The Australian Renewable Energy Agency (ARENA) has announced a $451,000 investment in  eleXsys Energy, to support the company’s new invention – a device that will help increase the amount of distributed energy resources (DER) that can be connected to the grid. 

Brisbane company eleXsys Energy’s new innovative technology aims to increase the penetration of home solar and batteries in low voltage areas, reducing the need to build costly distribution grid infrastructure. 

The eleXsys device works by regulating voltage on low voltage power lines by dynamically providing or absorbing reactive power, for the benefit of new and existing DER customers where the device is installed. 

By maintaining voltage within normal operating bands, eleXsys can better utilise DER, such as locally produced solar and battery storage. 

The $1.92 million trial will be undertaken in conjunction with local distribution network service provider (DNSP) Energy Queensland, which will undertake testing of eleXsys at its Real Time Digital Simulator facility in Cairns, to show how the device performs across a wider range of network types. 

The project will also benefit from the insights of several other DNSPs participating in a dedicated stakeholder reference group. 

eleXsys Energy will manufacture and install five eleXsys devices, with three being directly connected to Energy Queensland’s network, one being trialled behind the meter on a customer’s premises, and the other being used for testing at the Real Time Digital Simulator facility. 

The final findings of the project will be made public through a comprehensive knowledge-sharing report. 

ARENA CEO, Darren Miller, said technology will play an increasingly important role in adding more renewables to our energy makeup. 

“To help increase the amount of distributed energy we can have on Australia’s energy network, it’s vital that ARENA supports these new technologies such as the eleXsys which not only help to connect more home solar and batteries, but also helps to avoid expensive network augmentation works to support increased demand,” Mr Miller said. 

“ARENA is excited to be supporting eleXsys Energy’s trial of the eleXsys device. After a successful trial in south east Queensland, we could see the technology installed across the grid to save costs for users while also enabling more distributed renewals to be connected to the grid.”

eleXsys Energy CEO, Dr Bevan Holcombe said, “ARENA’s support and that of Energy Queensland are critical to demonstrating applications of eleXsys in the residential DER market, and how existing distribution grids can be supported to host much more exported solar energy than is typically the case in Australia today.” 

ARENA has previously supported over $100 million of DER projects and established the Distributed Energy Integration Program (DEIP), a collaboration of government agencies, market authorities, industry and consumer associations aimed at maximising the value of customers’ DER for all energy users. 

Federal Assistant Minister to the Minister for Industry, Energy and Emissions Reduction, Tim Wilson, said, “With one in four households powering the nation through rooftop solar, and another 2,000 added every business day, we’re investing $450K to boost their contribution to the grid,  so they play a bigger role in our carbon neutral future.

“eleXsys Energy has employed dedicated personnel with deep experience to deliver the  project. This funding will help eleXsys Energy continue to engage industry partners and support local jobs in Queensland.”
