Lighting on the lights of Grenoble

The energy transition is also a matter of streetlights! The City of Grenoble has set an example by studying viable energy solutions for all its heritage, including street lighting. With its new Lighting Plan implemented since 2015, the City aims to drastically reduce its energy costs by modernising all its installations.

This is not the first thing you pay attention to when you walk the streets… and yet, the quality of public lighting is essential to the well-being of residents. It is for this reason that Olivier Curto, head of the Régie Lumière at the City of Grenoble, accompanied by its president Alan Confesson, proposed a night stroll on the occasion of City-zen Days in order to see more clearly on this Plan Lumière.

Led by the Régie Lumière of the City of Grenoble, the Lighting Plan implemented in 2015 for a period of 8 years aims to achieve a more intelligent management of public lighting. This means saving energy and limiting light pollution while improving the quality of services and lighting.

All this has been made possible thanks to a massive renovation of the heritage. All mercury lamps have been replaced and the City will be equipped with more than 56% LED lamps by 2023. In addition to having a longer life span (10 years), LED lights optimize the network thanks to their scalable lighting. They vary in intensity during the night, which, coupled with a dimming system by detection, will eventually reduce energy consumption by more than half.

By eliminating 80% of light pollution and providing residents with reliable services in the event of a problem, the Light Plan improves the quality of life while being part of an efficient energy transition approach. Good point.
