Energy efficiency, sustainability and environmental protection – these are the goals that are achieved with LED technology in street lighting. As is currently the case in the town of Plattling in Bavaria, where Bayernwerk, one of E.ON’s regional energy distributors, has upgraded the street lighting to state-of-the-art and efficient LED technology costing around one million euros. The Plattling project is just one example of many that E.ON is implementing throughout Germany.
Altogether, E.ON’s regional companies bear responsibility for almost 800,000 lights including the associated cable network – making it the biggest operator of street lighting systems in Germany. Here, the “lights” refer to individual street lamps, but in some cases one lamp can contain two or more lights.
More than ten percent of the street lighting operated by E.ON is now equipped with energy-saving, bright and efficient LED lights – and it’s a growing trend. After all, in purely arithmetical terms, this technology enables savings of 400,000 euros per year compared to conventional lighting in a town of 100,000. This not only eases the burden on the authority’s finances, but ultimately also on the taxpayer.
To ensure that lighting in public streets and squares can be more straightforward and cheaper in future, E.ON is carrying out several pilot projects in which it is testing new lights and lighting control systems, which supply data about their current state of operation or send a message to a mobile phone or an e-mail address automatically in case of disruption. In addition, with one click of the mouse or using saved timetables, the strength of the lighting can be regulated, and late at night when there is not much traffic it can be reduced.
This sort of link between modern hard- and software offers not only solid savings, but also a point of entry into further digital solutions. In future, smart streetlights could be used, for example, to report CO2 values, fine dust pollution, data from traffic counts or free parking spaces to a central control room.
