PNNL Grid-Enabled Heat Pump Study

Heat pump research is needed to better understand their efficiency in cold climates.

Did you know space heating is the largest energy user in residential homes—and the greatest opportunity for decarbonization? Heat pumps, celebrated for their energy efficiency, can also stabilize the grid through demand flexibility, making them a game-changer for energy resilience. However, in cold climates, winter demand response (DR) capabilities of heat pumps require further testing to ensure reliability and comfort.

That’s where our research at PNNL comes in. For the 2024-2025 winter season, we’re conducting a field study with 15-20 homes to evaluate how grid-enabled heat pumps perform in real-world cold climate conditions. Our goals include:

  • Assessing performance: Measuring demand reduction, occupant comfort, and system operation during harsh winters.
  • Optimizing DR strategies: Testing protocols like setpoint adjustments to align energy savings with grid needs.
  • Creating actionable guidelines: Offering insights to improve DR program success and real-world efficiency.
  • Advancing innovation: Using field data to inspire new winter-focused DR solutions.

By participating, you'll help shape the future of sustainable heating while contributing to the development of resilient energy solutions. As an incentive, we are offering two $250 gift cards for participants' ongoing involvement in this ground-breaking research.
