An example well construction system includes well construction equipment, a power supply system, and a control system. The well construction equipment performs well construction operations. The power supply system outputs electrical power to the well construction equipment. The power supply system includes an electrical generator unit and a control system including a processor and a memory storing a computer program code. The computer program code causes the control system to control an electrical power output level of the power supply system during the well construction operations. The computer program code also causes the control system to 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.

Power management at a wellsite

Electrical power transmission for well constriction apparatus via a rotatable spool positioned at and affixed to a moveable well construction apparatus at a wellsite and an electrical power cable at least partially wound on the rotatable spool and connected to stationary equipment at an end of the electrical power cable distal from the rotatable spool.

Electrical power transmission for well construction apparatus

Apparatus and methods pertaining to a moveable well construction apparatus to be electrically energized via an electrical power transmission path extending between a stationary power source and the moveable well construction apparatus. The path comprises cables and connectors. A system comprises a detector operable for generating information indicative of whether the path is properly installed. The system permits the path to be electrically energized when the detector-generated information indicates the path is properly installed, and prevents the path from being electrically energized when the detector-generated information indicates the path is not properly installed.
