  1. Order 693 Compliance LTTIWG Conference Call December 14, 2007

  2. Order 693 Paragraph 1051 The Commission directs the ERO, through the Reliability Standard development process, to modify FAC-012-1 and any other appropriate Reliability Standards to assure consistency in the determination of TTC/TFC for services provided under the pro forma OATT, and requires that those processes be the same as those used in operation and planning for native load and reliability assessment studies. Changes to the process of calculating TTC are appropriate if implementation is coordinated with revisions to the other applicable operating or planning standards. We acknowledge that reliability regions have historically calculated transfer capability using different approaches, and we agree that regional differences should be respected.336 However, as already discussed above regarding ATC, TTC requirements will be determined in the ERO Reliability Standards development process, and any request for a regional difference from the Reliability Standards must take place through the ERO process. 336 For example, WECC has a documented open process for establishing TTC for the Western Interconnection.

  3. Ralph Honeycutt Questions • What changes or modifications has the ICT contemplated to comply with paragraph 1051 of Order 693, which requires “consistency in the determination of TTC/TFC for services provided under the pro-forma OATT, and requires that those processes be the same as those used in operation and planning for native load and reliability assessment studies.”? [emphasis added]

  4. Ralph Honeycutt Questions • I do not recall this specific paragraph being specifically discussed as to what changes the ICT and Entergy are considering.  Perhaps this issue needs to be discussed at the next LTTIWG/NTTIWG meeting.  It seems that any changes may need to be reflected in the tariff.

  5. ICT / Entergy Response We do not believe any changes currently are required.  However, we are awaiting NERC's resolution of this requirement in FAC-012-1 and related standards, at which point Entergy and the ICT will review the current Entergy processes to assure consistency with the requirements that are put in place.
