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.
The authors present a model of an embedded network with PV in an Australian apartment building. Load data from real apartment households are combined with modelled PV generation to describe energy and cash flows over the course of a year. The distribution of costs and benefits between stakeholders is calculated under a range of financial arrangements. Embedded network benefits are highly sensitive to retail and wholesale energy costs at the parent meter and to site-specific capital costs. The addition of PV can, in some circumstances, increase the financial viability of an embedded network and careful tariff design can help incentivise this investment and ensure customer retention.
In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...Read more
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
When South Eastern Australia was in severe drought at the beginning of the century, a whole array of efforts went into addressing the water shortage. Councils introduced, and then increased, water restrictions. Government handed out low-flow showerheads and shower timers,...Read more
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. However, regulatory, technical, financial and organisational challenges have largely prevented Australia's growing number of urban apartment dwellers from accessing these benefits.
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.
This report assesses the prospects for residential solar, batteries and electric vehicles (EVs) in Britain and Germany, and looks at opportunities for near-term growth in the residential solar, battery storage and EV markets.
