NOGRR239  WAN Data Protection Responsibilities

This Nodal Operating Guide Revision Request (NOGRR) adds language to Section 7.1 to delineate the responsibilities of providing security for data transmitted between ERCOT, Qualified Scheduling Entities (QSEs), and Transmission Operators (TOs) as follows: • Establishes the “handoff” of data transmitted between ERCOT and QSEs/TOs to be at the ERCOT-managed router located at each WAN Participant’s WAN demarcation point; • Establishes that ERCOT will manage data encryption keys for data transmitted between ERCOT and the ERCOT-managed router located at each WAN Participant’s WAN demarcation point; and • Establishes that QSEs and TOs are responsible for any data protection downstream of the ERCOT-managed router located at each WAN Participant’s WAN demarcation point.
