*Potential savings are based Gexa’s estimates for single -family households in Gexa’s customer base with the following approximate characteristics:  home square footage of 2,180 or more, an average monthly usage of 1,400 kWh or more, and a monthly electricity bill of $240 or more. This calculation is only an estimate and the results presented may not reflect the actual savings. Energy savings are calculated by comparing operation time for a nationwide sample of Sensi users with temperature adjustments averaging 4° in comparison to users with no adjustments. Actual savings vary based on the size and frequency of temperature adjustment, as well as occupancy, climate, housing characteristics, heating and cooling equipment, condition of equipment, home insulation, energy provider, energy usage, and other factors.

**By adjusting the temperature using flexible scheduling, remote access, and geofencing, Sensi customers saved about 23% on HVAC energy usage.

† Your thermostat temperature may be remotely adjusted temporarily by Gexa during peak periods to optimize your energy usage and help reduce strain on the electricity grid. The adjustment would be temporary, and your thermostat’s settings will be returned to normal. At any time, you may override this adjustment using your app or thermostat.
