Power capacity

Definition

Power capacity refers to the maximum amount of electrical power that an energy system, such as airborne wind energy systems, can generate at any given moment. This measurement is critical because it helps determine the efficiency and effectiveness of energy production, especially when integrating energy storage technologies to ensure a stable and reliable power supply during variable wind conditions.
