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?

ISAS Liaison Report
Interchange Authority Discussion ISAS voted on the following motion:
“WECC provides its membership the IA functionality through the WIT and is the contract holder of the WIT. As a member driven organization, we recommend WECC register as the Interchange Authority.”
Motion passed: 34-0-3 Basis: NERC Functional Model, Version
3, technical document, page 39.
