Experimental Design (Public)
|
Before
We will randomize approximately 75,000 customers into four trial groups (one control and three treatment groups) in partnership with an Irish utility. Customers in the treatment groups will receive emails that promote Time of Use tariffs offered by the utility. Each treatment group will receive different communication that appeals on different motives to switch to a Time of Use tariff. The control group will not receive any communication as part of this trial.

Customers in the treatment groups will receive emails that promote Time of Use tariffs offered by the utility. Each treatment group will receive different communication that appeals on different motives to switch to a Time of Use tariff. The control group will not receive any communication as part of this trial.
