What capability is defined as a generating unit's ability to start and synchronize within 15 minutes?

The capability defined as a generating unit's ability to start and synchronize within 15 minutes is known as Fast Start. This terminology is used within the power generation sector to describe units that can reach operational readiness quickly, allowing them to respond to fluctuations in demand or system requirements in a timely manner. Fast Start units are particularly valuable in managing grid stability and supporting intermittent renewable energy sources by providing backup power when needed.

In the context of power generation, the emphasis on a quick response time ensures that generators can effectively contribute to the reliability and stability of the electricity supply, especially during peak load times or unforeseen outages. The distinction of "15 minutes" is critical, as it highlights the requirement for these units to not only start up but also synchronize with the grid in a short time frame, enabling them to be integrated into the power supply system quickly.

Other terms, while they may have similar connotations regarding rapid deployment or activation of power generation resources, do not specifically denote the precise technical capability of synchronizing within the specified time frame like Fast Start does.
