• Enedis and Toulouse Métropole are testing a real-time public lighting fault detection system.

  • It is based on the external Linky meters and a very small radio transmitter.

  • The rapid reporting of anomalies can be extended to public buildings and help reduce the energy bill.

When a light bulb burns out or a whole group of streetlights falls apart, there is little hope that the problem will be resolved quickly, if only because of the time it takes to report to the competent services, legitimately not really reachable in the middle of the night. Unless an alert system speeds up the process. This is what Toulouse Métropole and Enedis have been experimenting with “life-size” since November 2020, via the outdoor Linky meters, in around ten sectors of the Pink City where, for example, the public lighting system may be aging. .

Smart meters can detect peaks or jumps in consumption and it is also a classic service that the operator already offers to communities, with for Toulouse, the dissemination of consumption data on the metropolitan OpenData.

But for now with a 24 hour deadline.

Extend to forgotten heaters or lighting

But Toulouse metropolis has shown itself to be more ambitious: it challenged Enedis to find a real-time alert system.

The idea, explains the community, "is to instantly retrieve information on consumption, in order both to better manage consumption but also to intervene in real time on the network in the event of a failure".

With #Linky, @Enedis is experimenting with @TlseMetropole and #Occion a solution to manage the energy consumption of # Public Lighting in real time and detect any anomalies.

"To achieve this, we approached the Albigensian company Occion which has developed a wireless radio transmitter that can be" plugged "on the Linky meter," explains Stéphane Lesénéchal, regional director of Enedis.

Provided that the correct interface is developed during this one-year experiment, the failure can be reported in real time to the technical services.

For reasons of public tranquility but also of controlling consumption in the event of an anomaly, this efficiency would be an indisputable strategic and technical advantage.

“Especially, enthuses Stéphane Lesenechal, that the system could be extended to public buildings.

It could make it possible to indicate a heating which has remained on during the holidays in a school, a room which has remained lit in a museum ”.

What to lighten the bills.
