Could a simple redesign turn basement water tanks into real-time utility assets?

The household electric water heater, long a quiet partner in utility demand response programs, is going through a series of makeovers that just might turn it into tool that can match the challenges happening at the edge of the grid.
Some of this work involves cutting-edge pilot projects, seeking to create virtual batteries from thousands of water heaters tied together in fast-reacting, grid-responsive control systems. Canada’s PowerShift Atlantic project, or the U.S. Department of Energy-backed Pacific Northwest Demonstration Project, are good examples of this approach.
