tl;dr: From July 2026, energy retailers in NSW, South Australia, and South-East Queensland must offer households at least three free hours of daytime electricity daily (around midday), capped at 24 kWh/day, to pass on the benefit of excess rooftop solar generation. Access requires only a smart meter and opting in — no solar panels or home ownership needed — making it available to renters and apartment dwellers. Estimated savings range from $100–$1,100/year depending on how much load you can shift into the free window.
