$9.6 million to support consumer energy revolution

To support the transition to an electricity network that is increasingly powered by small-scale energy assets, ARENA has announced $9.6 million in funding for 12 new projects and studies.

The announcement includes $7.21 million for five projects that trial new ways to maximise the amount of distributed energy that the network can accommodate, while maintaining the stability of the system.

A further $2.38 million has been allocated to seven studies that will investigate how high penetrations of distributed energy can be successfully integrated into the energy market and grid.

With the highest number of rooftop solar installations per capita – at two million households and counting – Australia is already pioneering ways to integrate distributed energy resources (DER) into a grid designed last century for large centralised power stations.

Distributors and the market are working hard to accommodate the rise of behind-the-meter assets and make sure the transition delivers an electricity network that is more stable and affordable.

Even as world leaders for rooftop solar uptake, Australia’s transition has barely begun. Challenges are set to grow sharply as more rooftop solar and batteries are installed, electric vehicles become more popular and new technologies like smart appliances start hitting the mainstream.

One of the five projects to receive funding will trial software on the NSW electricity grid that acts as a ‘traffic controller’, with the ability to remotely increase or decrease the output from customer owned assets to manage grid congestion.

Led by Zeppelin Bend and also receiving funding from the NSW Government, the evolve project has received $4.29 million from ARENA to show a way forward that allows more customers to connect solar and storage to the distribution network.

Today electricity distributors have few tools available to manage high concentrations of rooftop solar. Rather than restrict new connections, or invest in costly infrastructure, the project could unlock a way for distributors to coordinate individual household systems and ‘evolve’ with the changing mix of renewables and DER.

Jemena are trialling three technologies to address these challenges. Installed in two areas where high levels of solar uptake are stretching the network, the project aims to develop tools to orchestrate the customer owned assets to preserve the stability and reliability of the system, while allowing more distributed resources to connect. The project has received $1.12 million from ARENA.

The RACV have received $273,000 in funding towards their $608,000 project to develop a prototype smart hot water system that can be aggregated into a centrally controlled network. Showing the potential of smart appliances, the system will use energy usage predictions and weather forecasts to optimise the the use of excess solar power to heat water.

Not only would using solar on site improve the value of electricity generated, limiting the flow of excess energy back into the grid could allow more households to connect while also improving the stability of the network.

ARENA CEO Darren Miller said rooftop solar, batteries and other customer-related energy technologies will shape the energy system of the future.

“We are looking at how we can make the most of of the growth in distributed energy resources as consumer choice expands and changes the way we generate and use energy,” Mr Miller said.

The success of rooftop solar is a sign of things to come. Today there are more than two million solar rooftops nationwide, up from just 14,000 systems a decade ago.

“It is projected that up to half of all electricity could be generated by consumers within the next few decades, up from around 4% today,” he said.

Amongst the studies to receive funding, researchers from the Australian National University will explore how community energy projects can reduce costs for consumers, while also growing the amount of renewable energy and storage that can be installed. The $1.37 million study aims to promote more community energy projects – both here in Australia and around the world.

The project will develop software that can examine the value of the different models of community energy projects that have been rolled out to date. These tools will be used to develop tariff structures that encourage individual households to participate in collective schemes, and also guide the most effective use of distributed energy generation and storage.

“This is a huge change and will require innovations in software, hardware and thinking to achieve the best outcome for consumers,” Mr Miller said.

The new announced funding round will build on other work ARENA is undertaking in the consumer energy space. Last year ARENA announced the Distributed Energy Integration Project (DEIP) – an initiative bringing together energy peak bodies, market authorities, industry associations and consumer associations to enhance the potential of consumer owned energy resources.

Distributed energy projects awarded nearly $10 million

On behalf of the Australian Government, the Australian Renewable Energy Agency (ARENA) has today awarded $9.6 million in funding to 12 projects and studies to further integrate distributed energy resources (DER) into the electricity system.

ARENA is providing $7.21 million to five pilot projects led by Zeppelin Bend, Jemena, SA Power Networks, Solar Analytics and RACV. Each project will trial novel approaches to increasing network hosting capacity with the objective of allowing the system to operate securely whilst maximising the ability of distributed energy, such as solar PV, to provide energy to the grid.

A further $2.38 million has also been allocated to seven studies led by CitiPower & Powercor, Dynamic Limits, University of Tasmania, CSIRO, Oakley Greenwood, the Australian National University and the University of Melbourne. The studies will investigate how to successfully integrate high penetrations of DER into the grid and into the energy market.

DER encompasses behind-the-meter technologies such as rooftop solar, home batteries, inverters, controllable loads both in homes and commercial and industrial facilities, electric vehicle charging points, smart appliances and systems (such as fridges, air conditioning systems, hot water heaters and pool pumps) as well as relevant enablers such as smart meters and data services.

Among the five projects funded is the Evolve project led by Zeppelin Bend, funded with the NSW Government, which will see software trialled on the NSW grid that will act as a traffic controller able to send signals to DER assets to increase or decrease their energy output to manage grid congestion.

The seven studies include an ANU study on community energy models and a CSIRO study to prepare a model of the low voltage grid for public use.

ARENA CEO Darren Miller said these 12 projects and studies will help to maximise the potential benefits of DER technologies owned by households and businesses.

“Rooftop solar, batteries and other customer-related energy technologies are set to play a key role in shaping the future energy system. It is projected that up to half of all electricity could be generated by consumers within the next few decades, up from around 4% today. This is a huge change and will require innovations in software, hardware and thinking to achieve the best outcome for consumers,” he said.

“ARENA is extremely excited to be funding some of the best experts in the energy sector to build network hosting capacity technology and further understand the impacts of DER and to identify, and ultimately solve, the technical limits of our electricity grid,” Mr Miller said.

The funding initiative complements work that ARENA is already undertaking in the DER space, including the announcement last year of the Distributed Energy Integration Program (DEIP); an initiative that has the energy industry working together to enhance the potential of consumer owned energy resources. DEIP is a collaboration of energy peak bodies, market authorities, industry associations and consumer associations.

“We are looking at how we can make the most of of the growth in distributed energy resources as consumer choice expands and changes the way we generate and use energy,” Mr Miller said.
