As the energy sector faces rising electricity demand, increasing adoption of renewable resources, and growing pressure to reduce costs, utilities are turning to advanced technologies to optimize operations. Artificial intelligence (AI), combined with digital twin technology, is emerging as a game-changer in managing energy demand. Digital twins virtual replicas of physical systems like buildings and grids allow utilities to simulate real-world conditions, forecast energy consumption, and design targeted efficiency programs.
By leveraging AI-driven insights, utilities can identify congested areas, optimize distributed energy resources, and implement customer programs more effectively. This approach not only enhances operational efficiency but also supports sustainable energy goals, ensuring reliable service while reducing costs and environmental impact across the grid.
Understanding the Challenge
Utilities today face a complex landscape. Rapid electricity demand growth, rising consumer expectations, and the need for sustainable energy solutions make planning and implementing energy programs increasingly challenging. Program leaders must balance multiple objectives: reducing energy consumption, lowering costs for low-income households, and integrating renewable energy resources—all while maintaining reliable service.
AI and digital twins are emerging as tools to address these challenges by enabling utilities to plan faster, implement smarter programs, and achieve measurable results.

What Is a Digital Twin?
Digital twins have gained attention across industries, particularly in energy. At its core, a digital twin is a virtual replica of a physical system, such as a building, power grid, or industrial plant. It allows engineers and data scientists to simulate real-world conditions and forecast outcomes using advanced models.
Traditionally, scale models of buildings or systems were used for analysis. Physics-based modeling later enabled simulations that could account for factors like weather, HVAC systems, and appliance use. Today, cloud computing allows utilities to generate digital twins of entire service territories in the same time it once took to analyze a single building.
Gregory Donworth, Senior Manager of Data Science, explains, “Digital twins allow us to apply complex mathematical models to predict how systems behave under varying conditions. With the cloud, we can create and simulate millions of these twins in parallel, providing insights at both granular and macro levels.”
Practical Applications in Utilities
Digital twins offer utilities a detailed view of their systems. At the building level, they can evaluate whether homes or businesses have sufficient insulation for local weather conditions and forecast the most cost-effective improvements. At the grid level, utilities can assess the impact of distributed energy resources (DERs) such as solar panels, energy storage, and EV charging stations.
Haider Khan, Vice President of Energy Analytics, notes, “Digital twins help utilities identify congested areas of the grid and predict solutions, from one minute to 30 years into the future. We can analyze top-demand locations and determine how available resources can shift or shed that demand.”
This predictive capability extends from individual buildings to substations and regional networks, allowing for targeted program interventions and optimized grid management.
Current Use and Future Potential
Utilities are increasingly adopting digital twin technology. Initially used for basic supply planning and integrating DERs, the scope now includes high-level transmission and distribution planning, power plant optimization, and accelerated energy efficiency programs.
“The computational power available today allows us to model millions of digital twins—essentially one for each customer—to forecast program performance over decades,” says Khan. This capability enables utilities to simulate the adoption of energy efficiency measures, rooftop solar, and other DERs, providing actionable insights for program leaders.
Building an Effective Digital Twin
Creating a well-functioning digital twin requires three core capabilities:
Foundational System Knowledge
Accurate digital twins depend on a deep understanding of the systems they replicate. For buildings, this includes physics principles like heat transfer, thermodynamics, and fluid dynamics. For grid-level simulations, knowledge of electrical load patterns, distribution networks, and DER integration is critical.
Robust Data Infrastructure
Access to large, high-quality datasets is essential. Utilities leverage historical energy consumption data, normalized load growth projections, and machine learning algorithms to predict future demand. Cleaning, labeling, and organizing data is a vital step in training AI models to ensure reliable outputs.
Cloud Computing Power
Running millions of digital twins simultaneously requires massive computing resources, only feasible through cloud platforms. Cloud infrastructure allows utilities to simulate long-term scenarios and evaluate the performance of programs and technologies across their entire service territory.
Key Insights for Utilities
Digital twins, powered by AI, provide utilities with unprecedented visibility into their systems. By simulating complex scenarios, utilities can:
- Predict the adoption of energy efficiency programs, rooftop solar, and storage solutions.
- Identify grid congestion points and forecast demand shifts.
- Optimize incentives and program design to encourage customer participation.
- Integrate advanced metering infrastructure (AMI) data for real-time insights.
According to Khan, “AI combined with digital twins allows utilities to make smarter, faster decisions. We can identify what programs will work best, where to implement them, and how to optimize resources across the grid.”Harnessing AI and Digital Twins to Optimize Utility Demand Management
