India & Its Smart Cities: What Got Built, What Works, What's Pending

India adds roughly the population of a new Mumbai to its cities every three years. The Smart Cities Mission was launched in 2015 to make sure that growth is liveable, sustainable, and — crucially — data-driven. Ten years on, here is where things actually stand.

What is a "smart city" in the Indian context?

Globally, a smart city uses sensors, data and connectivity to run services efficiently. In India, the Ministry of Housing and Urban Affairs (MoHUA) framed it more pragmatically: core infrastructure + clean environment + decent quality of life + smart solutions. Reliable water first, dashboards second.

The 100 cities were selected through a competitive "Smart City Challenge" between 2016 and 2018, from Bhubaneswar and Pune to Agartala and Kavaratti.

How was it built?

Special Purpose Vehicles (SPVs)

Each city created a company (SPV) jointly owned by the state and the urban local body to plan, fund and execute projects — a model borrowed from infrastructure finance to bypass slow municipal processes.

Integrated Command and Control Centres

All 100 cities now run an ICCC: a "brain" that fuses CCTV, traffic signals, air-quality sensors, and emergency services. During COVID-19, these centres became war rooms for contact tracing and oxygen logistics.

Area-based development + pan-city solutions

Roughly 80% of the funding went into retrofitting or redeveloping specific neighbourhoods (smart roads, LED lighting, 24×7 water). The rest funded city-wide platforms like intelligent traffic management and e-governance apps.

Impact and growth so far

• 7,000+ projects worth over ₹1.4 lakh crore completed across the 100 cities.
• Indore has been India's cleanest city seven years in a row, powered by a data-driven waste-management model now copied nationwide.
• Surat and Pune run adaptive traffic systems that cut junction wait times by 20–30%.
• Bhubaneswar and Visakhapatnam have citizen apps for grievances that resolve most complaints within 48 hours.
• GIFT City in Gujarat is India's first operational greenfield smart city and international financial hub, with district cooling and automated waste collection.
• Spin-off programmes — Smart Cities 2.0 (CITIIS), the National Urban Digital Mission, and India Urban Data Exchange (IUDX) — are pushing open data and interoperability.

Pending targets and honest gaps

Being a TruCitizen^™ means celebrating progress and naming the gaps.

• Uneven completion: A few cities have finished 90%+ of projects; others hover near 60%. Deadlines were extended to 2025.
• Financing: Municipal bonds and PPPs raised less than planned; most money still came from central and state grants.
• Beyond the 100: India has 4,000+ statutory towns. The real test is scaling ICCC-style governance to Tier-2 and Tier-3 cities at a fraction of the cost.
• Climate resilience: Urban flooding in Bengaluru, Chennai, and Gurugram shows that sensors alone don't fix drainage. Smart Cities 2.0 puts sponge-city design and heat-action plans at the centre.
• Digital divide: Citizen apps only work if everyone can use them — accessibility and Indic-language support remain patchy.

What's next: the 2047 city

Expect digital twins (virtual replicas of a city used for simulations), AI-optimised bus routes, rooftop-solar micro-grids, and 15-minute neighbourhoods. The Union Budget's Urban Challenge Fund (₹1 lakh crore) signals a shift from "100 smart cities" to "every city, smarter".
