Energy storage is one of the hottest topics in the electricity industry today. As battery costs decline, many actors are recognizing the huge potential of storage to lower the cost of the grid and become a booming, multibillion dollar market. But although Tesla and its competitors capture all the headlines, it's always worth noting that energy storage can come from multiple sources—not just batteries—and there are many ways to bring the technology to market.
Now, a promising new initiative launched by a coalition of industry stakeholders aims to promote the concept of "community storage" in utilities across the U.S. Community storage programs let utilities aggregate customer-owned, behind-the-meter resources like water heaters, electric vehicles, and batteries to provide services to the grid. In doing so, these programs help reduce the cost of maintaining and upgrading the grid, and help lower customers' bills.http://blog.rmi.org/blog_2016_04_18_community_storage_is_a_new_way_to_think_about_reducing_grid_costs
