1. A method comprising:
receiving, at a processor, a first control signal comprising an instruction to adjust an energy generation output level of an energy generation (EG) system to a first energy generation output level;
maintaining the energy generation output level of the EG system at the first energy generation output level for a time period;
determining, by the processor, whether a second control signal is received during the time period, wherein the second control signal comprises an instruction to adjust the energy generation output level; and
if a second control signal is not received during the time period: (i) ramping down the energy generation output level at a rate after the time period until a failsafe output level is achieved, and (ii) maintaining the failsafe output level until a third control signal is received by the processor, wherein the failsafe output level is based on a historical load requirement.
