When PJM experiences problems with their primary digital control signal, it sometimes becomes
necessary for companies with the capability, to switch to the back-up signal.
This backup signal is known as: ✔Correct Answer-Analog control
When PJM sends cost signals to generators, to provide direction for increasing or decreasing the
facility output, this signal that is sent is known as: ✔Correct Answer-Dispatch Rate
Under normal operating conditions, what is the limit that will provide the lowest output level of
a generating unit? ✔Correct Answer-Eco Min

adjust the output of the unit base on the unit's ✔Correct Answer-price or cost curve
incremental

PJM members? ✔Correct Answer-eMarket
PJM's ACE configuration is such, that when the ACE is positive (+), it indicates ✔Correct
Answer-too much generation
If a generator is self-scheduled, what is the minimum notification time required in order for the
MW output to be adjusted? ✔Correct Answer-20 minutes prior to the change

changed to implement the correction, how much is the frequency scheduled adjusted by?
✔Correct Answer-+ /- 0.02 Hz
When PJM runs their Regulation test, how long do the tests normally run? ✔Correct Answer-
40 minutes
Your system has a 300 MW steam unit, but due to oil deliveries, the on-site fuel supply is
diminishing.
