Remember how South Australia's power grid was a basket case less than ten years ago ?
" Batteries in South Australia have been paid to charge throughout September and October 2021, due to a record number of negative price intervals. Wholesale electricity prices were negative almost 40% of the time.The chart below from the Energy Synapse Platform shows the average intraday generation and price profile for South Australia in September.The lowest prices occur in the middle of the day, due to an abundance of solar energy (particularly rooftop solar). Solar creates a “duck curve” not only in the demand profile, but also in the price profile."
