The savings will contribute towards the £41m the authority needs to find for 2016/17 and will be achieved through several techniques:
- 17,000 of the county’s 68,000 lights will be swapped for low-energy LED ones which can be dimmed
- ‘Part-night’ lighting is being introduced, mainly in residential areas, where lights will turn on at dusk and, in many cases, remain on until midnight. Lights will then be switched off until morning. This will affect 38,000 street lights
- Up to 3,000 street lights, away from built up areas, have been identified for possible switch off, subject to further assessments.
There will be no changes to street lighting at some locations, including those where:
- There are road safety features such as zebra crossings or speed humps
- There is a significant record of night-time crime
- There is sheltered housing, warden-controlled accommodation or a care home.
Cllr Richard Davies, executive member for highways, said: “We have to reduce our annual spending by £170m over the next four years which means we cannot provide services at the level we have been doing. It currently costs £5m a year to maintain and run our street lights, so this is a sensible way for us to reducing our spending and it’s also good for the environment. Our carbon footprint will be reduced by over 6,000 tonnes of CO2 per year, which is a third of our five year target. There will also be less light pollution.
“We already install low-energy lights that can be dimmed where we can, and when existing ones come to the end of their lifespan we consider if they are even still needed - so this project is nothing new, we are just accelerating the savings that can be made. Local authorities in North Yorkshire, Derbyshire and Norfolk have also introduced similar initiatives.”
Engineers will be making these changes between April 2016 and March 2017.
