LoRaWAN™ compatible streetlight control project, implemented by ENGIE and inteliLIGHT® in Bougival, 15km from Paris, France

The small town near Paris tried other smart lighting systems in the past and chose inteliLIGHT® for its proven functionality and seamless deployment process.

The location and context

Bougival, city of Impressionists, literature and music, with only 8941 inhabitants, is located 17 km west of Paris, on the banks of the Seine. With its walks, its landscapes, its boaters, its restaurants and its hotels, the small town reveals its golden age, late nineteenth century, at the time of the Belle Epoque.

Today, Bougival keeps its character of small town of the Île-de-France while adopting the smart city technologies through inteliLIGHT®. The town tried other smart lighting systems in the past, the implementations did not function properly over time.

The challenge

Bougvial’s town hall looked for a way of improving energy efficiency and reducing operational costs while offering better street lighting services to the community. Besides completely autonomous lighting and detailed street lighting information, the municipality was looking for real-time malfunction alerts to increase their capacity of identifying, repairing and even anticipating lighting malfunctions throughout the city.

Bougvial desired a future-proof, fast and cost-efficient solution that could upgrade existing lighting fixtures without any civil works, allowing at the same time additional investments in the lighting infrastructure without being supplier-locked. A system that could easily integrate with future investments in their smart city vision.

The argument

Reliability won the argument. inteliLIGHT® is an extensively tested solution, already controlling hundreds of thousands of streetlights worldwide, on all continents.

However, there are other characteristics that were taken into consideration: the system works over a LoRaWAN private network, very easy to deploy and with extremely low operation costs. With its coverage of up to 15km, LoRaWAN is fantastic when it comes to lower-density rural and urban areas. Furthermore, the form factor flexibility proved an asset with the embedded controller, that allows upgrading existing lighting fixtures while conserving their architectural output (controllers are not visible on the outside).

Technical solution

The LoRaWAN™ compatible IoT communication infrastructure was chosen due to its capability to reliably connect sensors and actuators over long distances, using low-bitrate public radio frequencies. With its unique penetration capability, a LoRaWAN™ gateway deployed on a building or tower can connect thousands of devices over distances up to 15 kilometers. The technology also offers unique benefits in terms of bi-directionality, security, mobility and accurate localization. The very fast deployment, the possibility to choose between a private or public network architecture and the low operation costs encouraged the adoption of this solution.

inteliLIGHT® FRE-220-M-L LoRaWAN™ compatible luminaire controller (autonomous operation on astronomical calendar, ON/OFF and dimming control, real-time malfunction alerts, full electrical parameter reading) embedded in brand new luminaries.
inteliLIGHT® Streetlight Control Software on the Cloud – autonomous lighting, full grid awareness and control over a visual map overlay, real-time malfunction alerts, advanced reporting and maintenance optimization.

The deployment

A deployment team formed by ENGIE engineers and specialists, with remote technical support from FLASHNET, installed all the equipment in less than two weeks and the system became operational immediately.

The results

inteliLIGHT®’s street lighting control system reduces energy consumption by up to 35% through intelligent ON/OFF switching and targeted progressive dimming.

Furthermore, maintenance teams no longer need to patrol the streets, they receive detailed notifications with any malfunction, including possible defect analysis and necessary materials. iOS and Android compatibility ensure real-time network mapping of the entire grid, street lighting inventory and access to the system’s functions even on the road.
