Urban infrastructure management is undergoing a profound transformation, driven by the convergence of digital twin technology and artificial intelligence. In a recent panel discussion at the SmartCitiesWorld Summit 2026, industry leaders and city officials explored how these tools enable local authorities to operate smarter—optimizing energy systems, transportation networks, and public services while building long-term resilience. The conversation highlighted that the path to truly intelligent cities lies not just in deploying technology, but in rethinking procurement, governance, and community engagement.

Digital twins—virtual replicas of physical assets, systems, or processes—allow cities to simulate, predict, and optimize operations in real time. When integrated with AI, these models can analyze vast amounts of data from sensors, cameras, and IoT devices to identify inefficiencies, forecast maintenance needs, and even test policy changes before implementation. This combination is particularly powerful for managing complex urban systems like energy grids, water supplies, and transit networks.

Strategic Procurement as a Tool for Resilience

Sam Markey, Founder of Recurve, argued during the panel that strategic procurement remains one of the most underutilized tools for cities striving to build resilience and climate impact. Rather than simply buying the cheapest products, cities can use procurement to stimulate local economies, prioritize sustainable materials, and pilot innovative digital solutions. For example, when a city specifies that bids for streetlight upgrades must include IoT sensors and AI-based analytics, it creates a market for smart infrastructure while reducing long-term operational costs. Markey emphasized that procurement can also be a vehicle for equity, requiring vendors to provide job training or subcontracted opportunities for underrepresented groups.

Historically, municipal procurement has been risk-averse, focused on low bids and proven technologies. However, the panel noted that the urgency of climate change and the rapid pace of digital innovation demand a shift toward outcome-based contracts. Cities like Barcelona and Helsinki have already adopted such approaches, issuing tenders that specify performance targets (e.g., reduce energy consumption by 30%) rather than prescribing specific hardware or software. This flexibility encourages vendors to propose cutting-edge AI and digital twin solutions tailored to local conditions.

Energy Systems Transformed by Renewables and Digital Twins

A key theme of the panel was how local authorities can shape energy systems through renewables, flexibility, storage, and smarter networks. Digital twins enable city planners to model energy flows from solar panels, wind turbines, and battery storage across entire districts. AI algorithms can then optimize when to store excess energy, when to draw from the grid, and how to balance supply with demand—especially important as more electric vehicles and heat pumps come online.

For instance, the city of Sunderland has repositioned itself as a leading smart city by integrating low-carbon innovation with digital infrastructure. Its digital twin of the central business district includes real-time data on energy use, traffic patterns, and building occupancy. The city uses this model to manage its district heating network, adjust street lighting based on pedestrian activity, and plan for new renewable installations. According to the panel, such integrated approaches not only reduce emissions but also save money—Sunderland expects to cut energy costs by 20% over the next decade.

Similarly, Dublin has employed digital twin projects to improve services and quality of life. The Irish capital uses a city-scale digital twin to simulate traffic flows and test interventions like new bike lanes or congestion pricing. The AI engine learns from historical data and real-time sensor inputs to suggest optimal traffic signal timings, reducing travel times and emissions. Dublin’s economic growth strategy also leverages the twin to attract investment by showing potential developers the impact of proposed buildings on local infrastructure.

Mobility and Transit: AI in Action

The panel also examined how AI is reshaping transport operations. Tom Gerend, executive director of the Kansas City Streetcar Authority, explained how the return of rail has revitalized downtown Kansas City. The streetcar line, which opened in 2016, now carries over 5,000 passengers daily and has spurred more than $1 billion in private development along its route. But the real innovation lies in how the authority uses AI to optimize operations. Predictive maintenance algorithms analyze data from onboard sensors to flag potential failures before they cause delays. AI-powered scheduling adjusts service frequency based on real-time demand, improving reliability without adding more vehicles.

