.  In December 2004 NERC and NAESB formed the joint TLR Subcommittee to clarify and focus Attachment 1 to NERC reliability standard IRO-006-0 on the TLR requirements that are necessary for reliability, as distinguished from those TLR requirements that are business practices.
