Current charging methods for network infrastructure and recompense for distributed energy may not result in optimum system solutions. Once feed-in tariffs to support the development of renewable generation are phased out, the payment for grid exports is usually based on the wholesale energy value alone. Network charges are generally levied in full, with few attempts to offer a partial charge, or completely waived. Local Electricity Trading (LET) and Local Network Credits (LNCs) offer one approach to reforming charge structures. This paper examines the effects of LET and LNC on different stakeholders in four virtual trials of medium scale distributed generation projects around Australia, and the implications for policy. The trials found the large value gap between behind the meter systems and grid exports may lead to duplication of network assets, inefficient sizing and operation of distributed generators, and a lack of incentive for dispatchable generators to operate at peak times. The trials indicated that in most circumstances, the combination of LNC and LET addresses all four problems identified to some degree.

Backcasting has been widely used for developing energy futures. This paper explores the potential for using industrial ecology to guide the development of energy futures within a backcasting framework. Building on the backcasting work of Robinson , a seven step method is presented to embed industrial ecology principles within the development and assessment of future scenarios and transition paths toward them. The approach is applied to the case of backcasting regional energy futures in the Latrobe Valley, near Melbourne, Australia. This region has substantial brown coal deposits which are currently mined and used in coal-fired power stations to generate electricity. Bounded by a sustainability vision for the region in a carbon-constrained world, regional industrial ecologies in 2050 were backcast around three themes: bio-industries and renewables (no coal usage); electricity from coal with carbon capture and storage (low to high coal usage); and coal to products such as hydrogen, ammonia, diesel, methanol, plastics and char (demonstrating medium to high overall coal use relative to current levels). Potential environmental, technological, socio-political and economic impacts of each scenario across various life cycle stages were characterised. Results offer a platform for regional policy development to underpin deliberation on a preferred future by the community, industry and other stakeholders. Industrial ecology principles were found to be useful in backcasting for creatively articulating alternative futures featuring industrial symbiosis. However, enabling the approach to guide implementation of sustainable transition pathways requires further development and would benefit from integration within the Strategic Sustainable Development framework of RobÃ¨rt et al. .

The paper is prepared as part of an Australian Renewable Energy Agency (ARENA) funded research project led by the Institute for Sustainable Futures (ISF) at the University of Technology Sydney (UTS), Facilitating Local Network Charges and Virtual Net Metering and a project funded by the Victorian Government Department of Environment, Land, Water and Planning (DELWP), Virtual Renewable Power Stations. A key task in the ISF project is to run five virtual trials of Local Electricity Trading (LET)1 and local network charges, one of which will take place in the Moira Shire and Swan Hill Rural City Council areas in regional Victoria. The Moira and Swan Hill trial will examine either the business model for a one-to-many (Community Power Station) or for a many-to-one (also called a Virtual Power Station, or VPS). Both of these models are likely to be enabled if Local Electricity Trading becomes commonly available. The primary interest of the Councils is to improve the resilience of the local economy by retaining energy spending within the area, to increase the capacity of local renewable energy generation and to enable local residents and businesses to participate in the renewable energy generation. The purpose of this paper is to assist the Councils to choose which model to take forward into a trial.

Parkes Shire Council (PSC) is investigating the options to reduce energy use and generate local energy from renewable or low carbon sources, with the aim of delivering significant financial and environmental benefits. To this end, PSC commissioned the Institute for Sustainable Futures to produce a Distributed Energy Plan to form part of PSCs Sustainable Water and Energy Plan (SWEP). ISF undertook a high level assessment of the energy options by assigning indicative costs and comparing them with projected increases in NSW electricity prices, and assessing risks and benefits in the Parkes context. Six options were selected for further investigation in consultation with PSC. Implementing the proposed Distributed Energy Plan could provide significant economic, social and environmental benefit to both PSC and the wider Parkes community, enabling PSC to invest more in other essential community services and programs. It will directly reduce councils own emissions and costs, and increase the profile of sustainable and low carbon technologies. An important element of the plan is to ensure that the Parkes community is informed about the energy actions implemented, enabling businesses, organisations and residents to learn from the Councils experience. There may be potential in the future to facilitate community implementation of distributed energy, for example by arranging or facilitating bulk purchase cooperatives, so that residents can gain access to the same cost effective solutions as PSC itself.

Meeting Australia's energy needs sustainably will be a major challenge for the next decade. Electricity consumption is forecast to increase by over 20 percent in the next 10 years, while peak electrical demand is increasing even more rapidly, with almost 30 percent growth forecast from 2010 to 2020. Natural gas consumption is forecast to rise by almost 50 percent and gas peak demand is set to increase by around 40 percent by 2020. An unprecedented level of energy sector capital expenditure has been proposed to meet this growth in total and peak demand. Over $46 billion in electricity network infrastructure alone is planned over just the next five years. Electricity generation and gas infrastructure will add significantly to this figure. This unprecedented expenditure is resulting in dramatic increases in consumer energy tariffs
Leichhardt Municipal Council (LMC) has identified sustainability in the use and reuse of water as presenting not only an opportunity to save money and improve amenity in the local area, but also as a means by which to reduce environmental impacts. In line with this, the Council commissioned the Institute for Sustainable Futures (ISF) at the University of Technology, Sydney and HydroScience Consulting to conduct a study of sustainable water use and potential water reuse opportunities. The overall goal of the study is to provide innovative, practical, well-researched water management strategies to reduce potable mains water consumption and reduce the quantity and improve the quality of stormwater runoff within the Leichhardt local government area (LGA). This report represents the principal output of the study and comprises the following two parts: * Part A: .Water Conservation and Reuse Opportunities Study. which identifies and prioritises a number of water conservation and reuse opportunities for particular target sites in the Leichhardt LGA. * Part B: .Water Sensitive Urban Design Opportunities Study. which investigates how LMC can apply Water Sensitive Urban Design (WSUD) principles and associated tools throughout the Leichhardt LGA. Additional outputs from the project include: * An interim report by ISF on water conservation and reuse opportunities; * An interim report by HydroScience Consulting WSUD opportunities; * A series of rainwater tank models for use in sizing tanks for residential and nonresidential applications; and * A series of GIS layers for use in identifying WSUD opportunities.
