What is the relationship between heavy loading and the operation of capacitor banks?

Heavy loading conditions typically increase the demand for reactive power on the electrical grid, which is often compensated for through the use of capacitor banks. Capacitor banks are installed to help improve power factor and increase voltage stability by providing reactive power locally. When the load is heavy, there's often a greater need for reactive power, making it more likely that these capacitor banks will be energized to support the overall system. This increase in demand for voltage support and reactive power means that during heavy load periods, capacitor banks become essential to maintaining system efficiency and stability.

In this context, being "more likely to be energized" aligns with the operational dynamics of the electrical system, where increased load necessitates additional reactive power support. This is particularly important in scenarios like industrial electrification where heavy machinery may create significant demand for both real and reactive power.
