Street Lighting Bulk Replacement Program

Street Light Street lighting in Stonnington currently accounts for 37% of Council’s total electricity consumption and 28% of corporate greenhouse gas emissions.

Council is aiming to implement a bulk replacement program to convert 3,070 street lights to energy efficient LEDs.

The bulk conversion program is expected to result in a saving of 1,245 tonnes of CO2-e each year, representing 31% of Council’s emissions from street lighting and 9% of Council’s total corporate emissions.

The implementation of the bulk street lighting replacement program will enable Council to progress significantly towards our 2020 corporate greenhouse gas emissions target, taking us to within 1,251 tonnes.

The bulk replacement program will also result in financial savings to Council of approximately $221,000 each year in energy and operating costs.

Implementation

The 3,070 street lights proposed for replacement are owned and maintained by United Energy and Citipower. Council’s energy efficient upgrades will begin in October / November 2017 in the United Energy area with the upgrade of 323 lights. The remaining 2,747 lights in the Citipower zone are to be completed early in 2018.

The project will largely focus on local streets and includes only lights for which Council is fully responsible.

There will be minimal impact on parking and traffic flow. In most cases each light will be replaced in less than 15 minutes. Resident and visitor cars can remain parked on streets during the upgrades.

Council is funding the bulk replacement at a cost of approximately $1.67m over one year.

Why LEDs?

LED lighting technology presents a significant opportunity to reduce energy usage and greenhouse gas emissions, there is also social and safety benefits.

Light levels will be more consistent in the areas where LEDs are installed. The colour of the lighting will be more like moonlight rather than a yellow or orange colour.

  • LED luminaries use approximately 77% less energy than standard mercury vapour street lights resulting in reduced energy costs and greenhouse gas emissions. 
  • LED street lights provide a greater uniformity of light along a street and provide better colour rendering and visibility.  
  • LED lights have a longer lasting usage life (up to 5 times longer) and the light output depreciates less over time.

Street lighting in Stonnington 

The City of Stonnington currently has 7,997 street lights (28% or 2,209 of these are cost shared with VicRoads).

Mercury vapour lights are the predominant light type used on minor roads and residential streets – these are the least efficient form of lighting.

The lights are owned and maintained by two energy distribution companies:

  • United Energy Distribution is responsible for street lights located east of Glenferrie Rd.
  • Citypower is responsible for the street lights located west of and including Glenferrie Rd.

Since 2011 the City of Stonnington has implemented an annual energy efficiency street lighting replacement program focussed on replacing inefficient mercury vapour street lights for which Council is fully responsible.

Prior to 2015 Councils street lighting upgrades utilised 14W T5 fluorescents as these were the preferred technology by the electricity distribution companies. In 2015 the electricity distribution companies approved the use of the more efficient LED luminaires across their respective street lighting networks.

Council has already invested approximately $500,000 and upgraded 1,641 street lights to energy efficient lamps – this accounts for 21% of all street lights in Stonnington.

Council’s energy efficiency street light program has delivered significant benefits including a 22% reduction in electricity consumption and a 20% reduction in greenhouse gas emissions between 2010 and 2015.

The implementation of a bulk replacement of street lights, compared to the ongoing implementation of the annual replacement program, will lead to an additional $774,002 in cost savings and an additional 5,000 tonnes of CO2-e greenhouse gas emission savings over 10 years.

Council’s commitment to upgrade its street lighting stock to more energy efficient technology sits within the context of its wider objective to reduce corporate greenhouse gas emissions by 30% below 2005 levels by 2020.
