That $52/kWh price isn't for raw battery modules, it's for a fully packaged bulk storage system. Which means the raw battery module price is significantly less than $52/kWh. Wowsers.

I just bought an ecoflow for around $350 for 1 kWh. It uses LFP, I guess there's a lot of room for it to fall in price.

I wonder if there will be a tipping point where people start defecting from the grid, making it more expensive for people still on the grid, giving them a bigger incentive to defect.

  • Your $350/kWh for the EcoFlow is actually pretty good - that's lower to mid-range for consumer LFP power stations right now [0]. The best consumer units are still hitting around $300/kWh, but there's a long tail of more expensive options. Still a huge gap from utility-scale ($52/kWh), but the trajectory is steep.

    The "death spiral" scenario you mention is interesting - we're probably still a few years out from consumer storage being cheap enough to cause mass grid defection, but the economics are getting compelling fast. The portability premium and all the inverter/BMS/housing costs still add up compared to raw cells, but even those are dropping quickly.

Its 35 for cells.

For comparison a project in NZ recently finished cost 550 usd / kwh (which also includes site, etc)
