As part of the Mayor's pledge to cut CO2 emissions Transport for London (TfL) have started implementing an energy saving plan for main road street lighting, that aims to generate around £1.85 million in savings a year by 2016, while reducing associated CO2 emissions by around 9,700 tonnes a year.

The programme will achieve this by delivering over a 40 per cent saving in energy consumption through replacing 35,000 street lights with LEDs by 2016, via both targeted investment and regular streetlight maintenance. LEDs will be rolled out across the majority of TfL street light during the next 10 years.

TfL will also introduce a Central Management System (CMS) for street lighting across the TfL Road Network (TLRN). This will allow TfL to remotely monitor and manage street lighting and dynamically control levels of lighting.

By aligning lighting levels with traffic flows and road usage at different times of night, TfL expects to significantly reduce both energy consumption and CO2 emissions without compromising road user safety or security. The system will also remotely record lighting values, allowing maintenance crews to restore lighting levels without delay.

Boris Johnson, the Mayor of London, said: “With tens of thousands of lights marking the way on our road network it makes complete sense to focus energy and resources on bringing them up to 21st century standards. This is the largest investment to modernise street lighting on major roads in our capital’s history and will not only cut carbon emissions and save money but it will also lead to even better and safer roads for Londoners.”
