Question 1 · Analysis

A Generator Operator disagrees with the reporting deadline its Reliability Coordinator has written into the data specification it received. How is that disagreement meant to be settled?

  1. A. By using the mutually agreeable process the specification identifies
  2. B. By referring the matter to the Regional Entity for a binding ruling
  3. C. By withholding the data until the Reliability Coordinator revises the deadline
  4. D. By applying whichever deadline the Generator Operator's own systems support
Show the answer

Answer A By using the mutually agreeable process the specification identifies

IRO-010-5 R1 Part 1.4 requires the specification itself to identify a mutually agreeable process for resolving conflicts, so that process is the route. Withholding data is not an option, because R3 obliges the receiving entity to satisfy the obligations of the documented specification.

Reference: IRO-010-5 R1 Part 1.4; IRO-010-5 R3

Question 2 · Application

A Transmission Operator realizes that a MW value it sent under its Reliability Coordinator's documented data specification was wrong. Which element of that specification provides for supplying the corrected value?

  1. A. Specific deadlines for providing data and information
  2. B. Provisions to update or correct data and information
  3. C. Performance criteria for the accuracy of data
  4. D. A mutually agreeable format for the data
Show the answer

Answer B Provisions to update or correct data and information

IRO-010-5 Requirement R1 Part 1.5.3 puts provisions to update or correct data and information into the methods the specification sets for data providers. Deadlines, accuracy criteria and format are separate parts of that same list and none of them covers replacing a value already sent.
