PJM GENERATION OPERATION EXAM
QUESTIONS AND ANSWERS 2026
VERIFIED.
Control center facilities must have a minimum of how many days of fuel for the backup
generator? - ANS 5 days
If PJM ACE shows overgeneration, actual imports are: - ANS Less than scheduled
Who should a generator contact at PJM to clear an outage ticket? - ANS Master Coordinator
To correct for a slow or fast clock, system frequency schedules are offset by: - ANS +/-.02 Hz
What frequency would PJM set to correct for fast-time error? - ANS 59.98Hz
What frequency would PJM set to correct for slow-time error? - ANS 60.02Hz
What info is on an instantaneous reserve check? - ANS synchronized (regulating and non-
regulating), quick start, secondary and beyond secondary reserves
Generators must provide PJM with a realistic Reactive Capability Curve. This curve must have no
less than __ points, and no more than __ points. - ANS No less than 2 and no more than 8
points

, A classic indicator of voltage instability is when system voltages change greatly when... -
ANS system loads change by a small amount
Above the line of a D-curve... - ANS Lagging (pushing VARs). Generators will be set there
during high-load/low voltage conditions.
Below the line of a D-curve... - ANS Leading (absorbing VARs). Generators will be set there
during low load/high voltage conditions.
MWs and MVARs have what kind of relationship? - ANS Inverse (increase in MW = decrease
in MVARs)
How often do generators need to test reactive power capability? - ANS Every 5 years
The computer hardware and software at each control center shall achieve an availability level of
what for those reliability functions directly affect the successful operation of PJM? -
ANS 99.95%
What is EHV? - ANS Extra high voltage. Classified as 345kv and above
Any generator that is a PJM generation capacity resource that has an RPM Resource
Commitment: - ANS 1. Must submit an offer schedule into the DA market even if it is self-
scheduled or unavailable due to outage
2. Generation capacity resources shall submit:
-A schedule of availability for the next seven days
-May submit non-binding offer prices for the days beyond the next Operating Day
What time period is the Market Participant Bid/Offer Period? - ANS 0800-1100
What time are DA Market results posted? - ANS 1330
