Subject:  Reminder: CAISO e-Tag Requirements - Contingency Reserve Tracking Conference Call on 11/15/07



Summary:  Reminder - The CAISO will conduct a conference call on November 15, 2007 at 1:00 p.m. to discuss the NERC e-Tag changes for energy imports and exports required as a result of two new WECC Business Practice Standards.  The CAISO has posted a white paper to its website for Stakeholder review.



Main Text:  This is a reminder that the California ISO (CAISO) will conduct a conference call on Thursday, November 15, 2007 to discuss its e-Tag requirements for energy imports without reserves, necessary as a result of two new Western Electricity Coordinating Council (WECC) Business Practice Standards, INT-BPS-WECC0004 (Specific Energy Product Codes) and INT-BPS-WECC0014 (Contingency Reserve Tracking).  These new WECC standards are planned to be effective concurrent with the implementation of North American Electric Reliability Council (NERC) e-Tag Version 1.8.


The CAISO informs all Scheduling Coordinators and their Purchasing/Selling Entities (PSEs) about its requirement for tagging energy imports, which do not carry reserves, into the CAISO as the sink Balancing Authority (BA).  Firm imports without reserves, scheduled into the CAISO, must continue to use the WECC Energy Product Code G-FC (Unit Contingent Imports) on the NERC e-Tag.  The WECC G-FC energy product code is the CAISO’s primary determinant for its procurement of the required contingency reserves, as the sink BA, to meet these WECC and NERC standards.


Stakeholders can review the CAISO e-Tag Requirements – Contingency Reserve Tracking White Paper located on the CAISO website at
