As heat pump water heater (HPWH) installations replace gas loads with electric loads, it is important for these units to be grid-interactive so their thermal energy storage capabilities are harnessed as a load-shifting resource to help balance the grid rather than adding strain.

The TECH Market Readiness for HPWH Load Shifting Pilot aims to do just that by testing the hypothesis that though effective outreach and interventions, contractors will be critical market partners in facilitating grid connection at the time of installation.
