In electrical systems, load refers to the amount of power being consumed at any given moment. Electrical utilities must constantly balance generation with load to maintain stable power supply. Peak load occurs during periods of highest demand, typically hot summer afternoons when air conditioning use spikes or cold winter evenings when heating and lighting needs combine. Managing load matters for municipalities operating their own utilities, planning facility electrical systems, and working toward energy efficiency goals. Understanding electrical load helps in sizing electrical equipment, planning for backup power, and identifying opportunities to reduce energy consumption and costs.
