1. A well construction system comprising:
well construction equipment operable to construct, at a wellsite, a well that extends to a reservoir;
a power supply system operable to output electrical power to the well construction equipment to facilitate operation of the well construction equipment and at least in part operable to generate electrical power using gas produced from the reservoir; and
a control system configured to control the well construction system, wherein the control system comprises a processor and a memory storing a computer program code, and wherein the control system is operable to:
store a digital drilling program comprising:
an equipment operational plan indicative of a sequence of planned well construction operations to be performed by the well construction equipment over a period of time to construct the well, wherein each planned well construction operation in the sequence of planned well construction operations is scheduled to be performed at a respective time within the period of time; and
an electrical power plan indicative of a planned electrical power demand of the well construction equipment to perform the sequence of planned well construction operations;
determine an electrical power output capacity indicative of a total electrical power that the power supply system can output to the well construction equipment to perform the sequence of planned well construction operations;
compare the electrical power output capacity to the planned electrical power demand;
based on the comparison, adjust the sequence of planned well construction operations to adjust the planned electrical power demand by adjustment of at least one of a speed of, an acceleration of, a pressure generated by, and a flow rate output by a component of the well construction equipment to perform the sequence of planned well construction operations; and
optimize performance of the power supply system based at least in part on availability of the gas produced from the reservoir; and
cause the well construction equipment to perform the sequence of planned well construction operations indicated in the equipment operational plan.
