In the end there is no realistic future where every home has an efficient battery. The bulk of power has to come from grid/utility that provides storage.

Honestly my hope was that metering like this would be an incentive to build said storage but it is not. In the end the grid/utility operators are crying missed profits and lobbying government to step in "or they will become bankrupt". It's a sad state of affairs, these utilities make money hand over fist but not doing the investments they are supposed to do.
