PJM instructs a generator to come online; what is the effective operating time based on?

The effective operating time for a generator coming online in response to PJM's instruction is determined by the sum of notification time and start-up time. Notification time refers to how quickly the generator is informed of the need to produce electricity, while start-up time is the actual duration it takes the generator to ramp up to full production after receiving that notification.

This combined measure reflects the realistic timeline for a generator to become operational and deliver electricity to the grid following PJM's directives. Factors like operational readiness, scheduled maintenance, or fuel supply are relevant to overall operations, but they do not specifically define the effective time it takes for a generator to be ready to produce power once instructed by PJM. Understanding these components is critical for effectively managing the grid's supply and demand dynamics.
