Wiener Linien, Vienna’s public transport network operator, wanted to convert its network to LED lights in order to reduce energy consumption and costs. Importantly, this modernisation could not interrupt the operation of the city’s 80+ kilometres of underground rail lines.

In the framework of a 68-month contract, SPIE is in charge of replacing 15,000 lights across the underground rail, bus and tram lines with LEDs. To keep the rail service continuous, SPIE’s teams are working between 1 and 4 a.m., modifying the existing luminaires before installing LEDs. With this project, SPIE is providing sustainable support to the city of Vienna: replacing just 15,000 lights will save an estimated 3500 MWh of electrical power per year, the equivalent of the consumption of 1,200 households.
