What is the cost of time-shifting usage versus paying peak pricing versus buying some storage to charge at lower rates? At the industrial scale this becomes a game of capital expenditures versus cash flow. At the consumer scale it's a game of convenience and cost. If energy can be made cheaper at the cost of informational overhead (or less convenience), then what is the role of storage (as it itself becomes cheaper) in managing that overhead? It doesn't seem far fetched that it will play a role. Also, at some point, can I get a discounted rate on my hyperloop ticket if I sell it energy during peak demand at an under-market rate?
