Rooftop Solar Could Create Zero Demand by 2027
by Karla Lant for Futurism
The level of minimum power demand from South Australia’s grid hit a new record low — and it did so about a week after setting the previous low demand record, thanks to rooftop solar panels. On Sunday, September 17, only 587.8MW of power was drawn from the grid, beating the low mark of 786.42MW from the previous Sunday.
Additionally, where record low demand times in the past happened during the nighttime hours, these new records happened during the middle of the day despite higher overall energy consumption during those hours — as you’d expect with solar power.
According to Renew Economy, moderate early spring temperatures (therefore, fewer air conditioners running) coupled with a high rooftop solar output of more than 700MW account for the new record.
The new numbers indicate that 47.8% of South Australia’s demand for electricity is currently met by rooftop solar, up more than 10% in a single week. This is a regional best for South Australia, and probably beats any record set by any comparably-sized grid anywhere.
