Results

We use a well-defined, scientific approach to measurement and verification.

Opower’s methodology and results have been independently verified by leading industry analysts and non-profit organizations, including the American Council for an Energy-Efficient Economy (ACEEE), The Brattle Group, Navigant Consulting, Power Systems Engineering, KEMA, Environmental Defense Fund (EDF), as well as by established academics from several leading institutions. Our measurement protocols follow guidelines specified by Public Utility Commissions across the country, and in particular the protocols laid out in the California Public Utility Commission’s Measurement & Verification Guidelines and the EPA’s National Action Plan for Energy Efficiency (NAPEE) guidelines.

  • Time Comparison

    We use baseline data to identify test and control groups with statistically equivalent usage patterns and histories.

  • Group Comparison

    We measure program impact against a group of non-participating homes to control for external factors that may affect energy use.

  • Replication

    We measure energy use across thousands of households, over different spans of time, to increase the statistical precision of our results.
