Cross Cutting

Partner: Itron, Dunsky

Itron surveyed ComEd customers to understand the current landscape of energy use as well as the energy savings potential for more efficient equipment and behaviors in program design.


This large-scale research project consisted of two main components:

  • Baseline study: A statistically representative survey of ComEd residential, commercial and industrial customers to determine energy-using equipment stock, efficiency, age and utilization
  • Potential study: A determination of energy-savings potential for more efficient equipment and behaviors to guide ComEd Energy Efficiency Program design

Itron took a multi-modal data collection approach leveraging web-based surveys to greatly increase sample size while reducing cost. Using ComEd’s previous potential and baseline studies as initial guideposts, the research team worked closely with ComEd to identify the highest-priority energy end uses and customer segments of interest. Approximately 5,000 multi-modal surveys were issued for the residential sector and a total of 450 onsite nonresidential surveys were conducted.

Both the baseline and potential studies break out information on public sector and income eligible customers. In addition to gaining a holistic understanding of energy end uses and energy efficiency at each survey site, the project team also investigated the prevalence of and potential for solar, electric vehicles and related charging infrastructure.

The 2020 baseline and potential studies, as well as previous potential studies, are available on the Illinois Energy Efficiency Stakeholder Advisory Group website.