Beyond streetcars, AI is being applied to bus fleets, paratransit services, and even bike-sharing systems. Microsoft’s Katherine Flesh, another panelist, noted that the greatest opportunities for AI in transportation depend on strong data foundations, workforce readiness, and responsible governance. Cities must invest in data storage, integration platforms, and training for staff—otherwise, the best algorithms will fail due to poor input data. Flesh also warned of risks: biased AI could reinforce systemic inequities if training datasets omit certain neighborhoods or demographics.

Cybersecurity and Smart Lighting

Smart lighting systems are a growing entry point for cities adopting digital twins and AI. The panel referenced the "Cities Thriving on Lighting" podcast episodes that explore how global cities approach smart lighting and cybersecurity risks. An interconnected streetlight network, when managed by AI, can automatically dim or brighten based on ambient conditions, motion sensors, and special events. This not only saves energy but also improves public safety. However, each light pole with a sensor and communication module becomes a potential vulnerability. The panel stressed that cities must embed cybersecurity from the start—choosing encrypted protocols, segmenting networks, and conducting regular penetration tests.

One practical example comes from Los Angeles, which has deployed 500,000 smart streetlights. The city’s digital twin includes a live map of every fixture, with AI identifying outages, flickering, or tampering. The system also integrates with traffic management and emergency services, so lights flash to guide first responders during incidents. Yet Los Angeles has also suffered cyberattacks that temporarily disrupted lighting controls, reinforcing the need for robust defenses.

Data Foundations and Governance

A consistent thread throughout the panel was the importance of data management. AI and digital twins are only as good as the data they consume. Cities are generating massive amounts of information from utility sensors, traffic cameras, weather stations, and citizen smartphones. But raw data is useless without proper labeling, cleaning, and integration. The panel recommended that cities create data governance frameworks that define ownership, privacy rules, and interoperability standards. For example, Dublin’s digital twin uses open data standards so that different city departments and private partners can share information seamlessly.

Workforce readiness emerged as another critical factor. Retiring baby boomers leave a skills gap, but younger workers may lack institutional knowledge about legacy infrastructure. AI can help by providing decision-support tools that capture expert knowledge and model outcomes. However, city employees must be trained to trust and critique AI recommendations. Several cities have established "digital academies" to upskill current staff, from budget analysts to public works engineers.

Case Studies: From Kansas City to Sunderland

The panel highlighted several cities that are leading the way. Kansas City’s streetcar project not only transformed transit but also catalyzed riverfront development and reconnected historically divided neighborhoods. The streetcar authority uses its digital twin to simulate the impact of new stations and land-use changes, showing how infrastructure investments can reshape growth patterns. In Sunderland, the city has built an entire low-carbon district powered by a microgrid that integrates solar, wind, and battery storage—all managed by the digital twin. The city plans to expand the twin to include social housing, schools, and healthcare facilities, creating a truly holistic management system.

Dublin’s approach combines digital twins with community engagement. Residents can access a simplified version of the twin through a mobile app, where they can see planned changes and provide feedback. This transparency builds public trust and helps city planners avoid costly missteps. The panel noted that such citizen-inclusive models are essential for long-term success, as smart city initiatives often fail due to lack of public buy-in.

Looking Ahead: Challenges and Opportunities

While the potential is enormous, the panel acknowledged significant challenges. Digital twins require substantial upfront investment—not just in software but in sensor infrastructure, data storage, and personnel. Many cities struggle with siloed departments that resist sharing data. Moreover, AI models can perpetuate biases if not carefully monitored. The panel agreed that standardized metrics and open-source platforms could help smaller cities adopt these technologies without reinventing the wheel.

Ecomondo, a prominent green technology event that also participated in the broader SmartCitiesWorld discussions, emphasized that sharing practical solutions across cities is key. The panel concluded that no single city can solve all problems alone, but by collaborating—through conferences, open data exchanges, and joint procurement—urban leaders can accelerate the transition to smarter, more resilient infrastructure. The era of operating blindly is ending; with digital twins and AI, cities have the tools to see into the future and act decisively.
