South Australia's big battery paid for itself inside 2.5 years. That's off the scale in energy infrastructure, which never pays for itself. It also saved people of South Australia about $150 million in electricity charges. We're still stuck in a model that says generate huge power somewhere, then transmit it across the country. But solar panels are SOOO much cheaper than anything else, meaning you can put them up anywhere, and if it's a place with low sunlight you just put up lots more. It's super cheap. Then you put in batteries at all levels, from households to communities to grid-level. No need for many big transmission lines. Our own home battery gets cheaper all the time, with electricity prices going up it saves us more money every day.
