Grids & Integration

Marinus Link has locked in a 2030 completion date for the high-voltage Tasmania-Victoria power interconnection project after signing a deal worth more than $1 billion with the world’s largest cable maker.

New South Wales distribution network service provider Ausgrid has powered up a 160 kW / 412 kWh battery energy storage system in the eastern Sydney suburb of Bondi, describing it as a “fundamental shift” in the evolution of community batteries.

A team of researchers in Western Australia has outlined a new methodology to determine the minimum power rating of energy storage systems used for emergency under-frequency response. The ESS size must be calculated to maintain the frequency within the standard operating range.

The Swiss Army knife qualities of lithium-ion batteries have helped scale the technology. Now their ubiquitous nature means they are ideally placed to help electricity system operators balance the grid, argues Gerard Reid, co-founder and partner of Alexa Capital.

The 8 GW network capacity New England renewable energy zone scoping report has been released outlining the construction and operation of new high voltage electricity network infrastructure needed to connect future renewable energy and storage projects to the grid.

After the end of the Paris Olympic and Paralympic Games, the 15 solar power plants installed on the roofs of buildings in the athletes’ village will be integrated into a collective self-consumption operation once the future residents of the district have taken possession of the premises.

Libra Energy has unveiled its first major Australian renewables project, announcing plans to build an 850 MW / 3,400 MWh battery energy storage system in southeast Queensland to help soak up excess solar energy and stabilise the grid supply and demand during peak hours.

Access to rooftop solar in Western Australia has received a boost with state-owned energy provider Horizon Power expanding the reach of an internet-connected energy management project that promises to help balance energy flows on regional microgrids.

Researchers in Malaysia have proposed a new approach to identify the optimal power sizing ratio to balance PV energy capture with inverter costs. The calibrated model is said to accurately reflect the relationship between inverter efficiency and real-world system behavior.

Mining giant Fortescue Metals Group has begun commissioning its 100 MW solar farm at the North Star Junction south of Port Hedland in Western Australia, as the company progresses toward a target of real zero by 2030.
