Current Configuration WEQ 2019 Annual Plan Item 3a Current Configuration NAESB Standard WEQ-001 currently requires a Transmission Provider to register certain OASIS data elements in the EIR. NAESB e-Tag specifications require registration of Sources and Sinks data elements in OASIS. 10/15/2019

WEQ 2019 Annual Plan Item 3a The Challenge Establishment of a requirement to automatically update a Provider’s OASIS data model based on changes to the EIR may introduce significant challenges in all downstream systems dependent on the OASIS data model.
