South Australia is proving to the world that relying largely on wind and solar energy with battery back-up is incredibly cheap, with electricity prices tumbling by 30 per cent in a year and sometimes going negative

edit maybe the state is South Australia, or at least that is what the comments said but idk

    As a South Aussie, we also have HUGE amounts of roof-top solar.

    I’ve currently got a 2.8kw system and am upgrading it this year to a 16kw with a 32kwh battery. I’ll use it to charge my ev (another purchase this year, possible changing both cars) and get a bidirectional charger installed so, when there is limited power in the grid, I can sell some of it back at stupidly high prices, including some from the car too. We use about 20-40kw per day (40kw only on really hot or really cold days), so should cover us for a while.

    In case anyone wants cost breakdown, it’s going to cost about $30k, and will pay for itself due no bills in a maximum of 8 years and a lot fewer if we sell spare electricity back to the grid.
