Peak load refers to the maximum amount of demand for electricity or energy that a power grid or electrical system must meet at any given time. Synonyms for "peak load" can include high demand, maximum capacity, peak demand, or peak power consumption. These terms are often used interchangeably in the energy industry to describe the period of time when energy consumption is at its highest levels. During peak load times, consumers can experience higher energy costs, while utilities may struggle to maintain sufficient supply to meet demand. Despite this, improvements in energy efficiency and the use of renewables are helping to manage peak loads and balance energy demands more effectively.
