We made the decision to play the game with the rules as they were. RACHEL OLLIVIER MANAGER OF SUSTAINABILITY AND WASTE MANAGEMENT, GLEN EIRA COUNCIL Rachel Ollivier, Manager of Sustainability and Waste Management at Glen Eira Council in Victoria, spoke to conference delegates about the process they went through to replace their MV80 lights with more energy effcient T5s. “Each light Glen Eira changed reduced [the council’s overall] energy consumption by 68 per cent,” Ollivier told PWPro. “By changing over 5300 MV80 street lights, Glen Eira City Council has been able to cut its overall reported carbon emissions, by more than 10 per cent.” It took Glen Eira Council roughly two years between developing the business case and starting installation. According to Ollivier, the most diffcult part of the process for them was the lack of deep knowledge of street lighting within the council. She acknowledges the hard work of other councils that paved the way for Glen Eira and others in terms of street lighting programs. “We made the decision to play the game with the rules as they were,” she told delegates. ‘Playing the game’ meant having a strong, articulated business case to incentivise the electricity distribution companies, who own the street lights, to agree to an upgrade to T5s. “Understanding the specifc requirements of each distribution company is important,” said Ollivier. “Some distribution companies may require a council to engage them to do the supply and installation, and not allow engagement of a third party. This may be a quicker process with less risk for council, but doesn’t necessarily give access to true price competition. A strong business case was also important when convincing her CEO to back the project. Ollivier herself has fnancial training and had computed the net present value for the project. While Glen Eira Council’s recent project didn’t use LED lights, but T5 fuorescent lights, the council is investigating LEDs for some other applications. “There is rapid technology change occurring in many energy-related activities which could fow through to street lighting,” says Ollivier. “LED lighting is continuing to evolve and prices are improving so that they are more and more attractive option for wider applications.” ••• PAUL BROWN MANAGING DIRECTOR, IRONBARK SUSTAINABILITY Ironbark Sustainability Managing Director Paul Brown has worked with the Municipal Association of Victoria (MAV) to roll out energy effcient street lighting across the state by 2016. “In the early days we saw T5s dominating,” he told delegates at the conference. “Now we are seeing that LEDs are the prefer red option for councils. “Things are changing rapidly. In the last few months alone War rnambool City Council announced that it will be the frst council in Australia to use LED technology for a bulk changeover of residential street lighting” In his presentation, Brown identifed fve key stages for implementing energy effcient street lighting projects: prepare, fund, defne, procure and manage. “For a bulk street lighting changeover where a council wishes to change all of its residential lights to more effcient alter natives, the frst step is a detailed technical and fnancial business case or feasibility analysis,” he told PWPro. According to Brown, the creation of a business case was the frst step in the Victorian street lighting program that will see 232,000 ineffcient 80w Mercury Vapour lights replaced by energy effcient alter natives. “Once you have developed a business case that demonstrates that a project is technically and fnancially viable, it’s onto funding or fnancing models and then project defnition – lighting design, communications plans and projects plans,” he said. In 2011 Ironbark Sustainability prepared the National Strategy on Energy Effciency on Street Lighting. As a part of the development of this strategy document, it undertook a nation-wide sur vey of 200 organisations. The main barriers identifed by councils were costs (most commonly capital cost), expertise (dealing with the complexity of street lighting) and working with external stakeholders. “But the barriers are no longer there in many jurisdictions,” he said. Brown presented various fnancing options available for councils that are struggling to fnd the upfront capital cost for moving to energy effcient street lighting. He even cited instances where banks have contacted councils to ask about street lighting projects to PWPro.
