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.
