Answer each one before you open the explanation. On the exam there's no explanation, and you have about 77 seconds a question on RC and BT, 90 on TO and BI.
A Reliability Coordinator is writing the stability-limit section of its SOL methodology. What must that section say about limits whose impact reaches more than one Transmission Operator or another Reliability Coordinator Area?
- A. Which Transmission Operator holds the limit in Real-time
- B. Which Transmission Planner reviews the limit each year
- C. How the Reliability Coordinator establishes those limits
- D. How the cost of any resulting redispatch is shared out
Show the answer
Answer C How the Reliability Coordinator establishes those limits
FAC-011-4 R4 Part 4.3 requires the SOL methodology to describe how the Reliability Coordinator establishes stability limits when there is an impact to more than one Transmission Operator in its Reliability Coordinator Area or to other Reliability Coordinator Areas. Which entity later holds or reviews the limit is not what this Part addresses.

With no Contingency having occurred, flow on a 138 kV circuit rises above its Normal Rating at 06:40 and the Transmission Operator relies on the circuit's 2-hour Emergency Rating. By what time must System adjustments have returned the flow below the Normal Rating?
- A. At 07:10
- B. At 07:40
- C. At 10:40
- D. At 08:40
Show the answer
Answer D At 08:40
FAC-011-4 R6 Part 6.1.1 lets an Emergency Rating carry no-Contingency flow only while System adjustments that return the flow within its Normal Rating can be executed and completed inside that rating's specified duration. Two hours from 06:40 expires at 08:40; the 30-minute figure that appears in the communication rules of R7 is a different clock.
