ISAS Liaison Report
Interchange Authority Discussion OC requested ISAS to discuss and make a
recommendation on identifying the IA for the WECC.
Discussion IA standards are vague White paper developed describe the IA in the
WECC. WECC banded together to create a common authority service - WIT
Who registers as IA in the WECC? What happens if the WIT fails to distribute
arranged interchange? Who pays penalties?
