- The minimum load on a power station over a standard period
baseload - Investment & Finance Definition
The minimum amount of electric power that an electric company can deliver over time at a steady rate. Baseload capacity is determined by the kind of stress that electric generating equipment can handle if it is operated on an around-the-clock basis. On a hot day, demand for electricity increases as more people turn on their air conditioning. This demand can overwhelm the baseload, resulting in power surges, blackouts, or grayouts.
