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.

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.

The Coming Slow Fade of America’s Corn Ethanol Industry
The United States corn ethanol industry is facing challenges as gasoline demand decreases due to efficiency gains, hybrid vehicles, and EV adoption. Ethanol demand is shrinking within the declining gasoline market, with higher blend rates not able to compensate for the base decline. California and New York are leading the way in transitioning to electric vehicles, while the aviation industry is projected to see a shift in fuel demand towards batteries and biofuels. Global shipping is moving towards electrification and alternative fuels, with a decline in demand for fossil fuels. The US corn ethanol sector is expected to decline by 20% to 50% in the next twenty years due to the growth of electric vehicles and the need for producers to diversify.

Big batteries overtake big solar in the world’s largest isolated grid
In Western Australia, the latest utility scale battery additions have boosted total capacity to 1,385 MW and 5,367 MWh, surpassing daily utility scale solar contribution. Battery penetration on the WEM often exceeds 20% of evening peak dispatch, targeting periods of low rooftop solar energy generation and coinciding with peak demand. Renewable energy consistently exceeds a minimum of 20% penetration on W.A.'s WEM, highlighting the need for more wind power to meet night-time demand.
