Caching energy at home (or should that be cashing)

There's a story at business2blog today about a venture involving Goldman Sachs, which is going to be making backup energy batteries/generators for the household use. The simple but brilliant idea is that you would draw down energy at off-peak/cheaper times and store it to draw on during peak periods.

Homes would benefit from cheaper electricity, but perhaps more importantly, the burden on the power grids would be more evenly spread thereby alleviating the need for even bigger grids and smoothing demand (or reducing the peaks). I remember in my "youth" some electricity companies in the UK operating differential pricing on this basis, the frustration being that you couldn't arbitrage this benefit in the home by "storing it"- now you can!
