This is not considered when clearing the DA Market in PJM
What is PJM Load Forecast?
Severe cold weather requires what generators to be staffed, started, and available for loading
What are Combustion Turbines and Diesels?
The minimum requirement for Black Start units runtime
The cost signal PJM sends to generators to provide direction for increasing / decreasing output
What is Dispatch Rate?
The most effective operating point for generators providing regulation during system restoration
What is the middle of their regulation range?
A fuel limited unit is bid into the DA market in this manner
What is Max Emergency?
A fossil steam unit will be considered fuel limited resource when bidding in the DA when it is not capable of running at max output for this number of hours.
What is 72 hours?
Regulation requirement for PJM Balancing area during on-peak hours
what is 1% of forecasted load?
What are Analog/ manual control signals?
During minimum generation conditions, this can be experienced in addition to having excess generation online.
What is high voltage?
PJM does the following to avoid dealing with economic issues during transmission related constraints
What is cost (offer) capping generation?
To maximize MVAR output utilizing a generator's D curve, this action may be taken
What is decrease the MW output of the unit?
The amount of load needed to be shed in order to attain an increase in frequency of 1 Hz
What is 6% - 10 % of load?
A Maximum Generation Emergency Alert will prompt PJM to request this.
What is a Supplemental Status Report (SSR)?
Member actions during Heavy Load Voltage Schedule warnings.

What is weather and day of week?
PJM will call this action to recover ACE so tie line schedules can be maintained.
What is deploy 100% Spinning / sync?
These three items need to be within tolerances before a TO can sync with an outside entity during system restoration.
What is Frequency, Voltage, Phase Angle?
PJM needs to be updated this often when a data link is down.
What is 30 Minutes or agreed upon change?
Triggers of Conservative Ops
What are fuel delivery issues, natural disasters, environmental alerts, GMD, terrorist or sabotage threats?
Generator owners need to report restoration information via restoration form online this often.
What is hourly?
Lagging phase is when current is...
what is inductive?
An emergency alert that prompts Generation Owner and Operators to submit emergency reducible information to PJM control center and the needed criteria!
What is Min Gen Alert and when expected generation levels are within 2500 MW of normal gen limits?
