Utility Scale Storage

With construction having commenced on the 39 MWdc second stage of the Mannum Solar Farm in South Australia, Epic Energy has revealed it is teaming with development partner Canadian Solar to investigate further expansion opportunities at the site, including the possible installation of a battery energy storage system.

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.

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.

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.

In a decidedly confusing announcement, Swedish molten aluminium storage startup Azelio says it has secured a conditional order from relatively unknown Australian company MPG Built. Azelio says the order will see it provide “energy-as-a-service” using five of its TES.POD storage units combined with solar power.

Civil and building works have now been completed on the site of the Northern Territory’s $45 million (USD 30.2 million) big battery, known as the Darwin-Katherine Battery Energy Storage System. The 35 MVA battery is being delivered by Hitachi Energy and will deploy Virtual Synchronous Machine technology, allowing it to provide virtual inertia and system strength services to the grid.

With construction underway on a $295 million (USD 197 million) transmission project to connect the landmark Kidston Clean Energy Hub to the grid in far north Queensland, developer Genex Power has announced plans to boost the generation capacity of what is already Australia’s largest hybrid energy project combining wind, solar and pumped hydro.

Australian renewable energy startup Green Gravity plans to accelerate the commercialisation of its gravitational energy storage technology – which aims to generate clean, dispatchable energy by lowering weights down old mine shafts – after inking an agreement with global professional services company GHD.
