Energy Storage

Australia’s energy ministers have unanimously agreed to establish a capacity investment mechanism that they anticipate will unleash at least $10 billion (USD 6.7 billion) worth of investment and at least 6 GW of renewable energy generation and storage to stabilise the grid as the nation’s ageing coal-fired power plants exit the energy market.

Construction has officially commenced on Western Australia’s first pumped hydro project but the state government has indicated it won’t be the last, hinting that the 1.5 MW renewables microgrid being built at Walpole could serve as a blueprint for the roll out of similar projects both nationally and overseas.

Researchers from the University of Sydney have created a new sodium-sulphur battery which they say provides four times the energy capacity of lithium-ion batteries and is far cheaper to produce, providing the potential to dramatically reduce energy storage costs.

French renewable energy giant Neoen has secured development approval to build a 1 GW /4 GWh big battery in Western Australia as the state government seeks to ramp up energy storage capacity to support its planned transition from coal-fired power to renewables.

A poll of more than 2,000 Australians has found 78% agree the federal government should expand the national rooftop solar subsidy to include household battery storage. The concept has floated around for the last years, most notably in the form of a federal bill tabled by independent MP Helen Haines, but may have an uptick of support amid spiralling energy prices.


A free version of SunSPOT, a tool for tailored guidance on the ideal solar and battery set ups, has now been launched. Developed by APVI and UNSW, the online tool allows users to calculate size, cost and potential savings from household renewable systems and is the only such platform offering this information without a sales motive.

Panasonic claims that its new vehicle-to-home system can increase the self-consumption rate of residential solar and storage capacity to 90%.

Australia’s only solar panel manufacturer, Tindo Solar, has announced a doubling of sales for both solar panels and battery storage in recent months. The manufacturer attributes the boom to the concatenation of rising energy costs, a potential recession, and increasing consumer awareness about the importance of buying quality products.

Authorities have provided developer CWP Renewables with the tick of approval for what will be the first big battery in Australia to be added to an existing wind or solar farm with the same connection point in the National Electricity Market.

With Australia’s energy system rapidly transitioning from a traditional dependency on coal-fired power generation towards a future built on renewables, the market operator has detailed the engineering roadmap required for the country’s main power systems to operate on 100% renewable energy more frequently and for longer periods.
