Street Lighting is necessary but very expensive to run and they account for approximately 30 per cent of our greenhouse gas emissions. The transition to LED street lighting technology will significantly reduce the Council’s energy consumption and maintenance costs per annum and provide an overall improvement to our street lighting network. The expected annualised savings to Council, is approximately $293,000 per annum once fully installed. There will also be an anticipated annual reduction of 606 tonnes of greenhouse emissions (tCO2-e) once fully implemented.
The new lights being installed will be 82% more energy efficient than existing mercury vapour lamps, require less maintenance and generate a warm to white light (around 4000 Kelvin). The white light generated from LEDs will vary from some existing street lights which can appear yellow (high pressure sodium) and amber (low pressure sodium). Another advantage of LED lights being installed will be less back spill into properties due to improved optics. Although street lights may appear to be brighter (as they are newly installed lights) they will be more efficient in spreading light more evenly along and across footpaths and roads. Visibility along the street will also be improved and look more natural.
Street lighting is important for pedestrian, vehicle and general public safety. Street lighting improves road user safety at night by illuminating roads and footpaths. Street lighting makes it easier for people to drive or walk along streets at night.
Please note: Street lighting is not designed to identify private property locations or provide security lighting, in both metropolitan and rural areas. Street lighting is designed to light our streets and pedestrian walkways only and provide a level of security to these areas.
The changeover to LED lights is being undertaken by Enerven, a subsidiary company owned by SA Power Networks, who have been engaged by City of Mitcham.
Most street lighting in South Australia is operated by Enerven, a subsidiary company owned by SA Power Networks, as a service to Councils and the State Government who both own the street lights. The City of Mitcham pays for electricity used by public street lights (payment made to an energy retailer separately) and maintenance of street lights (payment made to SA Power Networks via lighting tariffs).
This project will only focus on the changeover street lights in local streets. Main road, decorative and public reserve/sporting street lights will not be changed as part of the initial project. Character street lights located in Colonel Light Gardens- Heritage Area, Springfield Estate, Urrbrae, Mitcham Village- Heritage Area, Craigburn Farm Estate, will not be changed to LED during this project.
Enerven will progressively be replacing older lights (predominantly 80W Mercury Vapour lights) on residential streets across Zones 1 to 8 with 14W LED’s (Figure 1). There are larger lights classified as ‘Vehicular (V) road lights’ that are used on major roads, intersections and at traffic control devices, however, energy efficient alternatives are not yet feasible for replacement of these lights. A small number of previously faulty lights have already been replaced with new LED lights across City of Mitcham by Enerven.
Enerven crews will be changing lights from February 2018 across the City of Mitcham. If you would like to find out which suburbs Enerven are currently working in, and which suburbs are upcoming, to find out when the lighting will be replaced in your area please download the Project Progress Report here.
If you are concerned about a street light that may be below standard or require additional street lights please complete the following online form via the City of Mitcham website.
To report a street light not working or operating during day light hours, you can visit the SAPN site here and report the fault. In the first instance you can contact SAPN, on 13 12 61, who will investigate resident requests.
In the first instance you can contact City of Mitcham Customer Service Centre, who will take down your details and forward to SAPN/Enerven if the enquiry can’t be resolved. Residents should remember that the new street lights being installed will result in less glare and back spill into properties due to improved optics. Where a resident can demonstrate that they are being significantly impacted on by light spill into their property from an adjacent street light, a solution will be investigated. In most cases the installation of a shield/visor/shading device will only be considered where it does not reduce lighting levels below the relevant Australian Standards for the lighting for roads and public spaces (AS/NZS 1158). Where a shield is approved, the resident will be required to bear the full cost in accordance with City of Mitcham’s Street Lights – Shading Policy 14.22.
