8 WECC was asked a question about what it means to check a checkbox in WIT. Does it mean that: BA home scheduling system agrees with the WIT value (INT- 021-WECC-CRT-1 WR2), or BA value matches neighbouring BAs value (BAL-006 R4.1), or NAI specific, confirms BA has sent its values to WIT (INT- 021-WECC-CRT-1 WR4) WECC Unofficial Response: Entities should use WIT to comply with NERC standards, which points to middle interpretation ESWG Update
