What minimum full-demand fuel supply are you required to have onsite for an emergency generator?

For emergency generators, it is critical to have an adequate fuel supply to ensure that they can operate continuously during power outages or emergencies. The standard requirement is that generators must have enough fuel onsite to operate for a minimum period of time, allowing them to maintain essential services and functions.

Choosing five hours' worth of fuel supply reflects industry best practices and guidelines that account for the anticipated duration of most emergency situations, providing a buffer during initial response and recovery efforts. This amount helps ensure that the generator can sustain operations while waiting for further assistance or resolution of the power issue, such as refueling or restoration of utility power.

In many healthcare and critical infrastructure settings, being prepared for a minimum of five hours is a recognized standard that balances the need for readiness against practical considerations of logistics and fuel management. Therefore, having this minimum amount of fuel aligns with safety regulations and operational readiness, ensuring that facilities can continue to provide vital services during prolonged outages.
