Black Hills Energy

Behavioral Program Evaluation

We conducted three years of evaluation of a Home Energy Report program administered by Opower. The program was cancelled after two years; subsequent to this, we conducted a study of savings persistence based off of the full cancellation of the program (as opposed to other studies that typically base it off of the exclusion of a subset of customers). This presented a unique opportunity in that Black Hills Energy and CenterPoint Energy share similar geography and demographics in Arkansas, allowing us to study the “foregone lift” of savings due to program cancellation. This term measures the effect of continuing the program in generating longer-term savings; we essentially had “a control group for a control group” in comparing the degraded savings of the Black Hills Energy program to the continuing savings growth of the CenterPoint Energy Program. We presented these study findings at the 2015 ACEEE Market Transformation Symposium.
