1. A system for providing backup power to a facility, comprising:
- a generator; and
a controller configured to;
operate the generator until a condition is met;
determine a load history that occurs while operating the generator until the condition is met;
determine a cool-down time based on the determined load history; and
run the generator to the point when the condition is met and in an unloaded condition for the cool-down time.

Abstract
A system for providing backup power to a facility includes a generator and a controller. The controller is configured to operate the generator until a condition is met, determine a load history that occurs while operating the generator until the condition is met, determine a cool-down time based on the determined load history, and run the generator to the point when the condition is met and in an unloaded condition for the cool-down time.

9. A method for providing backup power to a facility, comprising:
-
operating a generator until a primary power is restored to the facility; determining a load profile while operating the generator before the power was restored; determining a cool-down time based on the load profile; and running the generator to the point when the power is restored and in an unloaded condition for the cool-down time. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory computer-readable medium tangibly embodying computer-executable instructions to:
-
operate a generator until a condition is met; determine a percentage of full load while operating the generator until the condition is met; determine a cool-down time based on the determined percentage; and run the generator past the point when the condition is met and in an unloaded condition for the cool-down time. - View Dependent Claims (18, 19, 20)
