Open Issues / Responses

• No Severity 1 or 2 defects identified in testing or training• Will there be focused ICCP-only training or a guide for SCADA-focused employees?

– All TSP users are encouraged to attend the basic training being offered

– When this training is complete ERCOT will see if there is a desire of MPs to have specialized training for SCADA assignments to build upon the basic training

• Can an MP modeler set-up new equipment, and then have another user make the ICCP assignment?

– Yes, the same TSP can have one user establish the equipment in a NOMCR, and a different user can edit the NOMCR to complete the SCADA assignments

• Can ERCOT set-up a read-only role?– By default users granted read/write privileges, upon an email request to ERCOT can grant read-only

• Operatorship vs Ownership Line assignment- Legal working on draft of NPRR• Service Level Agreement post SEM Go-Live-

– IT support 99.9% availability, 4 hour recovery

– Same business support as used for Service Requests

• Single Entry Model (SEM) Go-Live is the switchover on Aug 31, 2009 for TSP submissions of network operations model change requests

– from “Service Request” submissions via TML

– to “NOMCR” submissions via the NMMS • System of record for model changes becomes NOMCRs on 8/31//09

• System of record for Network operations Model for reliability and dispatch remains Zonal/Genesys system until Dec 2010
