I just signed up for amberelectric.com.au. They offer the wholesale power rate (set every 30m by the electricity market authority) and the wholesale solar power feed rate, for a $15/month flat fee.
They avoid the Texas problem by limiting the maximum rate to be no more than the government regulated "default power offer" over the entire year.
Planning on getting both solar power and a battery system in the next 12 months, changing my electric hot water to a heat pump and moving to hydronic heating and split system airconditioning.
I'm also going to install a second circuit back to my smart meter that will connect to my apartment garage space so that an EV charger can be installed in the future.
