This one factory churns out enough large battery storage every year to replace more than 7 power stations the size of Mt Piper. (Mt Piper powers nearly 1.5 million homes in NSW.) We need to remember too that the time these batteries will be used, mostly at night, are the times those traditional power stations have to scale right back, because people are in bed. So we’ll need much fewer of these than people might think. ‘When the sun doesn’t shine’ is when we don’t actually need much power.
