True or False: Resource Entities may violate their Corrected Unit Reactive Limit (CURL) or URL if ordered by ERCOT.

True or False: Resource Entities may violate their Corrected Unit Reactive Limit (CURL) or URL if ordered by ERCOT.

• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

Resource reactive limits (CURL and URL) define what a generator can safely provide or absorb under normal operating conditions. But ERCOT can issue emergency instructions that require a resource to operate outside those limits in order to maintain system reliability, such as stabilizing voltages or easing congestion. When such an ERCOT order is in place, the resource may be directed to adjust reactive output beyond its usual CURL/URL, with the understanding that normal limits are restored after the emergency action. This is why the statement is true.
