In the United States alone, the grid is comprised of hundreds of thousands of miles of high-voltage transmission lines and millions of miles of distribution wires that stretch across the country, interconnecting cities, towns, and rural areas. It is then supported by tens of thousands of substations that bring together diverse generation sources such as thermal plants, hydropower facilities, and increasingly, solar and wind farms and battery energy storage systems. These in turn deliver that energy to demand centers such as factories, data centers, and households. Yet, many critical elements remain disconnected from IT systems. And without connectivity, utilities lack visibility into equipment conditions, power flows, and overall system performance that they would otherwise have access to in real time.
AI readiness begins by building a digital foundation across three layers: connectivity, intelligence, and data management.
Connectivity involves equipping physical assets with sensors, software, and secure communications networks so they can be monitored and controlled. Intelligence is then applied by integrating these assets with operational technology (OT) platforms such as protection and control systems, while linking them with IT networks to enable secure, bidirectional data flow. Finally, effective data management consolidates information from (often) siloed systems and transforms it into actionable insights through applications such as advanced distribution management systems (ADMS), asset performance management (APM), and energy optimization platforms.
Together, these layers transform isolated equipment into integrated, intelligent systems capable of supporting AI applications.
Hitachi Energy’s technology stack - developed in collaboration with companies in the broader Hitachi Group– captures this layered approach and is illustrated in the below graphic, reflecting how physical assets, connectivity, cybersecurity, and applications come together to create a grid that is both reliable today and ready for AI-driven operations tomorrow.
At the base are the physical assets that utilities already own. By introducing sensors, connectivity software, and cybersecurity, utilities can connect these assets into a secure digital environment. Once connected, the data becomes a strategic asset that can be applied across multiple functions.
Continuous monitoring of equipment health through asset management tools, for example, can extend asset lifecycles and reduce maintenance costs. Distribution networks can be optimized in real time using ADMS and automation systems, helping utilities integrate higher levels of renewable energy without compromising stability. Predictive analytics can also be applied to energy trading and optimization platforms, improving financial performance by strengthening participation in power markets and enabling more precise grid balancing.
