1. A well construction system comprising:
well construction equipment operable to perform well construction operations;
a power supply system operable to output electrical power to the well construction equipment, wherein the power supply system comprises: an electrical power generator unit installed at a wellsite surface; and an electrical energy storage unit operable to store the electrical power output by the electrical power generator unit,
wherein the electrical energy storage unit is electrically connected to the electrical power generator unit in parallel, such that the electrical energy storage unit operates as a load to the electrical power generator unit when the electrical energy storage unit stores the electrical power output by the electrical power generator unit; and
a control system comprising a processor and a memory storing a computer program code that, when executed by the processor, causes the control system to:
control an electrical power output level of the power supply system during the well construction operations;
control operation of the well construction equipment during the well construction operations based on:
the electrical power output level during the well construction operations; and
an electrical power demand level of the well construction equipment during the well construction operations; and
control operation of the electrical power generator unit based on measured load demand by the well construction equipment and the electrical power available from the power supply system during the well construction operations.
