PJM TRANSMISSION LATEST 2026 QUESTIONS AND
SOLUTIONS GUARANTEE A+
✔✔When PJM's estimated Operating Reserve requirement is less than the forecasted
Primary Reserve requirement, what emergency procedure does PJM dispatch issue? -
✔✔Primary Reserve Alert
✔✔A voltage reduction action is performed at what level of the electrical system? -
✔✔Distribution
✔✔ When is Manual Load Dump Warning issued? - ✔✔available primary reserve
capacity is less than the largest operating generator or the loss of a transmission facility
jeopardizes reliable operations after all other possible measures are taken to increase
reserve
✔✔Why is a Voltage Reduction used? - ✔✔PJM dispatcher issues the order for a 5%
voltage reduction on the DISTRIBUTION system. Used to increase transmission system
voltages by lowering the distribution system voltages
✔✔When is Primary Reserve Warning issued? - ✔✔The purpose of the Primary
Reserve Warning is to warn members that the available primary reserve is less than
required and present operations are becoming critical. It is implemented when available
primary reserve capacity is less than the primary reserve requirement, but greater than
the synchronized reserve requirement.
✔✔At what Frequency (Hz) do generators trip offline due to under frequency? - ✔✔57.5
Hz
✔✔When is Minimum Generation Alert issued? - ✔✔Minimum Generation Alert is
implemented when the expected generation level is within 2,500 MW of normal
minimum energy limits.
✔✔Under normal conditions, when is a generator considered Fuel Limited Generation?
How many hours of run time left? - ✔✔Generally, any fuel or resource restricted unit (<
72 burn hours at max capacity, see Section
6 of this manual) should be classified as Fuel Limited Generation.
✔✔What category should Furl Limited Resources be placed in during a Cold or Hot
Weather Alert? - ✔✔Units bid to the PJM Market when Conservative Operations/Cold or
Hot Weather Alert have been declared and PJM Dispatch requests Fuel Limited
Resources be placed into the Maximum Emergency Generation Category.
✔✔At what projected temperature will PJM issue a Hot Weather Alert? - ✔✔90 degrees
F or more
