Solar PV

From an energy-hungry importer to a frontrunner in the decarbonization race, South Australia has set the bar high for how to efficiently transition to a low-emissions grid dominated by renewables. With wind and solar already supplying more than a half of its electricity, the state’s energy transition shows no sign of letting up. In fact, South Australia is gearing up to accelerate the pace of its clean energy transition and expand its big PV fleet as it moves toward its 2030 target of “net” 100% renewables.

No man is an island, but solar PV can at least allow us to live on one without having to rely on the expensive logistical nightmare of diesel fuel supply. More islands around the Asia Pacific are turning to solar PV systems combined with storage to meet their needs.

Swiss investment firm SUSI Partners is investing up to $50 million in a residential solar-plus-battery project enabling participants from communities across Western Australia to generate and consume their own clean power for up to 90% of their needs. The project, which began a year ago, and involves residents leasing solar PV and battery systems from a not-for-profit organisation.

Abundant sunshine, favorable policy settings and high power prices have long placed Australia at the cutting edge of rooftop solar uptake. The more recent utility-scale boom has further enhanced its status as a PV leader. Battery adoption, microgrids, EVs and green hydrogen are all taking shape, yet what should be an Aussie smart energy no-brainer continues to be dogged by mounting investment uncertainty and a toxic debate on the national level.

Recent Wood Mackenzie analysis suggests Asia Pacific’s decarbonisation bill could hit US3.5 trillion by 2040. US$3.5 trillion is enough to buy everyone in Sydney a house at Sydney’s inflated housing prices, or alternatively, it’s enough to buy everyone a single avocado toast at a trendy cafe.

A number of massive PV projects have been proposed for Australia’s north, with the concept built around clean power exports to Southeast Asia. Is it Desertec Down Under? Proponents are certainly hoping for more success.

Australia made its first moves to open up its energy industry in the 1990s, when the National Electricity Market (NEM) was first created, and many of the rules and regulations from back then are still in place today. But the rise of renewables in the 21st century, argues Clean Energy Investor Group Chair Rob Grant, necessitates a rethink of this market structure.

The Australian Energy Market Commission’s proposed transmission access model has come under fierce criticism from the clean energy industry for being unnecessarily complex and likely to increase the cost of capital for future generation and storage investment.

South Australia’s renewables, particularly wind, have received firm dispatchable back-up as Barker Inlet Power Station begins generating energy for the first time.

Utility-scale solar is booming in Australia. Quality assurance, especially solar panel testing, helps achieve better performance and lower costs. Best-practice testing is key, writes Michelle McCann, managing partner at PV Lab Australia, but must be planned and fully integrated into a project from an early stage. This integration ensures flow-through from panel manufacturers to commercial buyers and large project owners.
