Sydney-based solar company Solaray Energy says its inquiries have doubled since the federal election, rebounding back to the record demand seen in 2020 ad 2021. Moreover, the company’s director and co-founder Jonathan Fisk says interest in batteries is “making solar fly,” with half of the potential new customers looking to add storage.

The Queensland government this morning confirmed it will not be changing solar feed in tariffs after Murdoch newspapers claimed a ‘sun tax’ was looming for the state. Meanwhile, New South Wales recommended upping feed in rates for solar households.

Oil and gas giant BP will take a 40.5% stake in the 26 GW Asian Renewable Energy Hub megaproject proposed for Western Australia’s north coast.

Western Australia is set to exit coal-fired power by the end of the decade as state-owned power provider Synergy will close its two remaining coal plants by 2029 in response. Western Australia Premier Mark McGowan said coal was no longer viable due to the high-penetration of solar, particularly rooftop. McGowan also announced a $662 million boost for the coal-town of Collie’s industrial transition and $3.8 billion in statewide renewable investment, with a focus on energy storage.

UK scientists have compared the performance of lithium-ion storage systems and vanadium redox flow batteries for a modeled 636 kW commercial PV system in southern California. They have found that both technologies, coupled with an oversized PV array, could achieve a levelised cost of electricity of less than US$0.22/kWh (AU$0.32/kWh), while offering a self-sufficiency ratio of 0.95.

There is enormous demand for renewables to enter the grid, and for power purchase agreements to make use of them. However, as more renewables feed into the grid at intermittent periods, the risk of “revenue cannibalisation” increases. Swiss consultancy Pexapark’s latest report looks at the “cannibalisation effect” and how the solar PPA market can adapt.

As Australia’s energy crisis deepens with Queensland and NSW again cautioned over potential blackouts in the coming hours, director of the Victoria Energy Policy Centre, Bruce Mountain, told pv magazine Australia commentators have underplayed the extent to which energy generators have exacerbated the emergency. Government intervening to take charge of the energy market is, for him, the most likely outcome as generators withholding capacity increasingly threatens to cause massive losses in state economies.

Edify Energy has completed the financing for its grid forming 150 MW / 300 MWh battery energy storage system. The system will be made up of three separate batteries in the Riverina region of NSW which have gained approval to operate in ‘virtual synchronous generator’ mode.

Selected projects will be awarded a fixed rate under a 20-year contract under the country’s renewable energy certificate (REC) scheme and will sell electricity to local power distributors.

Japan’s Rinnai has unveiled what it claims is the world’s first 100% hydrogen combustion technology for residential water heaters. It is currently using the hydrogen water heater in demonstration projects in Australia, prior to commercialisation.
