Northwest Energy Efficiency Alliance (NEEA) initiated an in-the-field demonstration of residential Heat Pump Water Heaters (HWPH), evaluating the technology’s capability to provide demand response and energy storage to the electric grid. The project was conducted in an effort to provide the US Department of Energy with data to inform and support new electric water heater efficiency standards set to take effect in April of 2015. This report outlines challenges and lessons learned from the project that may assist future HPWH control programs, but overall the project demonstrated that HPWHs can participate in demand management programs designed to either reduce peak demand or provide energy storage services to the grid, or both. For more details on the findings and recommendations, please read the full report.
