Energy Storage

Tesla chair Robyn Denholm expects the company to double its EV sales in Australia by the year’s end, hoping to see its flagship product catch up to its Powerwall sales. Denholm also said Australia needs to expand its lithium refining and processing capacity at “sprinting pace” to properly capture the global battery opportunity.

An international research team has developed a new way to evaluate the economic value of energy storage technologies. They went beyond pure cost assumptions to consider the benefits that such technologies could bring to energy systems.

Australian renewables developer Edify Energy has secured more than $13 million in federal and state government funding to help finance the installation of a 25 MW/50 MWh battery energy storage system featuring advanced inverter technology next to its 275 MW Darlington Point Solar Farm in south-west New South Wales.

The Australian Energy Market Operator has declared approximately $12.7 billion of investment in new transmission lines should begin “as urgently as possible” to accelerate the transition to renewable energy and energy storage, replace exiting coal-fired power plants, and deliver a more efficient and effective grid in eastern and south-eastern Australia.

The operator of the 150 MW/193 MWh Hornsdale Power Reserve in South Australia has been fined $900,000 after being sued by the Australian Energy Regulator for failing to deliver on its promise of providing services essential to maintaining the stability of the power grid.

Queensland government-owned generator CS Energy has announced plans to build the largest grid-scale battery in the state at Greenbank in Brisbane’s outer southern suburbs. The 200 MW/400 MWh project will be delivered in partnership with Queensland network operator Powerlink.

Australian renewable energy tech start-up Okra Solar has raised $3 million to scale up distribution of its solar-based hardware and software solutions and electrify more than 290,000 off-grid homes in Nigeria in the next three years while expanding its operations in Haiti and other countries.

A couple of weeks ago, Goldman Sachs sent shockwaves through battery metals markets, issuing a prediction that cobalt and lithium in particular were due for a sharp price decline in the next two years. But London-based Benchmark Mineral Intelligence is loudly pushing back, outlining its reasons why it believes the call on lithium was wrong. Meanwhile, US analyst Wood Mackenzie says that the battery raw material chain will remain tight, but notes that recycling could help to ease the supply deficit.

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.

The US multinational will expand the solar and battery energy storage manufacturing capacity at its factory in Tamil Nadu to 9 GW per annum by the end of 2022. The factory manufactures the FlexInverter power conversion solution and the FlexReservoir utility-scale energy storage systems.
