This OpenMinds executive summary, from a 2025 project with Carrier and CenterPoint Energy, asks how much system-wide value battery-enabled HVAC creates and how much of it could offset the upfront cost of the battery. Carrier's first-of-a-kind system pairs a behind-the-meter battery with a high-efficiency heat pump, turning home heating and cooling from a passive load into a grid asset that stores energy when supply is abundant and discharges when the grid is stressed.
Key points
- The U.S. faces an expected energy gap of about 200 GW by 2030, and new unplanned capacity can take 5 to 20 years to build.
- HVAC accounts for about 40% of building energy use, and homes offer about 100 GW of potential controllable capacity.
- Using a large state's electricity market, the team quantified value for homeowners (bill savings), Retail Energy Providers (demand response revenue) and other partners (reduced grid congestion costs).
- Across all scenarios, total system-wide value is substantially larger than the upfront incentives required. Incentive structures are the main barrier, and a customizable value calculator gives partners a shared fact base for program design.
