Power capacity is an essential attribute for any device or system that generates or transmits electrical energy. There are multiple synonyms to describe this characteristic, such as wattage, energy output, electrical power rating, or capacity factor. The wattage refers to the amount of power produced or consumed by an electric circuit per unit of time, usually expressed in watts or kilowatts. The energy output is a general term used to describe the net amount of energy provided by a power system or device over a specified period. The electrical power rating indicates the maximum amount of power that a device is designed to handle continuously without damage or overheating. Finally, the capacity factor refers to the actual power output of a power station or network compared to its maximum theoretical output, highlighting the efficiency and reliability of the system.
