Why AGL’s new grid-forming battery is ‘genuinely cutting edge’

Australian giant AGL Energy plans to build what will be the world’s largest ‘grid-forming’ battery in South Australia, deploying technology so novel that it yet to be clearly regulated in Australia. “Trialling something like this on the grid at this scale hasn’t been done before anywhere in the world,” Josh Birmingham, Director of Large-Scale & Project Solutions at SMA Australia, told pv magazine Australia.

World’s largest ‘grid forming’ battery to begin construction near Adelaide

Australian giant AGL Energy will soon own the world’s largest ‘grid forming’ battery, with construction on its 250 MW/250 MWh big battery to begin later this year at Torrens Island, just north of Adelaide in South Australia. The battery will be delivered by Finnish technology company Wärtsilä with inverters supplied by German company SMA Solar Technology.

Saturday read: In conversation with UNSW’s Anna Bruce on distributed transformation

The time is now for the energy consumer, says Anna Bruce, as energy “prosumers” produce, consume, and provide electricity and grid services in previously unimagined ways. Bruce, a senior lecturer at the University of New South Wales’ School of Solar Photovoltaic and Renewable Energy Engineering (SPREE), leads work on the role of distributed energy resources in the energy transition, analysing firsthand the dizzying level of complexity it brings.

Solar manufacturers warn of 12-18 months disruption for standalone products

Potential price rises of 14% for the solar home systems that are driving access to electricity in the world’s under-served regions could signal further arrested progress towards the UN goal of universal access by 2030.

Australia’s ‘unsafe’ solar installation standards under fire

Australia is a world leader in the uptake of rooftop solar but the head of Queensland-based renewable energy company REA Global has labelled the nation’s solar installation standards out of date and unsafe.
