Elon Musk’s big batteries could kill the duck!


A major problem with solar power has been the duck curve. Demand increases when the sun goes down, just when solar plants stop producing energy. One answer is huge batteries that store excess solar power to be used later. However, the technology needed to create such batteries hasn’t really existed at scale until now. Now maybe Telsa has invented them.

Tesla has delivered a giant battery farm with 396 stacks of batteries that can provide enough electricity to power 15,000 houses for four hours, about how long it takes to shave the peaks, to kill the duck.

These Tesla powerpacks are good for 5,000 cycles, which is low for grid-scale use. Hopefully the tech keeps improving, with more cycles and lower costs.
