Grids & Integration

A trio of Victorian electricity distributors are turning to new, smarter technologies including more battery energy storage systems and demand management programs as they seek to meet changing customer needs and improve grid reliability in areas where the low-voltage distribution network is constrained.

Three groups of companies remain in the race to serve as network operator for Australia’s first coordinated renewable energy zone with the New South Wales government revealing its shortlist of candidates.

The town of Walpole on Western Australia’s southernmost tip will soon be powered by a pumped-hydro microgrid, a first for the state which is already renowned for its rollout of microgrids and distributed renewable solutions.

Australia’s most powerful energy industry participants have actively resisted the move to a low-carbon economy. Now, the country known as a sandbox for technology has become a sandbox for a new model for decarbonisation – one which has seen billionaires and giant fund managers sidestep politics to use the free market in strategic and potentially disruptive ways. pv magazine Australia’s Bella Peacock reports.

French renewable developer Neoen has signed a seven year agreement with energy giant AGL to provide 70 MW / 140 MWh of ‘virtual battery capacity’ in New South Wales.

Increased demand and continual outages at gas and coal power plants in Queensland have seen a rise in the occurrence of extreme price spikes. The timing of these spikes, typically at peak hours between 5pm and 8pm, are seeing solar revenues soar just as the sun is setting.

The CSIRO will invest $50 million in four new programs to drive critical breakthroughs in electric vehicle batteries and creating storage solution which could “mimic pumped hydro.”

In September 2021, not long after a fire at the Victorian Big Battery made international headlines, Neoen’s original “Big Battery” – the Hornsdale Power Reserve in South Australia – was sued by the Australian Energy Regulator for failing to provide all of the frequency control ancillary services it had agreed to offer. The case is now before Australia’s Federal Court, where the judgement could set an important precedent for network operations in Australia, as well as the transition to large-scale batteries.

Transgrid and the Commonwealth Government have come to a $75 million underwriting agreement for the construction of the Victoria to New South Wales Interconnector West, a key piece of network infrastructure in the Australian Market Operator’s Integrated System Plan for the increased integration of renewables and maintaining reliability amidst the retirement of coal-fired power.

Another of the five community-sized Tesla batteries the Queensland government promised to install at substations across the state is on the verge of energisation in Bundaberg.
