Head-end system is the central hub in energy management that facilitates communication, data processing, and control across utility networks. It collects and processes data from advanced metering infrastructure (AMI), such as smart meters and sensors, enabling utilities to monitor energy usage, detect faults, and manage demand in real-time. By centralizing data and streamlining operations, head-end systems ensure efficient energy distribution, optimize grid performance, and support reliable decision-making. These systems play a vital role in enabling automation, enhancing grid reliability, and improving the overall efficiency of energy management systems.
