Evaluation
Researchers partnered with the Sacramento Municipal Utility District in California to evaluate the effects of a variety of enrollment schemes in time-varying pricing plans on electricity consumption. Results show that households which were enrolled in time-varying pricing plans by default tended to stick to their default enrollment with only few households choosing to opt-out, suggesting the presence of strong default effects, meaning that people lean toward the course of action requiring the least effort by sticking with a pre-set default option
