Grids & Integration

Renewable energy investors’ appetite for large-scale development in Australia appears far from sated with the New South Wales Government revealing almost 50 new solar PV, wind and energy storage projects, totalling more than 34 GW, have been proposed for the South-West Renewable Energy Zone.

Conceived by scientists in China, the device combines an integrated carbon-based perovskite solar cell module with a rechargeable aqueous zinc metal cell. The proposed system achieved an overall efficiency of 6.4%, and a steady operation for more than 200 cycles with little performance degradation.

The uptake of EVs in the years ahead will add up to staggering battery capacity, mostly sitting idle on driveways. The two-way flow of electricity from EV batteries, known as vehicle to grid, could not only enable power systems to rely on intermittent renewables, but could also be the trump card for network operators to respond to grid disturbances. However, there are still a few catches to be worked out, as Marija Maisch explains.

Queensland company eleXsys Energy has secured more than $450,000 to help finance a trial of next-generation technology designed to manage grid stability in low voltage areas, potentially allowing for an increase in the amount of distributed energy resources, including rooftop solar, that can be connected to the grid.

The New South Wales Government is forging ahead with plans to bring 12 GW of renewable energy and 2 GW of storage online by 2030 with the formal declaration of Australia’s second coordinated renewable energy zone in as many months.

Long thought of as adversaries to renewable energy, fossil fuel assets and infrastructure also present opportunities for solar, its green-hydrogen output, and smart energy storage. Natalie Filatoff reports on the opportunities and approaches the miners are taking.

The first 20MW/20MWh battery energy storage system in the 470MW/470MWh portfolio Fluence is deploying for Filipino conglomerate San Miguel Corp has started serving the island nation’s electricity network.

A proposed 900-kilometre electricity interconnector that will link power grids across three Australian states, unlocking gigawatts of new wind, solar PV and storage projects has progressed further with New South Wales network operator TransGrid confirming the Environmental Impact Statement for the project’s eastern section has been submitted.

Construction of a new $2.3 billion electricity interconnector that will link the South Australian and New South Wales energy networks is expected to commence early this year following the South Australian Government’s approval of the project’s Environmental Impact Statement.

The 162MW (AC) Columboola Solar Farm in the Western Downs of Queensland between Chinchilla and Miles has been successfully connected to the transmission network. QLD government-owned CS Energy has agreed to purchase 100% of the solar farms approximately 440GWh of annual clean energy for the next 10 years.
