February 10, 2026 — Leads & Copy — An independent evaluation by Demand Side Analytics (DSA) reveals that ecobee’s Grid Resiliency service delivered 108 megawatts (MW) of essential capacity during the Summer 2025 peak demand season. The evaluation demonstrates the potential to unlock 2.8 gigawatts (GW) of capacity across the U.S. and Canada.
The study highlights the potential of ecobee’s Grid Resiliency service to relieve pressure on energy grids that are facing increasing strain from extreme weather and rising electricity demand.
Grid Resiliency (GR) is now integrated into ecobee’s thermostat optimization platform, eco+. GR enables grid operators to intelligently decrease energy demand for all eco+ enrolled homes, thereby enhancing traditional demand response programs. By streamlining enrollment and ensuring a seamless customer experience, ecobee delivers a mass-market solution that significantly boosts dispatchable capacity.
According to Tamara Dzubay, Senior Director at ecobee Energy, speed and scale are crucial when the grid is under stress. Dzubay says that the DSA report demonstrates that everyday homes can have a tangible, positive impact on improving the resilience of the energy grid.
Grid Resiliency makes minor temperature adjustments during a stress event, which can bolster reliability when operated at scale. These small, temporary adjustments are engineered to cut energy usage when needed most, all while maintaining comfort. Homeowners retain full control and can opt out of a GR event at any time. Results have shown consistently high participation rates.
Jesse Smith, partner at Demand Side Analytics, noted the similarity between the per-device load impact and participation rates of ecobee’s Grid Resiliency program and traditional utility demand response programs. He added that the Grid Resiliency service has tremendous potential to harness the demand reduction from small offsets across millions of homes.
The report examined 11 GR events across CAISO, ERCOT, and SPP territories, with over 143,000 ecobee devices enrolled. Key findings include:
Peak reductions exceeded 1 kW per device, with an average reduction of 0.65 kW.
The average homeowner participation rate across all event hours was 73%.
Total peak load reduction capability across markets reached 108 MW.
These results confirm that GR is an effective and reliable critical capacity resource, characterized by low opt-out rates and high customer satisfaction. The results also highlight that homeowners are motivated to support their communities during critical energy events, with most homes remaining engaged, even through extended events.
Lauren Shwisberg, Principal in the Electricity program at RMI, said that deploying virtual power plants is one of the fastest ways to meet near-term reliability and affordability challenges in the U.S. power system. Shwisberg added that anything that simplifies customer enrollment is a powerful way to ensure more devices already in homes are used to support the grid.
The report estimates that Grid Resiliency unlocks approximately 2,585 MW of incremental capacity in the U.S. and roughly 215 MW in Canada, totaling a potential of 2.8 GW.
ecobee’s Grid Resiliency service demonstrates that household energy reductions, when aggregated and automated, are a powerful tool for utilities to manage peak load challenges without sacrificing homeowner comfort.
