That depends on the scale I think. It's getting close to economical for private electricity use, but we're still pretty far away from the manufacturing capabilities that would allow us to store a week of power for the whole grid. And even further away if you also include energy that is currently not supplied as electricity (e.g. for heating).

This form of energy is about 1/3 the cost per MWh of nuclear (as opposed to solar/wind alone which is about 1/6th the cost). It just hasnt been that cheap for very long. Hydro as storage, better grid interconnects, demand shaping (e.g. using smart storage heaters that turn on when electricity is cheap) can bring down the cost still further.
