Bin Lu, EVP global power products, Schneider Electric looks at energy transition.
For much of the past two decades, the energy transition has been viewed primarily through the lens of generation. Renewable deployment, grid-scale storage, transmission expansion and nuclear investment all remain critical. However, an equally important challenge is emerging much closer to where electricity is consumed.
The next constraint on our energy system is increasingly the last mile: the low-voltage electrical infrastructure that distributes power throughout commercial buildings, industrial facilities and critical infrastructure. As electrification accelerates, this is where many of the next generation of engineering challenges will need to be solved.
Electrification is changing the rules
Electric vehicle charging, heat pumps, AVAC systems and rapidly expanding digital infrastructure are introducing larger and less predictable electrical loads. At the same time, greater adoption of renewable energy increases the need for flexibility across the electricity system.
Together, these changes are reshaping low-voltage electrical distribution. Buildings are evolving from passive consumers of electricity into active participants in a more connected, responsive energy system.
Historically, electrical distribution has been designed around three core objectives: safety, reliability and availability. While these remain fundamental, most installations were developed for relatively stable demand profiles and have offered limited visibility into how electrical capacity is used once commissioned.
Today's electrical systems are considerably more dynamic. Commercial buildings now combine EV charging, rooftop solar, battery storage, heat pumps and increasingly sophisticated building management systems. Manufacturing facilities are electrifying production processes, while data centers continue to expand to support cloud computing and artificial intelligence.
These changes are increasing the complexity of electrical distribution at exactly the point where available capacity is often most constrained.
In many cases, the challenge is not simply generating more electricity. It is ensuring existing low-voltage infrastructure can accommodate changing demand efficiently, safely and economically. This is where Energy Intelligence is becoming increasingly important.
Energy Intelligence is transforming electrical distribution
At its simplest, Energy Intelligence is an intelligence layer that connects electrical assets, operational data and energy systems to provide meaningful insight and support better decisions in real time. It combines connected electrical equipment, embedded sensing, communications and software to create visibility across the electrical distribution network within a building or facility. By bringing together data from connected devices, it enables organizations to anticipate changing conditions, optimize performance and support operational decisions rather than simply responding to events after they occur.
For electrical engineers, the value lies not in connectivity for its own sake, but in what that connectivity enables.
Rather than relying on periodic inspections or isolated measurements, engineers can continuously monitor electrical performance across the installation. They can understand how capacity is being utilized, identify changing load profiles, monitor power quality, detect abnormal operating conditions and make informed decisions about how electrical assets should be managed.
The objective is not simply collecting more data. It is giving context to operational data so that electrical systems can anticipate changing conditions, optimize performance and support timely operational decisions. By bringing together energy, operational and asset data, organizations gain a clearer understanding of how their electrical infrastructure is performing and where greater flexibility and efficiency can be achieved.
Managing electricity demand more effectively
Consider a commercial building adding EV charging and electric heating. At first glance, this may appear to require a larger grid connection or major investment in new electrical infrastructure. In reality, the constraint is often not total capacity, but when demand occurs. Multiple high-power loads operating simultaneously can create short-duration peaks that exceed available capacity, even when overall daily energy consumption remains well within acceptable limits.
An intelligent electrical distribution system can help address this challenge by understanding how loads interact and coordinating them more effectively. EV charging can be scheduled dynamically according to available capacity. HVAC systems can respond to occupancy and environmental conditions while avoiding unnecessary demand spikes. Battery storage, where installed, can support short periods of high demand before recharging during quieter periods.
These adjustments are largely invisible to building occupants but can significantly improve infrastructure utilization while avoiding unnecessary investment in additional network capacity. The same principles apply across industrial facilities, hospitals and data centers.
Building a more resilient electricity system
Many of today's capacity constraints exist much closer to consumers. Local substations, distribution transformers and low-voltage feeders all have finite capacity. When neighboring buildings simultaneously increase demand, local infrastructure experiences the greatest strain.
Building more generation alone does not resolve these constraints. Greater flexibility is also needed within the electrical systems connected to the network. When buildings can stagger flexible loads and make better use of existing infrastructure, they collectively contribute to a more resilient electricity system.
In this sense, Energy Intelligence benefits not only individual buildings but also the wider grid. It allows buildings to become active participants in balancing demand while providing engineers with greater operational visibility throughout the lifecycle of an installation. It creates a connected system capable of adapting to changing operating conditions and supporting a more flexible energy network.
As our energy system becomes more distributed and complex, future flexibility is becoming just as important as installed capacity. Intelligent electrical systems can be upgraded incrementally rather than requiring wholesale replacement, allowing buildings to evolve alongside changing energy demands. This is key to improving the efficiency, resilience and longevity of last-mile electrical distribution.
Improving maintenance
Electrical assets naturally degrade over time, but conventional maintenance often relies on periodic inspections or fixed service intervals. While effective, these approaches cannot always identify developing issues between inspection cycles.
Continuous monitoring provides a different perspective. Changes in current, voltage, temperature, power quality or switching behavior can provide early indications that equipment performance is changing. By analyzing these trends over time, engineers can identify potential issues before they result in unplanned failures, allowing maintenance to be planned around actual equipment condition rather than predetermined schedules.
This approach is particularly valuable in environments where electrical reliability is business critical, such as manufacturing, healthcare, transport and data centers, where unplanned downtime carries significant operational and financial consequences.
Energy Intelligence is grounded in operational data
Artificial intelligence is expected to play an increasingly important role in analyzing growing volumes of operational data. However, general-purpose AI alone lacks the physical understanding required for mission-critical electrical infrastructure. Effective Energy Intelligence depends on hardware performance models built on accurate operational data from connected assets. When intelligence is grounded in physical reality rather than assumptions, it becomes a practical engineering tool that helps anticipate issues, optimize performance and support better operational decisions.
For more than a century, the primary role of low-voltage electrical distribution has been to deliver power safely and reliably. That responsibility remains unchanged. What is changing is the expectation that electrical infrastructure should also provide operational insight, support flexible energy use and strengthen the resilience of both buildings and the wider electricity system.
As electrification accelerates, Energy Intelligence at the point of use will become as fundamental to electrical distribution as protection, reliability and power quality are today. The next generation of electrical infrastructure must not only distribute power safely and efficiently, but also provide the operational intelligence needed to make better use of every available kilowatt. The success of the energy transition will depend not only on how much electricity we generate, but on how intelligently we distribute, manage and use it.
