At the Bouygues Energies & Services offices of Enertrans AG in Niedergösgen, Switzerland, a showcase of 11 intelligent solutions simulating a smart city has been set up, covering a few hundred square metres.
The demonstrator was inaugurated in late 2022 and shows how site operators, local authorities and municipalities can reduce their environmental footprint and manage infrastructure more energy-efficiently. It also shows how services can be adapted to inhabitants’ needs and how new ones can be introduced to improve daily life.
This includes integrated lighting concepts, Smart mobility & Smart security installations as well as green energy systems such as hydrogen generators and the first Wattway pedestrian photovoltaic panels.
A comprehensive solution turns a community into a smart, connected and sustainable city
Local authorities are increasingly considering energy-saving solutions. So far, there are a lot of individual solutions from different suppliers, but they are not linked to each other or even managed in a holistic and transparent way for the residents.
In “the world’s smallest smart city”, Niedergösgen showcases a comprehensive solution: sensors and a flying robot collect data transmitted via LoRaWAN or WiFi technologies, the data is analysed and analysed on a dashboard. Based on these analyses, the solutions applied – Smart Energy & Environment, Smart Public Security, Smart Mobility – can be monitored and controlled intelligently.
For example, thanks to a solution provided by Bouygues Energies & Services, public lighting data can be collected, analysed and used to jointly create new services. This miniature Smart City also shows ways of extending the use of existing lighting infrastructure, such as charging stations for electric bicycles or cars.

How about Smart bins and parking?
Smart solutions for waste management and parking are also featured. For example, by equipping public waste bins with sensors to show how full they are, they can be emptied as soon as needed. Refuse truck rounds can then be managed more efficiently and overflowing bins are a thing of the past! This solution has already been used successfully in Niedergösgen.
In terms of parking, smart camera surveillance systems and the allocation of free parking spaces prevent lengthy searches for parking and make the public space safer.
All the solutions featured are designed for energy efficiency, but still require electricity. This is why we combine the smart and sustainable city with green electricity generation, such as the first Wattway pedestrian photovoltaic panels or the Hydrospider green hydrogen plant.
