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.

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.

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.

“A clear decline:” IEA says faster transition to renewables equals lower household prices
The International Energy Agency (IEA) recommends accelerating the adoption of renewable energy to lower household power prices, as it has been proven to be more cost-effective in the long run despite higher upfront costs. The IEA also dispels the myth that wind and solar energy sources are less reliable than fossil fuels, emphasizing that reduced dependence on fossil fuels can shield against market price shocks. South Australia and Western Australia serve as examples of grids remaining stable with a high percentage of renewable energy. Climate Analytics CEO Bill Hare underscores the benefits of supporting renewables, noting their rapid growth and falling prices as a win-win for both people's wallets and the climate. The IEA's report stresses the need for significant investments in grid infrastructure to facilitate the transition to renewable energy sources, as efforts to stabilize energy prices are faltering and demand for LNG and oil is declining while renewables become more competitive.

World’s biggest isolated grid hits new peak of 89 per cent renewables, led by rooftop solar
Western Australia's South West Interconnected System has reached a record high of 89% renewables, led by rooftop solar, with plans to retire coal generators by 2029 and fill the gap with new wind and solar capacity. The grid is supported by large batteries to balance supply and demand, with the federal government seeking bids for 1.6 GW of new capacity. Winners will be announced in March or April next year, and support for independent media like Renew Economy is encouraged to promote accurate information and climate solutions. Giles Parkinson, founder and editor-in-chief of Renew Economy, is highlighted as a journalist with over 40 years of experience dedicated to supporting climate solutions through independent media.
