The ground-breaking roll-out of 132,000 LED street lights

NORTH America’s biggest roll-out of smart LED street lights is set to turn Montréal into a so-called ‘smart city’ with potential applications such as snow and flood detection, pollution monitoring and waste management.

This month the Canadian city hit a milestone with 50,000 streetlights changed to LED. The changeover includes the simultaneous deployment of a smart lighting management system, part of a five-year £65 million (€72 million, US$82 million) project to transform Montréal into ‘a city of innovation’.

A key element in the project has been city’s insistence on full interoperability among the system’s various components, a first for this type of project anywhere in the world.

‘For us, it was the best way to secure a unique and progressive platform without depending on the technological limitations of a single supplier,’ project engineer Isabelle Lessard told Lux.

The project manager and system integrator is the  Québec business Énergère. DimOnOff, a Québec company specialising in lighting control systems, was chosen for the integration platform, the management software, as well as to supply 20 per cent of nodes and gateways.

The former GE business Current is supplying a total of 60 per cent of the equipment while Telematic Wireless, a world leader in wireless networks, is supplying the final 20 per cent of nodes and gateways.

The city has asked that the smart lighting management system be operational as early as during the first phases of the project, which implied that the replacement of streetlights and the development of the necessary network infrastructure had to be realised simultaneously.

Some potential applications that the city can take advantage of in the future

Around 6,000 high-pressure sodium luminaires are being replaced with LED version every month.  The city estimates it is saving 60 per cent in energy consumption and 55 per cent of equipment maintenance costs as a result of the extended lifespan of LED luminaires.

The new LED lights are also ‘dark sky’ certified, thanks to their custom beam direction meant to limit light pollution in the sky and sleep disruption of the surrounding fauna.

In addition to environmental benefits, the new smart lighting system offers other benefits both for the city and for its citizens. The smart lighting management system allows for real-time measurements of energy consumption, the adjustment of light intensity based on weather conditions, based on traffic or during outdoor events, as well as for swift intervention in the case of broken or malfunctioning streetlights.

Thanks to enhanced colour and contrast perception, the new urban lighting allows for improved visibility for the different road users, thus improving safety. Streetlights located near parks and areas of environmental interest have a warm colour temperature  of 1800K, which the city says ‘does not disturb the circadian rhythm of fauna’.
