What scenario would necessitate putting a generator online?

A generator is typically put online to ensure a continuous supply of power, especially when there is a risk of insufficient electrical supply due to external factors. In the scenario of performing work on the electrical distribution that feeds the facility, putting a generator online provides an alternative power source to maintain operations while the primary source is temporarily unavailable or unstable. This ensures that essential systems and processes continue to run without interruption.

Scheduled maintenance checks usually involve shutting down equipment rather than bringing additional generators online. When malfunctioning equipment is detected, the response often involves troubleshooting and repairs rather than immediately adding more capacity with a generator. The manufacturing of new generators also does not require putting an existing generator online, as this activity is unrelated to the operational power supply needed at that moment. Thus, the scenario of work being done on electrical distribution feeding the facility clearly identifies the need for a generator to maintain consistent power delivery.
