WECC Criterion INT-021-WECC-CRT-2.1 A. Introduction 1. Title: WECC Interchange Tool (WIT) Checkout Confirmation 2. Number: INT-021-WECC-CRT-2.1 3. Purpose: To provide WECC Balancing Authorities with an auditable means of confirming Net Scheduled Interchange (NSI) and Net Actual Interchange (NAI). The WECC Interchange Tool (WIT) 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. Functional Entities: 4.1.1. Balancing Authority 5. Effective Date: January 1, 2016 WESTERN ELECTRICITY COORDINATING COUNCIL 155 North 400 West, Suite 200 Salt Lake City, Utah 84103-1114
INT-021-WECC-CRT-2.1 WECC Interchange Tool (WIT) Checkout Confirmation Page 2 of 6 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. 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 no later than the end of the current hour for the last hour in which the energy flowed or within a mutually agreed time frame if mutually agreed to changes arise. 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, as required in WR3. Evidence may include but is not limited to the data submittal audit log provided by the WIT, or its successor.

In WM2 and WM3, Interchange Authority was replaced with the proper term Interchange Coordinator as approved under the NERC Functional Model, Version 5. 1.3 January 16, 2013 Errata The term Western in the Title was corrected to WECC. The Number was corrected from the project number of WECC-0064 to the document number INT-021-WECC- RBP-1.3. Fn 1 was added to explain the Effective Dates. The document was conformed to a new template. 1.3 June 25, 2014 WECC Board of Directors changed designation from RBP to CRT Designation change 2 September 15, 2015 WECC Board of Directors Approved Developed as WECC-0108. Changes to the scheduling standardization methodology 2.1 January 28, 2016 Errata A period was added to the end of the last sentence of WM2. In the Rationale section: 1) the phrase This Criterion was replaced with the phrase This document, 2) the phrase For purposes of INT-021-WECC-CRT-2 has been replaced with For purposes of this document. Both changes were made to keep the document current as document titles and categories fluctuate. 2.1 April 1, 2016 No Change Converted to new template Under review as WECC-0118. March 2016.

If Rationale Boxes were used during the development of this project, the content of those boxes appears below. This document is in support of BAL-006-2, Inadvertent Interchange. For purposes of this document, 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.
