Think of it as a kind of TiVo for electricity: A device lets you buy energy when it's cheapest and store it for later use.
In an age of flextime, when workers increasingly commute outside peak traffic flows, the delivery of electricity seems a bit, well, static. When you need it most, so does everyone else, imposing big costs and occasional brownouts on utilities and their customers. But a Washington, D.C., startup called GridPoint has a better idea. Starting this spring, GridPoint is selling a "smart box," priced from $15,000 to $20,000, that will allow business owners to manage their electricity more intelligently - and cut down on power bills.
