South Australia averages 100 pct wind and solar over week, 90 pct over last 28 days
South Australia has achieved over 100% net renewables in the past week and over 90% renewables in the last 28 days, with a mix of wind and solar power. The state aims to reach an average of 100% "net" renewables by 2027, aided by new transmission links and a growing number of big batteries. The completion of a new link from NSW and the use of battery grid forming inverters will allow the grid to run without gas generators, ensuring 100% renewables at times. The state's renewable energy capacity is set to increase with the operation of the Goyder wind farm.

Solar and wind reach 100 pct of demand in biggest isolated grid, as batteries allow it to keep its thermals on
Western Australia's isolated grid achieved 100% of demand with solar and wind energy, supported by growing battery storage. The state's high levels of rooftop solar and variable renewables are driving the green energy transition, with coal generators expected to retire by the end of the decade. South Australia is also making progress towards 100% renewables, aiming for "net" renewables by 2027. As the grid transitions, alternative solutions like synchronous condensers and grid forming inverters are being considered to ensure stability. The ultimate goal is to achieve 100% renewables without the need for traditional generators, emphasizing the importance of preparing for a coal-free grid by 2031.

Building the perfect perovskite, one layer at a time
Researchers at the University of Cambridge have developed a precise layer-by-layer vapor-phase growth method for halide perovskites, specifically CsPbBr3, on a 2D perovskite single crystal. This advancement could lead to more thermally stable perovskite solar cells, with scalable, solvent-free, and industrially compatible processes suitable for various optoelectronic applications. The research also demonstrated that uniform thickness control allows for tunable band offsets, improving charge transport and recombination dynamics. The team is now focused on integrating these structures into fully functioning devices such as solar cells and LEDs, offering promising solutions for advancing renewable energy technologies.

All-perovskite tandem solar cell with dipolar passivation achieves 30.1% efficiency
Researchers in China have developed a dipolar passivation method that reduces defects and improves charge transport in solar cells based on narrow-bandgap tin lead perovskite, enabling the fabrication of all-perovskite tandem solar cells with efficiencies of around 30% and enhanced stability. The dipolar passivation strategy strengthens the ohmic contact, promotes efficient hole injection into the hole transport layer, and repels electrons from the perovskite interface, reducing non-radiative recombination and carrier transport losses. The cell achieved a power conversion efficiency of 24.9% and retained around 87% of its initial efficiency after 1,025 hours, showing promising long-term stability. The researchers aim to further improve the dipolar passivation method for enhanced stability in tandem devices, contributing to the ongoing efforts to develop more efficient and sustainable solar energy solutions.

Australia’s most advanced renewable grid is its most secure, but NSW must scramble as it nears “no coal” scenario
South Australia is leading the way in renewable energy with a 75% share of wind and solar, making it the most secure state grid in Australia. The state has successfully transitioned away from coal-fired power stations and has implemented innovative solutions such as the Tesla big battery and synchronous condensers. South Australia is on track to reach 100% net renewables and will be able to run its grid without gas plants. However, other states like NSW and Victoria are facing challenges with the closure of aging coal-fired generators and are scrambling to secure replacement capacity for critical grid services. AEMO warns of potential risks and the need for further action to ensure system stability in the future. The closure of coal-fired power plants in Australia, such as the one in NSW, is expected to lead to a "credible no coal scenario" by 2031/32. Similar closures are planned in Victoria and Queensland in the coming years. The transition to a high renewable grid is essential for Australia to meet its 2030 and 2035 climate targets. AEMO warns that new investments and reforms are needed to maintain system security during this transition, including utilizing renewable energy sources like rooftop solar. Industry and governments are working together to manage the transition points and ensure system security.

Construction kicks off on major upgrade of transmission links to host renewables and clear path for coal exit
Construction has begun on the Clean Energy Link – North project in Perth's northern suburbs, the largest investment in Western Australia's electricity transmission infrastructure in over a decade. The project includes major upgrades to the northern section of the South West Interconnected System (SWIS) to facilitate the addition of renewable energy resources, doubling capacity in some sections and enabling the flow of wind and solar energy. This project is part of the state government's plan to exit State-owned coal by 2030 and make Western Australia a renewable energy powerhouse. The North project is set to be completed by the end of 2027, creating over 400 jobs and contributing to the state's transition towards clean energy solutions.
