Exploiting the implementation of a Prepaid Electricity Program in the Department of Antioquia (Colombia), I estimate the impact that switching to this kind of programs has on users' energy consumption behavior, with particular emphasis on those that are more vulnerable from a socio-economic point of view. I find that the new scheme and the information provision is associated with a decline in electricity consumption of 15.04%, in aggregate. However, the magnitude and the direction of this effect will depend on whether the user exhibited or not overconsumption before the switch. This scheme allow users to improve their consumption paths, while their access to public electricity services is guaranteed, minimizing disconnection risks and the associated costs.
