Each year as summer temperatures rise, so do electricity bills, which is why we are excited to preview results from a new study of customers with EnergyHub-connected thermostats. During the summer of 2013, we helped Southern California residents save 6% on their summer electricity bills. Many utility executives would think that 2% whole-home savings was very impressive---we saved three times that amount!
A study of customers who installed an EnergyHub-connected thermostat between 2012 and 2013 showed an average 6% reduction in whole-home electricity use during summer months (June--September). The average monthly bill savings were $15.60 per customer. These reductions were purely from the "passive" behavioral effects of EnergyHub’s technology---i.e., increased adoption of daytime setbacks, behavior changes associated with users learning the cost impacts of their temperature preferences, and a reduction in long-term hold usage.
What's more, the 6% savings realized did not include "active" effects of EnergyHub's software technology, notably automatic geo-optimization through our Radius™ service using users' smartphones or EnergyHub's SmartShift™ thermodynamic optimization algorithms. We'll be examining the energy-saving impacts of those effects in an upcoming blog post.
Other notable findings from the forthcoming study and related research include:
- There was a permanent load shift of 0.26 kW between 2 to 7pm, a critical window of grid stress for utilities, which could reduce the need for demand response events
- Electricity savings were highest in August, saving an average of 17% for customers that month
- Most of the savings came from the households with above-average electricity usage
- The average customer satisfaction level with EnergyHub’s web and mobile apps was 4.53 on a five-point scale
