9. A method comprising:
initiating operation of a power manager at a well construction rig, wherein the well construction rig comprises well construction equipment, power equipment electrically connected to the well construction equipment, and a plurality of power equipment sensors operable to output sensor data indicative of operational status of the power equipment, and wherein the operating power manager:
receives the power equipment sensor data;
receives power management settings entered via a human-machine interface (HMI), wherein each power management setting is associated with a corresponding mode of operation of the power manager;
for each power management setting, changes the mode of operation of the power manager to the mode of operation associated with that power management setting; and
for each mode of operation, causes the power equipment to supply electrical power to the well construction equipment in a predetermined manner with respect to that mode of operation;
wherein when the power manager is in a first instance of the modes of operation, the operating power manager causes the power equipment to supply electrical power to the well construction equipment in a manner that minimizes emission rate of pollutants by the power equipment;
wherein when the power manager is in a second instance of the modes of operation, the operating power manager causes the power equipment to supply electrical power to the well construction equipment in a manner that minimizes consumption rate of fuel by the power equipment; and
wherein when the power manager is in a third instance of the modes of operation, the operating power manager causes the power equipment to supply electrical power to the well construction equipment in a manner that maximizes operational life of the power equipment.
