Big batteries are solving a longstanding problem with solar power in California. Can they do the same for Australia?
When you graph electricity demand in power grids with lots of solar panels, it looks a bit like a duck, with high points in the morning and evening (when people are relying on the grid) and a big dip in the middle of the day (when many people use their own solar instead and need less from the grid). This is known as the “duck curve”. While it sounds cute, it’s become a significant challenge for energy utilities worldwide.
