LEDs and CSEs: Upgraded Street Lighting in Surrey, UK

Emily Tregidgo – emt2179

1) Sustainability problem: Energy

Street lighting comprises 15-40% of an average city’s energy consumption1. Street lighting therefore contributes to a city’s emissions. In the UK specifically, 60% of the CO2 emissions from the Transport for London Road Network (TLRN) lighting assets are from street lights2.  As such, technology that improves the sustainability of street lighting could be impactful in improving energy consumption, efficiency, and its associated emissions. 

2) Sustainability Technology: LEDs and CMS

  • Urban Control, a smart cities technology company, is partnering with DW Windsor to upgrade Surrey County Council’s street lights. The effort will replace or retrofit 89,000 street lamps. Urban Control will also roll out an upgrade to the existing central management system (CMS).
  • The streetlights will use energy efficient LEDs, which are expected to provide energy savings of ~60%. 
  • The updated CMS will provide the Council with data on the county’s lighting, energy use, and maintenance. 
  • Skanska, the Council’s street light contractor, and Urban Control are also coordinating the roll out of the new program with the decommissioning of the former CMS such that there are no gaps in coverage. 
  • It is anticipated that this technology will save ~7.7k tonnes of carbon emissions each year.

3) Stakeholders

  • Urban Control
  • DW Windsor
  • Skanska
  • Surrey County Council
  • Surrey residents and businesses
  • LED lighting companies

4) The First Three Steps in Deploying This Technology

  • Raise awareness of the changes being implemented amongst the residents and businesses 
  • Ensure stakeholders are coordinated for the replacement and retrofitting process 
  • Monitor the performance of the new system and the data that it collects

One thought on “LEDs and CSEs: Upgraded Street Lighting in Surrey, UK

  1. I’m surprised that this is still a hurdle in the UK! Here in NYC, and across much of the US, conversion of street lights to LEDs is widespread. It’s actually cheaper to replace them than not replace them because of the energy savings. I have watched special sections of film crews swap them back to sodium vapor for ‘period’ pieces (set in the 80s or 90s) so that the scene would look accurate, and then swap them back once they are done filming. (Also an impressive attention to detail, but it really does make a difference in film).
