Interchange Scheduling and Coordination

1.a Interchange Scheduling and Coordination is one of the 31 knowledge areas in the NERC System Operator Certification content outlines.

The NERC Glossary defines the TLR Log as the report required after every TLR Level 2 or higher. The NERC Interchange Distribution Calculator prepares it, the issuing Reliability Coordinator reviews and approves it, and it is then filed in a public area of the NERC web site.

  1. A. Native Balancing Authority
  2. B. Attaining Balancing Authority
  3. C. Intermediate Balancing Authority
  4. D. Sending Balancing Authority
Show the answer

Answer B Attaining Balancing Authority

The NERC Glossary defines the Attaining Balancing Authority as the one bringing generation or load into its effective control boundaries through a Dynamic Transfer, which is Balancing Authority N here. Balancing Authority M, which gives the resource up from its boundaries, is the Native Balancing Authority, and an Intermediate Balancing Authority is a different idea again: one sitting on the scheduling path of an Interchange Transaction.
