What is both possible and practical is to key the mains frequency to the

The problem of course is how much consumption is 'dispatchable' in the
sense that it can be time shifted without affecting economic activity.

I'd say that's the best option.

IMO it's better to allow the consumer to choose when to run the
appliances based on when it's viable to use the cheaper power.

Sure, most consumers won't bother, but its not feasible to have
the system turn things off and on when it decides to do that.


it's technically feasible

whether it will be popular is another matter
