Improving energy efficiency with hybrid-enabling technologies and demand-side management

Doug Cook, Managing Consulatant Marchment Hill Consulting

In a bid to improve energy efficiency, a range of systems can be implemented such as the integration of renewable energy sources with existing power systems and maximising power management to decrease dependency on fossil fuels and produce cleaner energy. Demand-side management allows users to effectively manage and improve energy efficiency by shifting your power supply at times of peak demand.

Providing greater energy efficiency with renewable energy, while also being able to maintain a reliable source of power, hybrid-enabling technologies can be introduced and integrated with existing generators. Correctly sizing the mix of energy sources ensures that the renewable energy source is capitalised on while also maintaining a stable supply of power. 

Energy efficiency and cleaner energy can be achieved with the integration of renewable energy sources, such as photovoltaic as seen in the recent upgrade at Bikenibeu Power Station located in South Tarawa, Kiribati. The power plant originally consisting of diesel generators, is now running as a fully automated renewable power plant and incorporates hybrid interface with dynamic spinning reserve. The project upgrade will see significant savings in costs, diesel fuel and reduction in carbon dioxide emissions for the remote island. 

Rottnest Island, Western Australia has recently seen the initiation of a large-scale hybrid project combining renewable energy and smart controls to reduce the amount of diesel fuel required to produce clean drinking water and generate power for the remote island. The project has allowed the power station to integrate with wind, solar and water storage integration, while also being able to engage in demand-side management. 

Another example of a demand-side management project involved the landmark QV1 building in Perth’s business district. The 43-storey tower has three standby sets that with an upgrade can now enable the import and export of power and take advantage of a demand-side management scheme. With utility specified protections, the power generation plant can synchronise with the electrical utility allowing bump-less transfer of load in a Demand-side management program event. The system also ensures that if there is a mains blackout, the generators can switch over and take the building’s load and then transfer the load back to the grid when the mains comes back on line.


Economic Fuel Switching - Reverse-cycle air conditioners as Heat Pumps

Tim Forcey, Energy Advisor, (formerly) University of Melbourne

Reverse-cycle air conditioners have been installed in millions of Australian homes. However many Australians are unaware that switching them on in winter may be the cheapest way to heat a home or business. The potential consumer win is huge: hundreds of millions of dollars per year could be saved. Many people are unaware that reverse-cycle air conditioners are heat pumps that harvest renewable ambient heat, or that they rank in Australia's renewable energy Big 4. In fact, Australian reverse cycle air conditioners are a larger source of renewable energy than all rooftop solar panels combined. To be covered in this presentation is this and other key points of our University of Melbourne Energy Institute research report "Switching Off Gas - An Analysis of Declining Gas Demand in Eastern Australia".
