Tallinn has been consistently replacing sodium street lights with modern LED street lights in recent years, saving hundreds of thousands of euros per year in both maintenance and electricity.
The widespread uptake of LED lamps in Tallinn started in 2014
and has been particularly reinforced in recent years. In 2019,
there were 60 592 street lights in Tallinn, including 8 664 LED
luminaires; two years later, the total number of luminaires was
66 993, including 25 386 LED luminaires. Last year, 10 444 new
LED lights were added to the urban space. Since 2019, the share
of LED street lighting has increased from 14.3 per cent to 37.9
"The introduction of LED luminaires is an example of how
investments made in the past can help save taxpayers money
today. Saving hundreds of thousands of city budget while
increasing in the number of luminaires is an example of how
green investments can also be economically beneficial," said
Deputy Mayor Vladimir Svet.
While the number of luminaires on city streets has increased by
a tenth in the last three years, real electricity consumption
fell by 10 percent last year, and by December 2021, the figure
was already 15 percent. So it is investment in LED lamps that
has helped to achieve significant savings in a situation of
high electricity prices. For example, the electricity cost for
street lighting in December last year alone would have been
more than €200 000 higher without LED luminaries. The energy
consumption has been reduced by more than 4,000 MWh compared to
2019, saving hundreds of thousands of euros per year, and with
rising electricity prices this amount will increase further.
Investments in LED lamps will continue this year. In 2022, the
city plans to invest €5.5 million in deploying LED lights.
