Y'all may have heard me earlier assert retrofit rooftop solar + B only benefits the installing electrician (better economics where installed in new construction designed with the major roof area facing north). This equation is not static, with solar and battery costs falling year after year and no end in sight.

It would be easy for government to become addicted to taking control of residential batteries in the VPP. There is an electricity crisis in Australia once a week and the VPP is an effortless lever to pull. Then there is an argument over pricing. If the AEMO tries to diddle IFN over price paid, the matter goes straight to the Supreme Court where the beak is sure to find in IFN's favour.

It looks like the AEMO simply has Bonney Bess fully charged and on standby for the last five days. Interesting that the market can work, yet a controlling regulator finds there are too many variables to manage, even in a simple isolated grouping like SA, and just turned on the gas turbines.



There are major 'learnings' for the AEMO in this episode. The SA-VIC interconnect will be back up in a few days.
