This paper aims to revisit the way that distributed energy resources (DERs) interact with the present structures of the Australian National Electricity Market (NEM), and consider opportunities to improve the interface between centralized and distributed resource operation and investment.
Local electricity sharing schemes have the potential to play an increased role in the Australian National Electricity Market as the penetration of distributed energy resources (DERs) continues to grow. These models allow participants to share energy between separately owned and operated DERs, however are largely untested.
This paper outlines opportunities for, and barriers to, increasing PV deployment on apartment buildings in Australia. With PV penetration reaching 40% of residential dwellings in some parts of the country, access to renewable energy for the 14% of Australians who live in apartments has lagged behind.
Over 1.7 Australian households have taken the opportunity to generate some of their own power and reduce both their electricity bills and carbon emissions by installing rooftop photovoltaic (PV) systems on their homes.
Despite potential advantages of load aggregation and scale discounts, few of Australia's 2.3 million apartment residents are amongst the country's 1.8 million solar prosumers. However, embedded networks can be used to distribute rooftop photovoltaic generation to households if split incentives and regulatory barriers are overcome.
Significant interest exists in the potential for electric vehicles (EVs) to be a source of greenhouse gas (GHG) abatement. In order to establish the extent to which EVs will deliver abatement, however, a realistic understanding of the electricity and transport sector GHG emissions impacts arising from different approaches to integrating EVs into the power system is required.
Despite unsupportive political conditions for renewable energy (RE) in Australia, a new movement is emerging. About 70 Australian community groups have started to embrace the concept of community renewable energy (CRE) and develop their own projects. However, faced with a complex institutional environment and the absence of national government support, only a few groups have established operating CRE projects as yet. In this situation the role of local government (LG) ‘closest to the people’ deserves more attention.
Growth in peak electricity demand poses considerable challenges for utilities seeking to ensure secure, reliable yet affordable energy provision. A better understanding of the key drivers of residential peak electricity demand could assist in better managing peak demand growth through options including demand-side participation and energy efficiency programs.
Power Purchase Agreements (PPAs) with utility-scale renewable energy plants allow medium to large-scale electricity consumers to meet a proportion of their load demand using renewable electricity. This allows them to reduce their greenhouse gas (GHG) emissions, while at the same time reducing their exposure to volatile and peak prices in the National Electricity Market (NEM).
