I love this. It’s basically an edge cache for power, with an enormous amount of side benefits - smooths out solar power, smooths out the duck curve, and allows the grid to size closer to the average load and absorb the spikes at the edge, instead of cascading into the core.
There was an article earlier about the distribution challenges that come from large workload fluxes, too - tl;dr is the transmission lines get less efficient under higher load, so smoothing out the demand curve to the end user also raises the efficiency of the entire grid.
And as someone points out below - the proliferation of EVs also helps this, because they can act as a “deep” reservoir so the local residential batteries can be much smaller - more buffers than something expected to run the house for more than a couple hours, so that makes the whole setup even cheaper, depending on when and where the EVs are getting charged.
This comment needs to be higher than all the "but storage is not generation!!" fud in here. Didn't realize how astroturfy hn had become. "edge cache for power" is the true spirit of what this is about

It feels like politics to me, and HN is definitely not immune to partisan motivated reasoning.
