Virtual Power Plants, or VPPs, are relatively mature in Australia due to the country’s high penetration of, and familiarity with, distributed energy resources. But claims of VPP success and participation may be overblown, with a considerable gaps between the numbers some platforms are claiming and the realms of possibility.

Western Australia will now offer rural and metro-area residents in its main grid the same electricity supply. The move comes after a seemingly innocuous rule change saw regional customers unable to run their air conditioning at the same time as their cooktops – a drama pv magazine Australia first reported in July 2022 which led to sustained community pressure.

Brisbane company Li-S Energy has developed its third-generation semi-solid state lithium sulfur battery cells. The 20-layer cells, produced in its facility in Victoria, are lightweight and energy dense, reaching over 400 Wh/kg.

The New South Wale government’s competitive tender for 380 MW of ‘firming’ battery capacity has now opened.

Storage specialist Fluence has launched Ultrastack, a battery energy storage system (BESS) for storage-as-transmission assets. It is designed to help network owners and operators to manage renewables curtailment, increase the use of power lines, and limit congestion.

Sandbox Solar, a solar developer and US federal grant recipient, has released a beta version of its software modelling tool for agrivoltaic power plants. It supports the design and optimisation of solar panels, as well as the crops underneath.

Western Australian battery technology company Altech Batteries has included “game-changing” sodium chloride technology in the design of its new battery 1 MWh GridPack which is expects will be up to 40% cheaper to produce than the dominant lithium-ion alternatives.

Construction of the New South Wales section of Australia’s largest energy transmission project has reached a major milestone with the first of an estimated 1,500 new transmission towers that will form a key element of the $2.3 billion (USD 1.53 billion) EnergyConnect project installed near Buronga in the state’s far west.

A consortium led by the Fraunhofer Institute for Solar Energy Systems (ISE) will test grid-forming inverters at a large-scale PV facility in southern Germany. The aim of the first tests is to examine the performance of the devices under real operating conditions, stress factors, and typical stress profiles.

Australia’s national science agency, the CSIRO, estimates the country could require a 10 to 14-fold increase in its electricity storage capacity between 2025-2050. It has released its energy storage report, forecasting demand in different sectors and summarising storage technologies.
