Battery storage is very cheap already with LiFePo batteries being at about $70/kwh with 80% cycle life of 3000 cycles. That's ~2.6 cents per kwh of energy stored. With invertors, grid connections, buildings etc. (that don't wear out nearly as quickly), it will capitalise to maybe about 6 cents per kwh for multiple hour storage. Because only a small fraction of energy needs to go through storage, it will make a really small impact on overall electricity cost.
