WI - Phoenix and San Diego WI - Phoenix and San Diego –December 5, 2007 – E-tag 1.8 implementation.

WIT Registry and WIT Implementation Functionality highlights: Functionality highlights: –Only for BAs at this time. –Cannot create something that has not been entered into TSIN. Drop downs come from the NERC registry. –When a PSE registers a Sink or Source for a BA, the system is not designed to notify the BA individually. The BA should currently receive notification from TSIN that a new point has been registered. –Be aware that the NERC site could take quite a bit of time before the entry is valid. –Contact Mark Nielsen (project manager) at OATI with technical questions.

WIT Registry and WIT Implementation Live on May 30, Live on May 30, One known bump in the road since going to full implementation. One known bump in the road since going to full implementation. –Seven entities impacted (could not submit tags for validation). –Vendor reviewing cause.

EIWG Update Implemented more formal review, comment and voting methodology regarding e-tag issues raised to the EIWG. Implemented more formal review, comment and voting methodology regarding e-tag issues raised to the EIWG. –Review issue. –Evaluate against reliability standards. –Document findings. –Formulate resolution to entity that issue was raised against. –Vote at ISAS only if entity disagrees with recommendation.

EIWG Update Reviewed: Reviewed: –Improper Denial of an e-tag by a TP. –Unauthorized Use of Override Function in ETS (tagging software). –Improper Denial of an e-tag for non-required field. –Denial of e-tags due to software problem –Passive denial of tags

BPWG Update Rework on INT-BPS Rework on INT-BPS –Did not pass at March, 2007 OC Meeting. –Purpose: define WECC requirements in addition to NERC standards. –Prior to operating hour, dynamics not part of NSI between adjacent BAs. 60 minutes to update, 96 hours to correct. 60 minutes to update, 96 hours to correct. –Motion passed to approve modifications.
