United Illuminating pairs with EnergyHub, Rheem on home energy project

United Illuminating (UI), a unit of Avangrid Inc., EnergyHub, and Rheem, are pleased to announce early success in the utility’s Home Energy Solutions – Income Eligible program.

As part of a power grid management strategy, UI is using EnergyHub’s Mercury distributed energy resource management system (DERMS) to aggregate, monitor, and leverage customer deployed Rheem intelligent heat pump water heaters for demand response events.

The program has broadened UI’s demand response portfolio while creating potential for the company to use heat pump water heaters for other grid services in the future. UI is already using Mercury to manage its Bring Your Own Thermostat demand response program, Smart Savers Rewards.

Income-eligible UI customers may apply for a no-cost home energy assessment via the utility’s website. Upon completion of the energy assessment, if approved, UI will install a Wi-Fi enabled Rheem intelligent heat pump water heater in qualifying customers’ homes at no cost. 

Replacing customers’ old, less efficient electric resistance water heaters with Rheem intelligent heat pump water heaters can potentially save customers up to 50 percent on electric water heating costs, as well as help the utility meet its conservation targets. 

The intelligent heat pump water heater pilot program is one of several new distributed energy resource programs EnergyHub is launching in 2019 — signaling utilities’ commitment to leveraging a growing variety of behind-the-meter distributed energy resources for demand-side management programs.
