IoT Smart Street Lighting Pilot with TCS (Kolkata Municipal Corporation)

KMC's new streetlight deal with TCS promises up to 27% lower energy costs from centralised, IoT-linked dimming — but as of the February 2026 signing, it's a two-neighbourhood pilot, not a citywide result.

In February 2026, Kolkata Municipal Corporation signed an agreement with Tata Consultancy Services to build a centralised, IoT-enabled street-lighting system, starting with a pilot in the Alipore and Kalighat neighbourhoods ahead of a planned four-zone (north-central, south, east, west) citywide rollout. The system is meant to pair LED retrofits with automated scheduling, intelligent dimming and centralised fault detection, alerting electrical-department staff automatically when a light fails rather than waiting for a resident complaint. TCS and KMC have publicly cited a target of up to 27% lower energy costs and fewer outages, but that figure is the companies' own stated goal from the signing announcement, not a measured result — the pilot had barely begun at review time.
