World’s biggest isolated grid hits new peak of 89 per cent renewables, led by rooftop solar

 Western Australia’s South West Interconnected System – the world’s
biggest isolated grid – has reached a remarkable new record high of 89
per cent renewables, led by rooftop solar.

The new peak – 88.97 per cent
to be precise – was reached at 11am on Monday, beating the previous
record of 87.29 per cent set just a day earlier, and the previous peak of
85.36 per cent set on October 23. “Another milestone for WA’s clean
energy future,” Sanderson wrote. “It’s another strong sign of the
transformation underway in our energy system as we become a renewable
energy powerhouse.”

The Australian Energy Market Operator says the record
share was led by rooftop solar, which accounted for 64 per cent of
generation at the time. Large scale wind accounted for just over 16 per
cent, with the rest from large scale solar, solar battery hybrids, biomass
and battery storage.
