Here is an interesting proposal from Steven Chu the former U.S. energy secretary about how utility companies could expand their business to provide power storage at the end customers houses:
Ten years from now, the company can install a battery in the house that stores some of that energy for the house, but also can be called upon to help balance the distribution system, which they’re dying to have.
Fact is that the utility companies are afraid of all these private solar installations and energy saving efforts because they result in decreasing business while cost are increasing. It seems they are missing an opportunity to build the distributed energy grid of the future in locations that are beyond reach otherwise: inside the houses of the consumers. The utility companies would get access to free locations which are also well protected against wind, rain, frost and heat.
