- Pumped storage hydroelectricity grid [1] - Wall socket receiver for power-line communication [2] to schedule energy consuming devices at homes/factories - dishwashers, washing machines, heaters, freezers - this may be not to easy to match demand but at least that could be scheduled in some reasonable time range like "within 4 hours" etc. Also I would be fine to "store" cold with freezers down to -50 deg C. The receiver could display electricity bill saving to incentivise users :) - Subsidized home batteries (like Powerwall but with no need for solar part) which could be controlled by electricity supplier to balance usage - also with some power-line communication.
