Digital Twins for Bharat: Localising Infrastructure Intelligence for Tier 2/3 Cities
Introduction
India is undergoing rapid urban transformation, but much of the spotlight has traditionally focused on Tier 1 cities like Delhi, Mumbai, and Bengaluru. However, the real story of India’s urban growth is unfolding in Tier 2 and Tier 3 cities—towns like Aurangabad, Jalandhar, Belgaum, Bhubaneswar, and Coimbatore. These cities are expected to house over 400 million people by 2030 and play a crucial role in achieving India’s vision of becoming a $5 trillion economy.
To manage this transformation effectively and sustainably, local administrations must turn to innovative technologies. One such promising technology is the Digital Twin—a virtual replica of a physical system, process, or asset that simulates real-time conditions. While Digital Twins are already making waves in developed economies and India’s Tier 1 cities, their application in Tier 2 and Tier 3 cities—collectively referred to as “Bharat”—is still nascent but increasingly essential.
This article explores how Digital Twins can be localized and scaled to improve infrastructure intelligence in Bharat, the challenges involved, global and Indian case studies, investment needs, potential returns, and the roadmap for implementation.
1. What Are Digital Twins and Why They Matter for Bharat?
Definition
A Digital Twin is a virtual model designed to accurately reflect a physical object. This twin can be of a building, road, water system, electrical grid, or even an entire city. It integrates real-time data through IoT sensors, machine learning, and analytics to enable monitoring, prediction, and optimization.
Relevance to Tier 2/3 Cities
Unlike Tier 1 cities, which have relatively established infrastructure and digital maturity, Tier 2/3 cities are still building their foundational systems. This makes them ripe for leapfrogging legacy inefficiencies by adopting Digital Twin technology from the ground up. Digital Twins can:
- Help optimise water, power, waste, and traffic management.
- Support predictive maintenance, reducing unplanned outages.
- Aid in efficient urban planning with better citizen-centric designs.
- Improve disaster resilience and emergency response systems.
- Enable better governance and transparency through data-driven decision-making.
2. Current Urban Challenges in Tier 2/3 Cities
a. Infrastructure Gaps
Most Tier 2/3 cities suffer from poor planning, underfunded municipal corporations, and inadequate access to utilities and civic services.
b. Lack of Real-Time Data
Manual monitoring is still common. Data is fragmented across departments, leading to poor service delivery.
c. Capacity Deficit
Urban local bodies (ULBs) often lack the skilled manpower and digital tools to manage modern urban ecosystems.
d. Rising Urbanisation
These cities are seeing increasing inward migration. Without intelligent systems, this can lead to unplanned growth, congestion, and slums.
3. Components of a Digital Twin System for Bharat
a. Data Collection Layer
- IoT sensors (air quality, water pressure, traffic)
- Satellite and drone imagery
- SCADA systems for utilities
- Crowd-sourced citizen data via mobile apps
b. Integration Layer
- Cloud-based infrastructure
- APIs for integration with existing systems like e-Governance, GIS, Smart City platforms
c. Simulation & Analytics Layer
- AI/ML models for prediction and optimization
- Digital representation of real assets
- Scenario-based simulation (e.g., flood, fire, energy peak)
d. Visualisation & Decision-Making Layer
- Interactive 3D dashboards for administrators
- Mobile and web portals for citizens
- Customised alerts and action triggers
4. Case Studies: Global and Indian Experience
Global Examples
