Which type of power is supplied to large commercial facilities from the utility company?

Large commercial facilities typically receive three-phase power due to its efficiency and capacity to handle high power loads. This type of power is essential for operating heavy machinery and large electrical systems commonly found in industrial and commercial settings.

Three-phase power utilizes three alternating currents, each reaching its peak at different times, which allows for a more stable and continuous power supply. This results in less voltage drop and more consistent energy delivery, making it ideal for powering motors and large equipment that require a significant amount of energy.

Single-phase power, while used in residential applications, is generally insufficient for the higher demands of commercial environments. Direct current power is less common in large facilities because it requires more complex systems for generation and distribution. Alternating current power is a broader category that includes both single-phase and three-phase forms, but three-phase power is specifically designed for large-scale commercial energy needs.
