Abstract: Relative to flat rate pricing, time-of-use (TOU) electricity rates improve alignment of household incentives to reduce electricity consumption during times when the wholesale cost of electricity is expensive. This research seeks to understand factors of the TOU plan that impact voluntary enrollment with the purpose of identifying levers that are at the disposal of a utility to increase voluntary enrollment. We conducted an survey experiment of people living in the United States. The survey randomized the peak to off-peak price ratios, the peak hours, and the number of TOU plans being offered. Our results indicate several policy-relevant findings. On average, when only one TOU plan is offered, the peak to off-peak price ratio has no impact on enrollment decisions. Respondents who are offered more than one TOU plan are 14.2 percentage points more likely to enroll than respondents only offered one TOU plan, which suggests that the ability to compare TOU plans is an important mechanism. Further, when multiple plans are presented, the average respondent is price responsive, preferring TOU plans with a large peak to off-peak price ratio (larger price spread). Lastly, people prefer shorter on-peak period lengths when either one or multiple plans are offered.
