back-stop scheduling process that protects the reliability of the grid during Interchange-software failure that prevents the distribution of e-Tag information for assessment of confirmed interchange transactions, distribution of confirmed interchanged transactions, or both." To: purpose of this document is to establish a coordinated back-stop scheduling process that protects the reliability of the grid during Interchange-software failure that prevents the distribution of e-Tag information." WR3, WR7, WM7: From: "Each Balancing Authority shall maintain a duplicate copy of its aggregate Net Scheduled Interchange (NSI) as previously confirmed by the interchange software." To: "Each Balancing Authority shall maintain a duplicate copy of its aggregate Net Scheduled Interchange (NSI) as previously confirmed in the interchange software." Balancing Authorities confirm NSI within the interchange software. WM5 WM5 asks for an attestation if no failures of the interchange software were suspected. Entities are not audited on regional criteria, so keeping an attestation on file seems burdensome. BPA believes it is sufficient to keep evidence that the Balancing Authority/Purchasing-Selling Entity reported a suspected failure of the interchange software to the interchange software provider. The DT concurs with BPA and has redrafted the Purpose statement as follows: Purpose Statement The proposed change to the Purpose statement would strike the phrase, “….for assessment of confirmed interchange transactions, distribution of confirmed interchanged transactions, or both.” “By” versus “In”
