09/10/2009 ROS To grant OGRR235 Urgent status Passed


Status: Approved
Date Posted: Sep 3, 2009
Sponsor: ERCOT
Urgent: Yes
Sections: 2.2.2, 3.1.6, 2.4.1, 4.3.1
Description: This Operating Guide Revision Request (OGRR) replaces the acronym Total Transfer Capability (TTC) with Total Transmission Capacity (TTC), as defined in Protocol Section 2.2.
Reason: Total Transfer Capability, as defined by NERC, does not apply to the ERCOT Region since there is only one transmission system. Total Transmission Capacity is the comparable ERCOT terminology, but the two acronyms are used interchangeably throughout the ERCOT Protocols. This may cause ERCOT to appear to be out of compliance with the NERC Reliability Standards when compliance has actually been achieved or the requirement is not applicable to ERCOT.
