In W M2 and WM3, Interchange Authority was replaced with the proper term Interchange Coordinator, approved under the NERC Functional Model, Version 5. 1.3 1/16/2013 Errata Initial Initial The term “Western” in the Title was corrected to “WECC.” The “Number” was corrected from the project number of WECC-0064 to document number INT-021WECC-RBP-1.3.

Board Developed as WECC-0108; Previously WECC-00064 Page 4 WECC Interchange Tool (WIT) Checkout Confirmation INT-021-WECC-CRT-2 Overview Currently, there is no single uniform process for scheduling and checkout between Balancing Authorities (BAs) using the WECC Interchange Tool (WIT). This Standards Authorization Request (SAR) would clarify that process by modifying INT021-WECC-CRT-1.3, WECC Interchange Tool (WIT) Checkout Confirmation, a WECC Regional Criterion (CRT). Implementation Plan The drafting team does not foresee any concerns with implementing the document as proposed as of the first day of the second quarter following WECC Board of Director approval. The document as proposed: 1) requires no new training, 2) simplifies existing processes, and 3) should result in a streamlined procedure. Finally, there are no contemplated changes to the WECC Interchange Tool software. Definitions of Terms Used in the Standard There are no new defined terms proposed. For clarification only, the use of the term “common” is explained in the Guidance section of this document. Formatting This document will be reformatted after final disposition. Developed as WECC-0108; Previously WECC-00064 Page 5 WECC Interchange Tool (WIT) Checkout Confirmation INT-021-WECC-CRT-2 A. Introduction 1. Title: WECC Interchange Tool (WIT) Checkout Confirmation WECC Regional Criterion 2. Number: INT-021-WECC-CRT-2 3. Purpose: To provide W ECC Balancing Authorities with an auditable means of confirming Net Scheduled Interchange (NSI) and Net Actual Interchange (NAI). The W ECC Interchange Tool (W IT) or successor electronic confirmation tool will serve as the primary means for confirmation and will be treated as the final record of NSI and NAI under normal operating conditions. 4. Applicability: 4.1. Balancing Authority 5. Effective Date: The first day of the second quarter after approval by the WECC Board of Directors. B. Requirements and Measures WR1. Each Balancing Authority shall use the WECC Interchange Tool (WIT), or its successor, as the primary means to confirm common Net Scheduled Interchange (NSI) and Net Actual Interchange (NAI), except when the tool is not available. WM1. Each Balancing Authority will have evidence that it used the WIT, or its successor, as the Balancing Authority’s primary means of common NSI and NAI confirmation, except when the tool is not available, as required in Requirement WR1. Developed as WECC-0108; Previously WECC-00064 Page 6 WECC Interchange Tool (WIT) Checkout Confirmation INT-021-WECC-CRT-2 WR2. Each Balancing Authority shall confirm its common NSI with each Adjacent Balancing Authority at the following time periods: 1) Prior to implementing the energy profile of the aggregated Confirmed Interchange (and) 2) After the operating hour. WM2. Each Balancing Authority will have evidence that it confirmed its common NSI with each Adjacent Balancing Authority at the times required in Requirement WR2. Evidence may include but is not limited to the confirmation audit log provided by the WIT or its successor. Bullet 2 is not to be interpreted to conflict with the allowance of after-the-fact settlement WR3. Each Balancing Authority shall provide hourly NAI data, equal in magnitude and opposite in sign or direction, to the electronic confirmation tool for each of its Adjacent Balancing Authorities before the start of the next clock hour and on mutually agreed to changes. WM3. Each Balancing Authority will have evidence that hourly NAI data was submitted to the electronic confirmation tool for each of its Adjacent Balancing Authorities before the start of the next clock hour and on mutually agreed to changes, as required in WR3. Evidence may include but is not limited to the data submittal audit log provided by the WIT, or its successor. Developed as WECC-0108; Previously WECC-00064 Page 7 WECC Interchange Tool (WIT) Checkout Confirmation INT-021-WECC-CRT-2 Guidance Section This Criterion is in support of BAL-006-2, Inadvertent Interchange. For purposes of INT-021-WECC-CRT-2, the word common means that Net Scheduled Interchange (NSI) or Net Actual Interchange (NAI) between only two Adjacent Balancing Authorities (BA) as opposed to the aggregate NSI or NAI with all BAs.
